Refresh a UserControl from another UserControl in the same parent page

Hi there,

I am struggling with the following issue:

I have an Ajax enable parent page in which I dynamically load two UserControls (UC1 and UC2) in an update panel.

UC1 contains a Gridview in which I can add new records with the help of a linkbutton in the footer.

UC2 contain an other Gridview that display the part of the data from the same underlying database table.

I would like the UC2 to rebind (refresh) when I add a new record in UC1.

Anyone could help me to wrie the code?

Cheers,

Pascal

Hello and welcome to CodeASP.NET Community @Pascal,

For your issue, please read the following MSDN article: http://msdn.microsoft.com/en-us/library/bb386452.aspx - in order to get you started for working with DataBound controls with UpdatePanels. If you understand the logic and the procedure, it will help you accomplish this in your scenario.

Hajan

Hi Hajan,

Read the article and understand about the update panel behavior however I am not sure if the Gridview in the UC2 will update as it is dynamically loaded.

Any possibility to get me started with some input?

Cheers,

Pascal

If you have both of the GridViews in one UpdatePanel, like in the following sample code:

    <asp:UpdatePanel ID="UpdatePanel1" UpdateMode="Always" runat="server">
        <ContentTemplate>
            <uc1:GridView1 ID="GridView11" OnLoad="GridView11_OnLoad" runat="server" />
            <br />
            <asp:Label ID="Label1" runat="server" Text="<%# DateTime.Now %>"></asp:Label>
            <uc2:GridView2 ID="GridView21" runat="server" EnableViewState="false" />
        </ContentTemplate>
        
    </asp:UpdatePanel>

add EnableViewState="false" to the second WebUserControl.

This will make if the UpdatePanel is refreshed to rebind with new data.

See my code and try it.

Dear Hajan,

Thanks for the guidance, in your code the UC are static, where mine are dynamic.

I tried using static UC but the UC2 will not load after the update panel refreshes.

Can you post your code? That way I will have clear view on what you are doing on your scenario

Hi Hajan,

Here after is my code, with some additional information.

I poster only the parent page because the two usercontrols code are simple ascx pages with a gridwiew.

The usercontrols (UC1 and UC2) are in two distinct Accordion panes. They are static not dynamic.

If I declare UC2 EnableViewState="Fase" on UC2 it won't load.

The updatepanel refreshes when an action is triggered in the UC1

If for instance I change UC2 to dynamic, I load it with the Sub LoadCtrl() methode, which produce the same result.

Finally the label <div><asp:Label ID="tm" runat="server" /></div> show the current time in the same pane as the UC2. The label refreshes but the gridview does not.

Dear Hajan,

Was my code helping to find how to rebind the UC2?

Thanks.

Dear Mr. Pascal,

Sorry for the delay of my response. I was quite busy.

However, here I am :).

Well, first of all, I would like to propose you to try my example on a blank new AJAX-Enabled ASPX page. This will show you how it works and the concept I've used.

Add two gridViews in a two user controls, add SqlDataSources (or other data source control) in the Web User Controls too and bind the GridViews.

Next, add the Web User Controls in the main ASPX page. Actually, this is the code that I've posted to you.

Try it and see how it works.

I couldn't try your code because there are some third-party components you use which I don't have in my own machine.

If you can't find solution yet, we will try with another workaround, or probably I will need to supply all the third-party components you use in order to test the scenario on my own machine.

Thank you,
Hajan

Dear Hajan,

Thanks for your rply, I'll try as recommanded and let you know my findings.

Best regards,

Pascal
