[Solved] Refreshing RadGrid after closing window

[Marco]

Hello,

I have a RadGrid with a template column (contains 3 image buttons), when I click one of the buttons a RadWindow opens with fields to edit the respective entry. After the update the window should close and the grid refresh to show the changes (using an ajax request). However, the ajax request is fired but i don't see any changes (the changes are occuring as I do check for it manually in the database). Any ideas? Here's my setup:

Masterpage:

<asp:ScriptManager ID="ScriptManagerMaster" runat="server">
                </asp:ScriptManager>
                <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
                </telerik:RadAjaxManager>

Content page:

            RadTreeNode p = null;
            p = n.ParentNode;
            while (p != null)
            {
                p.Expanded = true;
                p = p.ParentNode;
            }
        }
    }
    protected void LnkAcceptChanges_Click(object sender, EventArgs e)
    {
        int result = SqlDataSourceEdit.Update();

        ClientScript.RegisterStartupScript(Page.GetType(), "mykey", "CloseAndRebind();", true);
    }
    protected void RadSliderProgresso_ValueChanged(object sender, EventArgs e)
    {
    }
}

I apologise for all the code.

Thanks in advance.

Just to add to the post, I see the changes after a full postback (refresh in browser).

Again, thank you in advance.

I figured it out, I think. I had to specify my ajax manager (masterpage), to have itself initiate ajax requests and the updated controls be the principal content placeholder. Like so:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
                    <AjaxSettings>
                        <telerik:AjaxSetting AjaxControlID="RadAjaxManager1">
                            <UpdatedControls>
                                <telerik:AjaxUpdatedControl ControlID="ContentPlaceHolderContent" />
                            </UpdatedControls>
                        </telerik:AjaxSetting>
                    </AjaxSettings>
                </telerik:RadAjaxManager>

Thanks to all who gave this thread a look-see.

I had a similar problem, but didn't like the idea of coding anything in the masterpage for the contentpage.  Got the grid to ajax-update by adding the following to the Page_Load routine:

 

RadAjaxManager.GetCurrent(Page).AjaxRequest += new RadAjaxControl.AjaxRequestDelegate(parent_AjaxRequest);
RadAjaxManager.GetCurrent(Page).AjaxSettings.AddAjaxSetting(RadAjaxManager.GetCurrent(Page), gridResults);

The event_routine is the AjaxRequest handler and updates the controls in the edit form template of the grid.  The AddAjaxSettings causes the refresh to correctly update those controls so that the user can see the change.
