Update gridview without refreshing the page

Question

Right now i m redirecting to same page for showing updated values in grid view. but i want to do that staying on the same page.I am using List as DataSource and not any Database.

Solution 1

    <asp:GridView ID="GridView1" runat="server" EnableViewState="false">
    </asp:GridView>

BY DOING enableviewstate=”false” we make sure we are seeing updated data.!

Solution 2

Try using an UpdatePanel

<asp:UpdatePanel ID="UpdtPnlForGrdVw" runat="server" UpdateMode="Conditional">
    <ContentTemplate>
        <asp:GridView ...></asp:GridView>
    </ContentTemplate>
</asp:UpdatePanel>

As we set UpdateMode to Conditional we mean that

We will be updating the content of the UpdtPnlForGrdVw manually.

After binding data to the gridview use

UpdtPnlForGrdVw.Update()

to update the contents of the updatepanel which in your condition will be the gridview.

You can also do this with JavaScript, check https://stackoverflow.com/a/6177348/647884, remember you won't need the opener in your case if you try the solution in the link.

Solution 3

Try following code:

 GridView1.DataBind();

Why don't you modify the DataSource of the GridView accordingly and call grid.DataBind(). Apart from that, show what you've tried.

This is not even a comment (although it is a step in the right direction).

OP hasn't mentioned that he wants to use ajax or that the flicker is the issue.

But it can be helpful to someone else who will read this "comment" )

@TimSchmelter Well Tim, you are right but it is still a solution isn't it? Plus I am just suggesting things he doesn't have to mention using ajax, right?
