Can any one help me please???

I have just purchased RadControls and am really struggling to get the RadGrid control to work like i need.

I have one datatable in SQL where i build me hierarchy up from with simple parent/child fields. Before getting this software i originally used the standard treeview control which come with VS but my tree is getting that big the page is just way too big so i thought the grid view would be a better way of dealing with this. I also need to know how to access the cell value so i can use it in my query.

Any help would be great

Cheers

combo box inside grid

I have a combobox in the edititemtemplate of two of my grid cloumns.
The comboboxes are realted combo boxes that is the value of the first combo determines the list in the second combo.

when I select something in my first combo , the second combo takes very long to load.

Is there something I can do to improve the performance.
I am using loadondemand for the combos.

The rest of my columns have a textbox in the edititemtemplate. I tried replacing them with the gridnumericcolumn but that makes no difference to the performance of the combo boxes.

please give any suggestions.

Server side event not getting fired when the button is registered with JS>

Hi,
I have a Usercontrol which is being loaded in an aspx page.The usercontrol has a button which has been ajaxified in the aspx itself.When the user clicks the button i have to do a JS validation and depending upon whether the validation is true or false the server side click event of the button should be fired.But currently only the JS gets fired and even if the JS method returns true the server side click event of the button is not getting called.
I am using the Q1 2008 version of radAjax i.e. Telerik controls for asp.net ajax. Can anyone provide a solution for this.

Thanks,
Avik.

Client side selecting

Hi!

I have a RadGrid with client side selecting (ClientSettings.Selecting.AllowRowSelect=true).

I use a Skin (Default) to control the visual appearance of the grid.
For each item in the grid I set the CssClass (corresponding to a row definition in the skin) on server side to get the right appearance (depending on the status of the content, not the GridItemType).

I select some items on client side. It looks good and the "SelectedRow_Default" class will be applied to the selected items on client side. But as soon as I make a postback I will lose the visual appearance of the selected items. The CssClass defined on the server side will be used even if the items are still selected.

If I don't set the CssClass for items on server side then the "selected appearance" will be maintained even after postback.

My question is:
Is it possible to "apply" the "SelectedRow_Default" for all selected items on client side after postback to make sure that they look selected? Or is there an other solution to my problem?

Thanks
/Mats

Export & Paging

I'm having problems with the export settings as they don't work properly (for instance, when the IgnorePaging property is set to True, it shows me only the first page)

I have this code:

    
            private void ConfigureExport() 
        
                { 
        
                    radGridradGrid.PageSize = radGrid.MasterTableView.VirtualItemCount; 
        
                    radGrid.ExportSettings.ExportOnlyData = false; 
        
                    radGrid.ExportSettings.IgnorePaging = true; 
        
                    radGrid.ExportSettings.OpenInNewWindow = true; 
        
                    radGrid.ExportSettings.FileName = "Report"; 
        
                    //radGrid.Rebind(); 
        
                } 
        
                protected void ExportToExcel(object sender, System.EventArgs e) 
        
                { 
        
                    if (radGrid.Items.Count > 0) 
        
                    { 
        
                        ConfigureExport(); 
        
                        radGrid.MasterTableView.ExportToExcel(); 
        
                    } 
        
                }

I could use any help. Thanks.
