Setting 'OnClick' event for asp .net 'LinkButton' in a 'Repeater'

Posted on 2009-02-11

I have a LinkButton in a asp .net repeater. I am able to set the text as desired from the databound field however I am not being able to set the onclick event.

When a user clicks the button in the repeater it needs to call a function in the codebeind and pass along a value that it is also databound.

I have tried a few different syntax and mostly I've gotten errors such 'server tag is not well formed'. The closest I've gotten is given below, however the problem is that when the repeater controls are being rendered and it is rendering the 'onclick' value it actually executes the function that should be called when the user click the button

Any help would be greatly apprecaited.
Code for the linkbuttonn:
<asp:LinkButton ID="LinkButton1" OnClick='<%# auditReport(DataBinder.Eval(Container.DataItem, "erid"))%>'  Text='<%# formatTitle(DataBinder.Eval(Container.DataItem, "title"))%>'  runat="server">LinkButton</asp:LinkButton>
and the function being called:
protected string auditReport(object sender)
        string result = "";
        Session["ERID"] = sender.ToString();
        return result;

If you are using a Repeater, you'll probably want to use the Repeater_ItemCommand function, and get the ID from there.  Could you paste the code for your repeater?  What are you binding the repeater to?

Do it like this.
Use the Command action from the link button and pass id with the CommandArgument property.

hope this help.
<asp:Repeater ID="Repeater1" runat="server">
        <asp:LinkButton ID="LinkButton1" runat="server" OnCommand="LinkButton1_Command" CommandName="MyUpdate" CommandArgument='<%# Eval("erid") %>'>LinkButton</asp:LinkButton>
protected void LinkButton1_Command(object sender, CommandEventArgs e)
    if (e.CommandName == "MyUpdate"){
        //e.CommandArgument --> contain the erid value
        //Do something

Follow jabcoco's idea.

We cant pass parameter using OnClick event handler.
You must use OnCommand.
