My gridview is shown below-
I want When I click test5 my textbox1.text = test5 and so on..
How can I do this ?

Answer 1

Please add commandname in gridview link column as below
<asp:LinkButton runat="server" id="lnklink" CommandName="displayLink" />
And add the "RowCommand" event on gridview like below
<asp:GridView ID="gvDemo" runat="server
onrowcommand="gvDemo_RowCommand" />
protected void gvDemo_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "displayLink")
{
textbox1.text=((LinkButton)e.CommandSource).Text;
}
}

You can do this both in asp as well as using client side technologies like JQUERY javascript etc, I will suggest you to use jquery since keeping such things in client side will help you improve the performance
Now when u create a grid /repeater etc ultimately .net renders it into simple html controls, and jquery or client side technologies just work over this html , here is a small example with simple html
> HTML
My data : <input type="Text" id="TxtBox"/> //in .net id u have to take care by using .clientid property
<table>
<tr>
<td width="50">
<input type="checkbox"/>
</td>
<td width="50">
SOmething
</td>
<td width="50">
<a href="#" class="someName" >LINK1</a>
</td>
</tr>
<tr>
<td width="50">
<input type="checkbox"/>
</td>
<td width="50">
SOmething2
</td>
<td width="50">
<a href="#" class="someName" >LINK2</a> //class name is important since thats what we are going deal with
</td>
</tr>
<tr>
<td width="50">
<input type="checkbox"/>
</td>
<td width="50">
SOmething3
</td>
<td width="50">
LINK3
</td>
</tr>
</table>
JQUERY
$(".someName").on("click","",function(){
$("#TxtBox").val($(this).text());
});

create RowCommand event for grid and then do the following code
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName.ToLower() == "test")
{
textbox1.Text = e.CommandArgument.ToString();
}
}
and for aspx page do the following in your linkbutton
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton ID="linkbtn" runat="server" Text="test5" CommandArgument="test5" CommandName="test" />
</ItemTemplate>
</asp:TemplateField>
or if you are binding your database table column to your linkbutton then do the following
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton ID="linkbtn" runat="server" Text='<% yourcolumname %>' CommandArgument='<% yourcolumname %>' CommandName="test" />
</ItemTemplate>
</asp:TemplateField>
