linkbutton control

[raghu3]

I have a set of 6 linkbutton controls on a page : click of each will show a part of data on the page.
How can I know which linkbutton was clicked in post back?
my sample code:

<asp:LinkButton id="a1" runat="server" Text="Name" />
<asp:LinkButton id="a2" runat="server" Text="Address" />
<asp:LinkButton id="a3" runat="server" Text="Details" />

Page_Load() {

if (this.IsPostBack()){

// Based on the link button clicked
// populate the text Box
// how to find out which button was clicked ?
}
}

Thanks

Use the click of the linkbutton click event to exectue your code.

You need to create an event for the linkbutton...

onclick="a1_OnClick" in the HTML for the linkbuttons

    protected void a1_OnClick(object sender, EventArgs e)
    {
        TextBox txt = new TextBox();
        txt = (TextBox)this.LoginControls.FindControl("NameOfTextBox");
        txt.Text = "populate";
    }

Hope this helps...

Hope everyone is having a great day!

As all the links point to similar functionality, I thought I can trap the sender in the page_load.
Makes my code more managable ...

The following is a good article:

As I have linked buttons, simple
Request.Params.Get("__EVENTTARGET")
serves my purpose.

I'd say the best option would be to create a function and add a Handles declaration for each control that needs to call it - that's a much simpler and neater way in my opinion.

You could also call code passing the option outside of you linkbutton code.

protected void a1_OnClick(object sender, EventArgs e)
{
   CallCode("a1")
}

public void CallCode(string sWhichButton )
{
   //code needed...
}

Hope everyone is having a great day!
