I'm building a site but there is a problem.
I don't know how I can access that data of grid in which row the button is clicked.
.aspx file:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="SqlEntry"
CssClass="style1">
<Columns>
<asp:BoundField DataField="ReordID" HeaderText="ReordID" InsertVisible="False" SortExpression="ReordID"
Visible="False" />
<asp:BoundField DataField="Name" HeaderText="Name" SortExpression="Name" />
<asp:BoundField DataField="EmailID" HeaderText="EmailID" SortExpression="EmailID" />
<asp:BoundField DataField="Password" HeaderText="Password" SortExpression="Password" />
<asp:TemplateField HeaderText="Delete" SortExpression="Delete">
<ItemTemplate>
<asp:Button Text="Delete" runat="server" OnClick="Grid_Click" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
<HeaderStyle BackColor="Gray" />
<AlternatingRowStyle BackColor="#CCCCCC" />
</asp:GridView>
<asp:SqlDataSource ID="SqlEntry" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand="SELECT * FROM [Entry]"></asp:SqlDataSource>
.CS file:
protected void Refresh_Click(object sender, EventArgs e)
{
GridView1.DataBind();
resetdata();
}
protected void Submit_Click(object sender, EventArgs e)
{
string str = "INSERT INTO Entry (Name, EmailID, Password) VALUES ('" + TextBox1.Text.Trim() + "','" + TextBox2.Text.Trim() + "','" + TextBox3.Text.Trim() + "');";
Connection conn = new Connection(str);
Refresh_Click(sender, e);
}
protected void resetdata()
{
TextBox1.Text = "";
TextBox2.Text = "";
TextBox3.Text = "";
}
protected void Grid_Click(Object sender, EventArgs e)
{
string str = "DELETE FROM Entry WHERE RecordID = #RecordID";
Connection conn = new Connection(str);
GridView1.DataBind();
resetdata();
}
Connection Class:
public Connection(string qry)
{
SqlConnection con = new SqlConnection(#"Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\Database.mdf;Integrated Security=True;User Instance=True");
SqlCommand cmd = new SqlCommand();
cmd.CommandType = System.Data.CommandType.Text;
cmd.CommandText = qry;
cmd.Connection = con;
con.Open();
cmd.ExecuteNonQuery();
con.Close();
}
How can I delete the data from SQL Server 2005 using this webpage?
What is the problem in the code?
You could attach a CommandArgument and a CommandName to your button that contains the ID -
<ItemTemplate>
<asp:Button Text="Delete" runat="server" CommandArgument="<%# Eval('ReordID') %>" CommandName="REMOVE" OnClick="Grid_Click" />
</ItemTemplate>
... then add a RowCommand event to the GridView -
void GridView1_RowCommand(Object sender, GridViewCommandEventArgs e)
{
if(e.CommandName=="REMOVE")
{
int orderId = Convert.ToInt32(e.CommandArgument);
//Do Sql Here
}
}

How do i transfer this data and display in textboxes in another page??
You can Use Query String or store value in the session and retrieve the value on page load of the next page.
username.Value = Request["username"];
username.Value = Session["username"].toString();
I have simple booking ticketing system for my school project and am using windows form in asp.net. i have simple search where the person can input bickup, drop off and date. am using drop down list FOR bickup and dropoff and date normal calendar attached to text box. but i can't populate the gridview e.g bus rides available from one position to another in specific dates , like from A to B in 24 of August. my date i stored as date others Nvarchar. i can bind the drop down list but the search button shows nothing.

there are a few mistakes in your code, i recommend you to read about CRUD Operations using ADO.Net and C# in ASP.Net, how to use SqlConnection and SqlCommand types. When you work with asp.net web forms you can use SqlDataSource control to provide data for your controls.

this is yours DriverDisplay :

When I click on delete button and check from debugger it is not going to GridView RowDataBound function scope. I don't know what happening here?
I have a gridview. I need to include a hyperlink to one of the columns so when the user clicks the link a popout should come with option to Edit and save. After the save the gridview should automatically get refreshed.

For the column Name I need to make a hyperlink and when clicked the popout should come to edit and view data
Not sure I fully understand what do you need but you can check out how modal popup works in MS AJAX toolkit and try to emulate sample code that comes with the download.
I check many sites and referred many codes before I could post a questions here. I am facing lot of confusions seeing them. Here is my problem.
I have a GridView and I have bound it from code behind as :
public void BindData()
{
SqlCommand comd = new SqlCommand("SELECT * FROM " + Label2.Text + "", con);
SqlDataAdapter da = new SqlDataAdapter(comd);
DataTable dt = new DataTable();
da.Fill(dt);
GridView2.DataSource = dt;
GridView2.DataBind();
}
And my asp.net for the same looks like :
<asp:GridView ID="GridView1" runat="server" ForeColor="#333333"
AutoGenerateEditButton="True" DataKeyNames="Locations"
onrowcancelingedit="GridView1_RowCancelingEdit"

And I have written my GridView1_RowCancelingEdit like:
protected void GridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
{
e.Cancel = true;
GridView1.EditIndex = -1;
}
And my GridView1_RowEditing looks like:
protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
{
GridView1.EditIndex = e.NewEditIndex;
BindData();
}
And my GridView1_RowUpdating looks like:
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
GridView1.EditIndex = e.RowIndex;
Label Locations = GridView1.Rows[e.RowIndex].FindControl("LblLocations") as Label;
//ViewState["Locations_Instance"] = Locations.Text;
Label Lamp_Profile1 = GridView1.Rows[e.RowIndex].FindControl("LblLamp_Profile1") as Label;
Label Fan_Profile1 = GridView1.Rows[e.RowIndex].FindControl("LblFan_Profile1") as Label;
Label AC_Profile1 = GridView1.Rows[e.RowIndex].FindControl("LblAC_Profile1") as Label;
string query = "UPDATE " + Label3.Text + " SET Lamp_Profile1 ='" + Lamp_Profile1 + "', Fan_Profile1 ='" + Fan_Profile1 + "', AC_Profile1 ='" + AC_Profile1 + "' WHERE Locations = '" + Locations + "'";
com = new SqlCommand(query, con);
con.Open();
com.ExecuteNonQuery();
con.Close();
GridView1.EditIndex = -1;
BindData();
//lbldisplay.Text = "Updated Successfully";
}
From this I am getting what ever row I am binding using template field as well as database columns in my GridView and Once I click on Edit in the GridView, the whole GridView disappears.
Please help me.
You can find the textbox that is generated on edit event in the RowUpdating event below and assign it to a string variable.
Then have a seperate function to update the values entered and finally call your BindGrid() function which again binds the gridview..
Note: I'm using stored procedure to update my DB table.
protected void grdKeywords_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
GridViewRow row = (GridViewRow)grdKeywords.Rows[e.RowIndex];
TextBox txtKeyword = row.FindControl("txtGridKeyword") as TextBox;
string keyword = string.Empty;
keyword = txtKeyword.Text;
UpdateKeyword(keyword.ToLower());
}
public int UpdateKeyword(string strKeyword)
{

To manually specify columns for the gridview you have to set AutoGenerateColumns="false". Now you can specify the columns that you want in your GridView. You can use both "BoundFields" & "TemplateFields" now. As shown below.
<asp:GridView ID="GridView1" AutoGenerateColumns="false" runat="server">
<Columns>
<asp:BoundField DataField="column1" HeaderText="Column1" SortExpression="" />
<asp:BoundField DataField="column2" HeaderText="Column2" SortExpression="" />
<asp:TemplateField SortExpression="points">
<HeaderTemplate>HELLO</HeaderTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("hello") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
Now you can use:
GridView.RowDataBound Event to bind data to the data row.
void GridView1_RowDataBound(Object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType == DataControlRowType.DataRow)
{
Label Label1= ((Label)e.Row.FindControl("Label1"));
Label1.Text = "YOURDATA";
}
}
if you call BindData in page load then do that:
if (!IsPostBack)
BindData();
That might solve your problem...

Make sure you have EnableViewState="true" set in your GridView. It solved disapperance-issue in my case.
try this ..
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
GridView1.EditIndex = e.RowIndex;
GridViewRow row = (GridViewRow)GridView1.Rows[e.RowIndex];
TextBox PrStyle = (TextBox)row.FindControl("PrStyle");
TextBox PrID = (TextBox)row.FindControl("PrID");
GridView1.EditIndex = -1;
SqlCommand cmd = new SqlCommand("Update dt Set PrStyle='" + PrStyle + "',PrID='" + PrID + "'");
}
