Find PageIndexChanged event in client side inside ajax "OnRequestStart"

Hi,

I am using RadGrid control on my web application.
I tried to change hidden field value on server side when changing the grid page index, but the new value is not passed to the client.
I read and found out that I can recognize a page index changed inside the ajax function OnRequestStart.
How can I recognize that the trigger for the OnRequestStart function is really the grid page index change?

Thanks.

Type 'ASP.customradgrid_ascx' does not have a public property named 'MasterTableView'.

Trying to wrap the radgrid as a custom control in an ASCX control file but I'm not having much luck.
I was able to set the datasource, and get data, but I'm trying to customize the columns now, and it doesn't recognize MasterTableView

How do I do this?
Thanks,
Simone

[Solved] Grid link to execute client click only

Hello,

I have a RadGrid that have 3 command link buttons. the first 2 need to do post back to execute their function, and that is working ok.

However, the third link needs to execute only a javascript function on the client, without doing a post back. Currently, this is the way my link column looks

<telerik:GridTemplateColumn UniqueName="DDE1" ReadOnly="true" AllowFiltering="false" HeaderText="DateEntry1">
	<ItemTemplate>
		<asp:LinkButton ID="link3" runat="server" ToolTip='<%# Eval("NumberOfSeconds1")%>' Text='<%# Eval("NumberOfSeconds1")%>' OnClientClick='<%#Eval("infoPathEntry1", "redirectInfopath(\"{0}\")")%>' />						    
	</ItemTemplate>
	<ItemStyle Font-Size="Large" />
</telerik:GridTemplateColumn>

The problem is that the onclientclick is executed, but then it does the server trip, refreshes the page and removes the jquery alert I generated.

Any ideas how can I achieve this?

Can you please let me know the work around for it?

Thanking you in advance.

Open child DetailGridView in insert mode from parent row command

how can I have the child grid open in insert mode? I tried a number of different things but it keeps saying that it can't find my linq datasource control when I rebind at the detail level or the master level. I need to be able to expand a row with command button and have the child detail grid loaded in insert mode all in one click.

When the rebind is called here at any level it yields this from ajax postback.
69|error|500|Cannot find DataSourceControl with ID 'ldsVendorRatingQualifications'|

Thanks,

protected void gridRatings_ItemCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)

{

if (e.CommandName == "AddNewChildRating") {

GridDataItem parentRow = e.Item as GridDataItem;

GridTableView parentGridView = parentRow.GetClosestParentControlByType<GridTableView>();

RadGrid parentGrid = parentGridView.GetClosestParentControlByType<RadGrid>();

parentRow.Expanded = true;

//parentGridView.HierarchyDefaultExpanded = true;

//parentGridView.DetailTables[0].InsertItem();

parentGridView.DetailTables[0].IsItemInserted = true;

parentGridView.DetailTables[0].Rebind();

}
