How to get Textbox from <ItemTemplate> in Repeater ASP Net

I have a product catalog page. When you click on the "Add Product" button, page with a cart shows up. This page has a table with an ItemTemplate inside it. Is there any way to get the value from the textBox located inside that ItemTemplate and change the value in the column Total cost in the table by clicking the button? The main problem is that I cannot access the textBox since it's in the . Thank you.

TextBox tQty = (TextBox)rRow.FindControl("txtQty");
Label tAmount = (Label)rRow.FindControl("txtAmount");
tAmount.Text = tQty.Text;
}
}
}
}

Ok, so you can set the index of the button, and pick this up in the Repeater "item command"
So, for your button, you can/want say this:
I have qty, price, and amount in the repeater. and button.
So, the markup can look like this:
Qty: <asp:TextBox ID="txtQty" runat="server" Width="130px" />
<br />
Price: <asp:TextBox ID="txtPrice" runat="server" Width="130px" />
<br />
Amount: <asp:TextBox ID="txtAmount" runat="server" Width="130px" />
<br />
<asp:Button ID="cmdUpdate" runat="server" Text="Update"
CommandName="MyUpdate"
CommandArgument = '<%# Container.ItemIndex %>'/>
So, you are now free to enter Qty, amount in any of the repeated items.
I have this:
Now, my repeater is going accross - and I think you should be using a listview since that better supports a grid + columnar layout - but it really don't mater (listview, gridview, repeater - they all work the same).
So, note how in our button we have both command Name, and command argument. In command argument I pass the row of the repeater.
So, the code looks like this:
protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
{
// update button in repeater clicked
// update amount based on qty, and price
if (e.CommandName == "MyUpdate")
{
RepeaterItem rRow = Repeater1.Items(e.CommandArgument);
TextBox tQty = rRow.FindControl("txtQty");
TextBox tPrice = rRow.FindControl("txtPrice");
TextBox tAmount = rRow.FindControl("txtAmount");
tAmount.Text = tQty.Text * tPrice.Text;
}
}
So, just pass the "index" of the repeater row as per above. We used this expression as command argument:
<asp:Button ID="cmdUpdate" runat="server" Text="Update"
CommandName="MyUpdate"
CommandArgument = '<%# Container.ItemIndex %>'/>
So, once you have the Item Index (row index), then you can run code against the one row and change that row as per above.
Edit:
So the full markup I have is this:
<asp:Repeater ID="Repeater1" runat="server">
<ItemTemplate>
<div style="border-style:solid;color:black;width:250px;float:left">
<div style="padding:5px;text-align:right">
Hotel Name: <asp:TextBox ID="txtHotelName" runat="server" Text ='<%# Eval("HotelName") %>' Width="130px" />
<br />
First Name: <asp:TextBox ID="txtFirst" runat="server" Text ='<%# Eval("FirstName") %>' Width="130px" />
<br />
Last Name: <asp:TextBox ID="txtLast" runat="server" Text ='<%# Eval("LastName") %>' Width="130px" />
<br />
Qty: <asp:TextBox ID="txtQty" runat="server" Width="130px" />
<br />
Price: <asp:TextBox ID="txtPrice" runat="server" Width="130px" />
<br />
Amount: <asp:TextBox ID="txtAmount" runat="server" Width="130px" />
<br />
<asp:Button ID="cmdUpdate" runat="server" Text="Update" CommandName="MyUpdate" CommandArgument = '<%# Container.ItemIndex %>' />
<div>
City : <asp:DropDownList ID="cboCity" runat="server" DataTextField="City"
DataValueField="City" Width="110px">
</asp:DropDownList>
<div style="float:right;text-align:center;margin-left:4px;">
<asp:Button ID="cmdAddCity" runat="server" Text="+" OnClick="cmdAddCity_Click" Height="16px" Width="12px" Font-Size="XX-Small" cssclass="btnPad" OnClientClick="AddCity();return false"/>
</div>
</div>
Active: <asp:CheckBox ID="chkActive" runat="server" Checked = '<%# Eval("Active") %>'/>
</div>
</div>
</ItemTemplate>
</asp:Repeater>
The code to load up this repeater is this:
protected void Page_Load(object sender, System.EventArgs e)
{
if (IsPostBack == false)
LoadGrid();
}
public void LoadGrid()
{
cmdSQL.Connection.Open();
strSQL = "SELECT ID, FirstName, LastName, HotelName, City, Active from tblHotels ORDER BY HotelName";
using (SqlCommand cmdSQL = new SqlCommand(strSQL, new SqlConnection(My.Settings.TEST3)))
{
cmdSQL.Connection.Open();
rstTable.Load(cmdSQL.ExecuteReader);
Repeater1.DataSource = rstTable;
Repeater1.DataBind();
}
}
so the above fills out the repeater - as noted, for a grid like layout, I would use a listview. Drag a list view into a web page.
use the wizards to connect to the database. Now blow out all the templates, only leave the itemtemplate.
Your code to load up the grid - same as above.
now, in place of the repeater as per previous screen shots?
You get this:
So your multiple lines that your building? They should be based on and around a listview. And each row can thus be grabbed, and addressed just as I did per above.
Do a google for listview examples - there is a like a billion examples.
Once you have this setup, then each row is a "thing" that repeats for you automatic based on the data from the table.
The markup for the list view - it again quite much follows the same ideas and concepts as a repeator. the listview for above looks like this:
<asp:ListView ID="ListView1" runat="server" DataKeyNames="ID">
<ItemTemplate>
<tr style="">
<td><asp:Label ID="IDLabel" runat="server" Text='<%# Eval("ID") %>' /></td>
<td><asp:Label ID="FirstNameLabel" runat="server" Text='<%# Eval("FirstName") %>' /></td>
<td><asp:Label ID="LastNameLabel" runat="server" Text='<%# Eval("LastName") %>' /></td>
<td><asp:Label ID="HotelNameLabel" runat="server" Text='<%# Eval("HotelName") %>' /></td>
<td><asp:Label ID="CityLabel" runat="server" Text='<%# Eval("City") %>' /></td>
<td><asp:CheckBox ID="ActiveCheckBox" runat="server" Checked='<%# Eval("Active") %>' Enabled="false" /></td>
</tr>
</ItemTemplate>
<LayoutTemplate>
<table runat="server">
<tr runat="server">
<td runat="server">
<table id="itemPlaceholderContainer" runat="server" border="0" style="">
<tr runat="server" style="">
<th runat="server">ID</th>
<th runat="server">FirstName</th>

<tr id="itemPlaceholder" runat="server">

</table>
</td>
</tr>

ASP.net 4.6 c# Set text when page opens

I have a page that allows the user to click the generate button to assign a random code to a text box. I want the text box to be assigned a default random code when the page opens. The text that is assigned needs to use the generate code method that the button is using. Where do I assign the text to the box when the page opens? I think it's the onload from the microsoft docs.
for example
// Override the OnLoad method to set _text to
// a default value if it is null.
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
if (_text == null)
_text = "Here is some default text.";
}
but I Don't know where to put that.

Since the generation of the page is done server-side before it is displayed to the user regarding the ASP side of things (disregarding any AJAX that is triggered and posted to the page that may be called client-side) you can just provide these instructions in the Page Load method.
If you look at the life cycle
You can see that it would be acceptable for your purpose to initialise the control and set properties such as text in the Page Load method for when the page is created. All you need is for runat="server" to be implied and to access the control from the code behind using it's ID. You can then set its innerHTML to whatever you like or it's .Text property or Value.
The assignment will look something like this:
//Front-end:
<input id="txt" runat="Server" type="text" />
//Code behind:
protected void Page_Load(object sender, EventArgs e)
{
txt.Value = "Bob123";
}
Or this if it's an ASP control:
//In the .aspx:
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
//In the .aspx.cs:
protected void Page_Load(object sender, EventArgs e)
{
TextBox1.Text = SomeMethod();
}
public string SomeMethod()
{
return "Foo";
}

The textboxes on your form are being populated with their database defaults in the Page_Load event. This is fine the first time through; however, when you click your 'degistir' button, a "postback" occurs, and Page_Load fires again and repopulates those defaults, losing whatever changes were submitted. Keep in mind that Page_Load fires before any control click events.
To fix this, you need to check for IsPostback in Page_Load to prevent your loader from firing on the update. If IsPostback is true, inhibit the load of the defaults from your database. This, in turn, should allow the update to occur with the updated data provided on your form. Something along these lines:
// code snipped...
if (Session["kullanici"] != null)
{
Response.Write("Hoşgeldiniz..." + Session["kullanici"]);
Response.Redirect("KayitAyrinti.aspx");
}
else
{
// Response.Write("Giriş Yapınız.");
}
if (!IsPostback) // <-- Add this check
{
string connectionString = "xxx;Database=xxx;Uid=xxxx;Pwd=xxx;";
using (MySqlConnection cn = new MySqlConnection(connectionString))
{
string[] keys = Request.QueryString.GetValues("id");
/// rest of code snipped
Also, be sure to modify your UPDATE statement to include a WHERE clause that limits the UPDATE to only that record with the desired ID. As it is, ALL your records will be updated!

How can I open another page when pressing the Edit button on a gridview?

I have a Gridview control in asp.net with C#.
In my application when I press the edit button from Gridview I need to open the information in another window. At this moment I use 'Response.Redirect("..")' but it opens in the same window.
I've tried:
protected void OutputGridView_RowEditing(object sender, GridViewEditEventArgs e)
{
outputGridView.EditIndex = e.NewEditIndex;
GridViewRow row = outputGridView.Rows[outputGridView.EditIndex];
string url = "http://localhost/MyPage.aspx";
Response.Write("<script>");
Response.Write("window.open('" + url + "')");
Response.Write("<" + "/script>")
e.Cancel = true;
}
But with no luck.
What's the best way to do this?

Try this
protected void OutputGridView_RowEditing(object sender, GridViewEditEventArgs e)
{
try
{
outputGridView.EditIndex = e.NewEditIndex;
GridViewRow row = outputGridView.Rows[outputGridView.EditIndex];
string url = "http://localhost/MyPage.aspx";
StringBuilder sb = new StringBuilder();
sb.AppendLine("<script type='text/javascript'>");
sb.AppendLine("window.open('" + url + "')");
sb.AppendLine("<" + "/script>");
ClientScript.RegisterStartupScript(this.GetType(), "myjs", sb.ToString(), false);
//or if the gridview is inside an updatepanel do the code given below
//ScriptManager.RegisterStartupScript(UpdatePanel1, UpdatePanel1.GetType(), "myjs", sb.ToString(), false);
}
catch (System.Threading.ThreadAbortException)
{
throw;
}
catch (Exception err)
{
//handle error here
//Elmah.ErrorSignal.FromCurrentContext().Raise(err);
}
}
As I have commented in the code above, if you are using ScriptManager, uncomment and use this
ScriptManager.RegisterStartupScript(UpdatePanel1, UpdatePanel1.GetType(), "myjs", sb.ToString(), false);
I have tested it and its working.

This code will open the window in new window. for this you need to use the ScriptManager
string BrowserSettings = "status=no,toolbar=no,menubar=no,location=no,resizable=no,"+
"titlebar=no, addressbar=no, width=600 ,height=750";
string URL = "http://localhost/MyPage.aspx";
string scriptText = "window.open('" + URL + "','_blank','" + BrowserSettings + "');";
ScriptManager.RegisterClientScriptBlock(this, typeof(Page), "ClientScript1", scriptText, true);

ASPX: Create a gridview like this
<asp:GridView runat="server" AllowPaging="True" AutoGenerateColumns="False" ID="gvSticker"
Width="100%" EmptyDataText="No sticker found for this Fisher. Click on add to Add a new sticker."
HorizontalAlign="Left" ShowFooter="True" ShowHeaderWhenEmpty="True" BackColor="White"
BorderColor="#CCCCCC" BorderStyle="Solid" BorderWidth="1px" CellPadding="3" PageSize="3"
OnRowDataBound="gvSticker_RowDataBound" OnPageIndexChanging="gvSticker_PageIndexChanging">
<Columns>
<asp:TemplateField>
<HeaderTemplate>
<table style="width: 100%">
<tr align="left">

</table>
</ItemTemplate>
</asp:TemplateField>
</Columns>
<FooterStyle BackColor="White" ForeColor="#000066" />
<HeaderStyle HorizontalAlign="Left" BackColor="#006699" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />

<SortedAscendingHeaderStyle BackColor="#007DBB" />
<SortedDescendingCellStyle BackColor="#CAC9C9" />
<SortedDescendingHeaderStyle BackColor="#00547E" />
</asp:GridView>
In data bound event add the code.
protected void gvSticker_RowDataBound(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e)
{
if (Session["FisherId"] != null)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
Label lblStatus = (Label)e.Row.FindControl("lblStickerStatus");
if (e.Row.RowIndex == 0)
{
if (lblStatus.Text.Contains("Active"))
{
btnAddSticker.Enabled = false;
HyperLink hlStickerNum = (HyperLink)e.Row.FindControl("hlStickerNumber");
if (!string.IsNullOrEmpty(hlStickerNum.Text.Trim()))
{
string urlWithParameters =
"Stickers.aspx?StickerId=" +
hlStickerNum.Text;
hlStickerNum.Attributes.Add("OnClick",
"popWinNote('" + urlWithParameters +
"')");
}
}
else
{
btnAddSticker.Enabled = true;
btnVoidSticker.Enabled = true;
}
}
}
}
else
{
btnAddSticker.Enabled = true;
btnVoidSticker.Enabled = true;
}
}
And in aspx page add a function in script tag PopWinNote to open a show modal dialog if you need a small window. This code is not actually your required code but might give you idea regarding the implementation of logic

Instead of writing directly to the response stream try this:
Page.ClientScript.RegisterStartupScript(this.GetType(), "OpenNewWindow", "window.open(...)", true);
