gridview delete command within updatepanel, and separate __doPostback() functionality - asp.net

Question

I have a gridview within an updatepanel, the rows have a delete button which removes that row.
Elsewhere, I run code to insert a row. Following this insert I run __doPostback() with the ID of the updatepanel, then in the updatepanel's load() event I call databind() on the gridview.
As soon as I implement the __doPostback() and databind, the inbuilt gridview delete stops working! :( The actual refresh/databind when adding the row works well.
How can I overcome this? I guess something may be awry in that when clicking on the delete button, the databind is conflicting with the inbuild delete/refresh functionality?
Thanks!
EDIT: Apologies if the question isn't described well...
Essentially, I wish to have a gridview with built-in delete functionality through the datasource and command column etc. inside of an updatepanel. I also want to update this panel seperately, but when I put in this separate update code (gridview.databind in the updatepanel.load) it breaks the standard delete functionality. Hope that is clear :)

Answer 1

You've tried put the UpdatePanelMode as Conditional and use UpdatePanel.Update() besides the ClientScript.RegisterStartupScript during your insertion block ?

I believe the problem is that the event is inside of the GridView and you can't access them as easily as you can with something like a Button. To register the GridView to make the Async events you need to attach it to the ScriptManager.
To do this you use the RegisterAsyncpostBackControl method.
Here is a general idea of how to do it.
<asp:ScriptManager ID="ScriptManager1" runat="server" />
<asp:UpdatePanel ID="UpdatePanel1" UpdateMode="Conditional" runat="server">
<ContentTemplate>
<asp:GridView ID="GridView1" runat="server">
<%-- your fields, etc --%>
</asp:GridView>
</ContentTemplate>
</asp:UpdatePanel>
In your code behind you do
protected void Page_Load()
{
ScriptManager1.RegisterAsyncPostBackControl(GridView1);
}
It's been a while since I've done this but I believe this will allow the GridView to function as you'd expect, except you don't need the extra DataBind() I don't believe in this case.
You can also set the UpdatePanel to Conditional and fire an UpdatePanel1.Update() on top of this as Jeison suggested.

If you still have trouble, let us know what happened.

It seems like you calling DataBind() of GridView every time the UpdatePanel load after the insert button click, it reload the data before delete reaches the DataSource.
EDIT
If so, you can add boolean eventArgument in __doPostBack(updatePanelId, "true"). And using this you could add a condition in your updatepanel load event like
if(this.updatepanel1.Page.Request.Params["__EVENTARGUMENT"] == "true"]
this.gridview.databind()
Hope this will resolve the issue.
