Thanks

Hello all,

I have a RadGrid that I'm using wich has the Web2.0 skin applied to it. Is it possible to disable the ability to select a row by clicking anywhere on the row, only allowing to select by checking the checkbox?

Thanks a lot for your help!

Is it a known limitation that the CSV export doesn't export the contents of the detail tables?  I've got a single method to handle the export and when i export to either Word, Excel or PDF the detail table is included.  But when i choose CSV only the parent table is included in the results.  The code is very simple and was pulled mostly from some other posts i saw on here about other peoples export problems.

        void lbtnExport_Click(object sender, EventArgs e)
        {
            rgComparativeReport.ExportSettings.FileName = "Comparative Report Export";
            rgComparativeReport.ExportSettings.ExportOnlyData = true;
            rgComparativeReport.ExportSettings.IgnorePaging = true;
            rgComparativeReport.ExportSettings.OpenInNewWindow = false;
            rgComparativeReport.MasterTableView.HierarchyDefaultExpanded = true;
            
            for (int i = 0; i < rgComparativeReport.MasterTableView.DetailTables.Count; i++)
            {
                rgComparativeReport.MasterTableView.DetailTables[i].HierarchyDefaultExpanded = true;
            }
            
            rgComparativeReport.Rebind();
        
            if (ddlExport.SelectedValue == "Excel")
            {
                rgComparativeReport.MasterTableView.ExportToExcel(); //this works fine
            }
            else if (ddlExport.SelectedValue == "Text")
            {
                rgComparativeReport.MasterTableView.ExportToCSV();  //This only exports the parent table
            }
            else if (ddlExport.SelectedValue == "Word")
            {
                rgComparativeReport.MasterTableView.ExportToWord(); //this works fine
            }
            else if (ddlExport.SelectedValue == "PDF")
            {
                rgComparativeReport.MasterTableView.ExportToPdf();//this works fine
            }
}

Thanks!

Hi, I've seen that theres some word counter and character counter on buttom left corner of radeditor on some of the samples. But seems like its not updating when Im adding some text. How can I make use of this to change when ever I enter in some text? And how can I limit the user to stop entering whenever it reaches word count limit. like for instance 50 words max..

Thanks  advance,

Hi,

We have a gird with a export function. It works very well. However, when there are 5000 items in the grid. Once fire the export function, it will give a exception:"

System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host

"

I was wondering if export function has a maximum limit or if you have any solution for this.

I appreciate your help

Thanks,

I'm following the example  for cascading combo-boxes as found at: http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/multiplecomboboxes/defaultcs.aspx

In my exmample I just have Country / City(region)

The problem I am having is this... I have the code working where the Country uses the OnClientSelectedIndexChanged which calls my javascript function "BindRegions"...  BindRegions in turn uses the Client-Side API and calls the regionsCombo.requestItems() method to cause an AJAX call to occur back to the server-side code for the apporpriate combo box.  The Regions combo box is databound (refreshed) in that event and then the expected client-side javascript call to ItemsLoaded occurs which selects the 1st item in the list.

When I click a 'Update' button on my form (CommandName="Update" defined on the button - no click event code present) a series of events occur and eventually I invoke a method which populates an entity from the controls on that screen (which actually is a user control template for a grid editor template).   When I check the controls, their values are not set to the expected values - which I suspect is due to not having AutoPostBack enabled - which leaves me in a pinch.

How do I do the "client-side/AJAX" approach but still have the correct values up in the server-side code?   On a prior project where we had cascading combo-boxes (i.e. Country/State or Year/Make/Model) it was done with AutoPostBack enabled and no client-side javascript at all...

So I have 2 questions....

(A) which is the "right" approach - using RadAjaxManager and Post-Backs or the example given from the ComboBox section of the web-site - this was frustrating in that the 'reccomended' approach is what I would expect to find here... 

(B) How do I make the approach shown at the link stated above work while still having access to the right 'selected' values (SelectedItem, SelectedValue, SelectedIndex, etc)...

Hi,

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Script control 'gridEnderecos' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors().

Here is my code:


What is happening??
