Hi,

I am adding link button dynamically to a gridview.

LinkButton av = new LinkButton();

On Page_init()

C#

protected void Page_Init(object sender, EventArgs e)
        {
            av.ID = "lnkAssetView";
            av.Text = "LinkButton";
            av.Width = 15;
            av.Click += new EventHandler(lnk_Click);
        }

EventHandler for LinButton

C#

protected void lnk_Click(object sender, EventArgs e)
{
 // My code
}

Gridview OnRowDataBound

C#

protected void OnRowDataBound(object sender, GridViewRowEventArgs e)
{
      if (e.Row.RowType == DataControlRowType.DataRow)
      {
            e.Row.Cells[col].Controls.Add(av);
      }
}

When I click on LinkButton, postback is not happening, and linkbutton got disappears.
Please help me how to fix this.
Thanks in advance

There is no need to generate Click Event for Linkbutton just Set CommandName property of your LinkButton as 'MyCommand' and use RowCommand Event of GridView.
write following code in RowCommand Event to check whether the link button is clicked or not.

   if(e.CommandName == "MyCommand")
{
      //do the operation here
}

Hai
Why u add link button dynamicall in grid view,why u not try to add link button for one field like if u have 3 colums in grid view like ID,Name and Address. in Name column u can add link button. Textbox used show value and link button used for edit users for further process, try my code

ASP.NET

  <asp:TemplateField HeaderText="Name">
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("Name") %>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:LinkButton ID="LinkButton4" runat="server" CommandArgument='<%#Bind("UserId")%>'  CommandName="EditUser" Text='<%# Bind("Name") %>'>LinkButton</asp:LinkButton>
</ItemTemplate>
<HeaderStyle HorizontalAlign="Left" />
<ItemStyle HorizontalAlign="Left" />
</asp:TemplateField>

VB

Protected Sub gvAll_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles gvAll.RowCommand
        If e.CommandName = "EditUser" Then
'Ur operation codings
End If
    End Sub

in above grid view code i will add link button for name field,so it show Name with link button,if u click name it act as link button.

Note : u not mention for use of link button,for delete,edit ? in my eg used for edit users in grid view,if u want delete u need to use separate link button.so pls mention for what purpose u use ?

Regards
Aravind
