Find Control in asp:repeater on button click event

Question

I have a dropdown list inside a asp:repeater item template. how can I get its value on button click event.

Answer 1

Assuming that BtnSave is also inside the repeater.

You get the RepeaterItem by casting the button's NamingContainer. Then you can use FindControl to get the reference to your DropDownList:

protected void BtnSaveClick(object sender, EventArgs e) {
    var btn =  (Button)sender;
    var item = (RepeaterItem)btn.NamingContainer;
    var ddl =  (DropDownList) item.FindControl("ddlWorkflowMembers");
    // ...
}

If the button is outside of the repeater and you want to save all items, you need to loop through all:

protected void BtnSaveClick(object sender, EventArgs e) {
    foreach(RepeaterItem item in WorkflowListAfter.Items)
    {
        var ddl =  (DropDownList) item.FindControl("ddlWorkflowMembers");
        // ...
    }       
}
