Can anybody help me, how to achieve this one?
Any help would be highly appreciated,
Thanks.,


To achieve the bind value in Form you need to set the TextBox value as GridView rows value within RowCommandEvent:
protected void GridView1_RowCommand(object sender,GridViewCommandEventArgs e)
{
if(e.CommandName =="EditRow")
{
GridViewRow gr = (GridViewRow)((Button)e.CommandSource).NamingContainer;
string id = gr.Cells[0].Text;
txtname.Text =gr.Cells[1].Text;
txtclass.Text=gr.Cells[2].Text;
txtsection.Text =gr.Cells[3].Text;
txtaddress.Text=gr.Cells[4].Text;
}
}
GridView :
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataKeyNames="Column1,Column2,Column3,Column4" DataSourceID="SqlDataSource1" OnSelectedIndexChanged="GridView1_SelectedIndexChanged" OnRowCommand="GridView1_RowCommand">
<Columns>
<asp:BoundField DataField="ID" HeaderText="ID" InsertVisible="False"
ReadOnly="True" SortExpression="ID" />
<asp:BoundField DataField="Name" HeaderText="Name" SortExpression="Name" />
<asp:BoundField DataField="Class" HeaderText="Class" SortExpression="Class" />
<asp:BoundField DataField="Section" HeaderText="Section"
SortExpression="Section" />
<asp:BoundField DataField="Address" HeaderText="Address"
SortExpression="Address" />
<asp:TemplateField HeaderText="Edit">
<ItemTemplate>
<asp:Button runat="server" ID="btnedit" Text="Edit" CommandName="EditRow"></asp:Button>
</ItemTemplate>
</asp:TemplateField>
<asp:ButtonField ButtonType="Button" CommandName="Delete" HeaderText="Delete"
ShowHeader="True" Text="Delete" />
</Columns>
</asp:GridView>
Or Fetch the row as :
protected void GridView1_RowCommand(object sender,GridViewCommandEventArgs e)
{
if(e.CommandName =="EditRow")
{
int index = Convert.ToInt32(e.CommandArgument);
GridViewRow gr = GridView1.Rows[index];
string id = gr.Cells[0].Text;
txtname.Text =gr.Cells[1].Text;
txtclass.Text=gr.Cells[2].Text;
txtsection.Text =gr.Cells[3].Text;
txtaddress.Text=gr.Cells[4].Text;
}
}

First, add your GridView and Display Text boxes to Update Panel
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<asp:UpdatePanel ID="updt" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="False" >
<ContentTemplate>
<center><div><h4>Student Details</h4></div></center>
<table style="width: 100%;">
<tr>
<td>
<asp:Label ID="Label1" runat="server" Text="Name"></asp:Label>
</td>
<td>
</td>
<td>
<asp:TextBox ID="Textusername" runat="server"></asp:TextBox>
</td>
</tr>
<tr>
<td>
<asp:Label ID="Label2" runat="server" Text="Class"></asp:Label>
</td>
<td>
</td>
<td>
<asp:TextBox ID="Textclass" runat="server"></asp:TextBox>
</td>
</tr>
<tr>
<td>
<asp:Label ID="Label3" runat="server" Text="Section"></asp:Label>
</td>
<td>
</td>
<td>
<asp:TextBox ID="Textsection" runat="server"></asp:TextBox>
</td>
</tr>
<tr>
<td>
<asp:Label ID="Label5" runat="server" Text="Address"></asp:Label>
</td>
<td>
</td>
<td>
<asp:TextBox ID="Textaddress" runat="server"></asp:TextBox>
</td>
</tr>
<tr>
<td>
<asp:Button ID="btnsub" runat="server" Text="Submit" OnClick="btnsub_Click" OnClientClick="return register();" />
<asp:Button ID="btnrst" runat="server" Text="Reset" OnClick="btnrst_Click" />
</td>
<td>
</td>

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

This is how to get cell value of edit row on RowCommandEvent
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "EditRow")
{
int index = Convert.ToInt32(e.CommandArgument);
GridViewRow row = GridView1.Rows[index];
string _name = row.Cells[1].Text;
string _class = row.Cells[2].Text;
string _section = row.Cells[3].Text;
string _Address = row.Cells[4].Text;
//Add this value to your text box here //
}
}

As i told before, the problem is the following. Here is an image for the look and for the asp code. I made an alternative solution, but i really want this too.

I need a code for this:
The dropdown list must contain a folder file names, and after i choose one of them, the text box on the left get filled with the path for the file like this:
~/Dokuments/10001/Teszt/Slide01.JPG
The 10001 can be changed by the top dropdown list, which contains the different test names. If you select a test, then the path changes automatically, so it is not a problem.
And then you can't change the textbox's content only one way, when you choose the default element from the dropdown list.

ImageButton in GridView TemplateField wont show AJAX Popup Modal

I have a page that displays a GridView containing an ImageButton TemplateField. My goal is to display an AJAX modal popup when one of those buttons are clicked, along with displaying the row where the button is pressed. The problem is that when I click on a button, it does not show the modal popup. I tried to use this tutorial and read several articles on this site about this issue but to no avail. How to properly fire the button event and show the popup?
Here is the snippet for the gridview:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
Width="505px" DataSourceID="SqlDataSource1">
<Columns>
<asp:BoundField DataField="ItemDesc"

<br />
<br />
<asp:Button ID="btnClose" runat="server" onclick="btnClose_Click" Text="Close"
Width="199px" />
</div>
</asp:Panel>
And here's my code for the event:
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName.Equals("atc"))
{
ModalPopupExtender1.Show();
//// Retrieve the row index stored in the
//// CommandArgument property.
int index = Convert.ToInt32(e.CommandArgument);
//// Retrieve the row that contains the button
//// from the Rows collection.
GridViewRow row = GridView1.Rows[index];
lblItemName.Text = row.Cells[0].Text;
lblPrice.Text = row.Cells[1].Text;
Response.Write("<script>alert('" + row.Cells[0].Text + "\n" + row.Cells[1].Text + "');</script>");
//// Add code here to add the item to the shopping cart.
}
}
EDIT: Added the panel code.

Try like this:
100% working and Tested
Use onrowcommand="GridView1_RowCommand" for GridView
Use display:none for Your Panel instead of Visible="false"
I Commented your alert(in rowbound) it contains js error

You didn't set OnRowCommand property of the GridView, so GridView1_RowCommand method won't be fired when you click the image button. Here's how you do it
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
Width="505px" DataSourceID="SqlDataSource1"
OnRowCommand="GridView1_RowCommand">

The gridview Gender column shows true/false instead of male/female.
Thanks!

You need a TemplateField for this. Assuming Male equates to True, this should work:
<asp:TemplateField HeaderText="Gender" SortExpression="Gender">
<ItemTemplate><%# (Boolean.Parse(Eval("Gender").ToString())) ? "Male" : "Female" %></ItemTemplate>
</asp:TemplateField>

query string and response.redirect issue

I Have a listView and I want to create a button or link that when user click,goes to a page that have a formview and it's datasourse configured :
</asp:FormView>
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:akhbarrConnectionString %>"
SelectCommand="SELECT [DarkhastId], [shakhs], [nam], [Idgharardad], [elat], [hamrah], [sabet], [karshenas], [tarikh] FROM [darkhastezam] WHERE ([DarkhastId] = #DarkhastId)">
<SelectParameters>
<asp:QueryStringParameter DefaultValue="0" Name="DarkhastId"
QueryStringField="DarkhastId" Type="Decimal" />
</SelectParameters>
so I need a link in page 1 for paasing DarkhastId with query string to page 2.
I tried these one after another but not responsible:
<asp:HyperLinkField DataNavigateUrlFields="DarkhastId" DataNavigateUrlFormatString="showprofile.aspx?DarkhastId={0}" HeaderText="پاسخ دهی" Text="پاسخ دهی" />

Response.Redirect(url);

you are doing right just get it on the page load of showprofile.aspx like this:
protected void Page_Load(object sender, EventArgs e)
{
string v = Request.QueryString["DarkhastId"];
if (v != null)
{
Response.Write("param is ");
Response.Write(v);
}
}
}
*Update: *
you need to access the DarkhastId from ListView Keys like this in the ListView1_ItemUpdated event:
protected void ListView1_ItemUpdated(object sender, ListViewUpdatedEventArgs e)
{
if ((sender as ListView) != null)
{
int id = Convert.ToInt32(ListView1.DataKeys[Index]["DarkhastId"]);
string url="showprofile.aspx?DarkhastId="+id
Response.Redirect(url);
}
}
here is reference answer:
http://forums.asp.net/t/1412741.aspx?Get+the+key+value+of+an+updated+ListView+item+in+the+ItemUpdated+event
you can see example here:

How to make this DropDownList works inside the ListView?

I have two tables in my database as following:
Employee Table: Username, Name, Job, DivisonCode
Division Table: DivisionCode, DivisionName
I am using ListView to show the information of the employee. Instead of showing the DivisionCode, I put a DropDownList that for showing the DivsionNames and of course I put this DropDownList inside the EditItemTemplate in the ListView. Everything works fine except editing the employee information. When I tried to change the division of the employee, I got the following error:
Cannot insert the value NULL into column 'DivisionCode', table
'psspdbTest.dbo.employee'; column does not allow nulls. UPDATE fails.
The statement has been terminated.

So how to solve this problem?

Add this to your DropDownList SelectedValue='<%# Bind("DivisionCode") %>'
and remove AutoPostBack="true"
