Hi,

Would you provide a sample for RadGrid Q1 2010 Export and Grouping together?
I tried to build a page with your drag-&-drop column header grouping, then export the grouped grid data to excel.

Thanks

Hello Daniel,

I'm not sure whether you prefer the HTML Excel or ExcelML format so I picked up the latter.

I hope this helps.

one problem,

I used your sample pages, and remove SQlDatSource, bind the RADGrid to a datatable in codebehind, grouping is fine, but if I click subgroup arrow try to minimize the subgroup, following error:

Invalid postback or callback argument.  Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page.  For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them.  If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

google this error, I added EnableEventValidation="false" to page like following:

<%

@ Page Language="C#" EnableEventValidation="false" AutoEventWireup="true"

no error any more, but subgroup min arrow not working.

Is it because codebehind databind() not working properly?

We could not use SQlDatSource in our project since we have custom datalogic to create our datatable..

thanks

Hello Daniel,

Judging by the error message, I suppose you bind RadGrid on every page load. I recommend you use advanced data-binding to avoid such issues:
Advanced Data-binding help topic
Advanced Data Binding online demo

Let me know if you need further assistance.

Thanks, it works partially, still one problem:

we could not load RadGrid in Page_Load event, we need load it only after user click button:

protected void Button1_Click(object sender, System.EventArgs e)
{
//loadRadGrid here.
}

but if I put OnNeedDataSource in html,

 

<telerik:RadGrid ID="RadGrid1" runat="server"

 

 

OnNeedDataSource="RadGrid1_NeedDataSource"

it will automatically load the RadGrid when Page_Load.

How to load radGrid only after button clicked?

thanks

Problem to use 

 

OnNeedDataSource="RadGrid1_NeedDataSource"  and 

 

RadGrid1.MasterTableView.ExportToExcel();

 


following error:

Script controls may not be registered after PreRender.

I tested to commen out  // RadGrid1.ExportSettings.Excel.Format = Telerik.Web.UI.GridExcelExportFormat.ExcelML; like following:

 

protected void ExcelExport(object sender, System.EventArgs e)

 

{

ConfigureExport();

 

// RadGrid1.ExportSettings.Excel.Format = Telerik.Web.UI.GridExcelExportFormat.ExcelML;

 

RadGrid1.MasterTableView.ExportToExcel();

}


I could export to Excel Html format without error. 

How to export ExcelML format?

Please advise how to fix.

thanks

Hello Daniel,

Question 1: we could not load RadGrid in Page_Load event, we need load it only after user click button:
You don't need to bind RadGrid on initial load - you can use an if statement in the NeedDataSource handler and bind RadGrid only if the desired condition is satisfied.

Question 2: Problem to use ExcelML
Do you use RadFilter and if yes, which version of RadControls you have? If this is not the case, please post your markup here (or attach the code to a support ticket) so I can examine your approach.

2.
How to export the collapsed grouped grid?

When I export excel html, only data in expanded group could been exported, how to export all the data for single page export and for all the pages export?
I tried some code(see my commented code in export function), but if I could export the data in collapsed group in single page, then all the pages export could only export data in expanded group.

Thanks for the help.

Hello Daniel,

I created a runnable sample project based on the provided code. May I ask you to modify it so that I can reproduce the aforementioned problems on my end?

Please note that the groups will always be in expanded state when exporting to ExcelML.

Hi all,

I'm in the same trouble as described above.
I'm getting the same message error "Scripts may not be registered after PreRender" with my export settings in ExcelML mode.
There's a solution I can implement here to workaround this problem?

Hello Balaji,

I would recommend that you disable AJAX using the client-side API as explained here:
Export from Ajaxified Grid

Let me know whether this helps.
