i have radcombo with emptymessage even though not selecting any value it is postbacking....

my code is

 

 

<telerik:RadComboBox ID="Commodity" AppendDataBoundItems="true" EmptyMessage="--Select--"

 

 

 

Width="80px" runat="server" CheckBoxes="true" DropDownWidth="150px" AutoPostBack="true" EnableCheckAllItemsCheckBox="true"

 

 

 

CheckedItemsTexts="DisplayAllInInput" OnSelectedIndexChanged="gvNetExposurefilter_SelectedIndexChanged">

 

 

 

</telerik:RadComboBox>

 

I'm using the EnableAutomaticLoadOnDemand with a RadComboBox, the EntityDataSource is defined in code behind and connected with the RadComboBox.

When I open the DropDown of the RadComboBox I get this error:

Object reference not set to an instance of object

There is an example of how to define a datasource in the code behind in this case? Is possible using EnableAutomaticLoadOnDemand?

Is it possible to change the start time 12:00AM to "Open"  and end time 12:00AM to close on the picker?

Hi,
We are using having parent child hierarchical Telerik Grid. The grid is containing large number of records(77506 items in 7751 pages).After 2-3 mins,after clicking the Export to Excel button, It's throwing Exception as "Exception of type 'System.OutOfMemoryException' was thrown."



Using the below code for Export to Excel button click event.

gviewAuditTrial.MasterTableView.HierarchyLoadMode = GridChildLoadMode.ServerBind;
            gviewAuditTrial.ExportSettings.Excel.Format = GridExcelExportFormat.ExcelML;
            gviewAuditTrial.ExportSettings.IgnorePaging = true;
            gviewAuditTrial.ExportSettings.OpenInNewWindow = true;
            gviewAuditTrial.ExportSettings.FileName = "CRF_Details";
            gviewAuditTrial.ExportSettings.ExportOnlyData = true;
            gviewAuditTrial.MasterTableView.ExportToExcel();

Please let me know the solution for this.

Thanks,

I have a grid that is pulling data from a stored procedure. When I export, I want to query another stored procedure that has many additional columns of data returned. Is it possible to bind my grid to a separate datasource prior to exporting to excel or pdf? It is not an option for me to loop through the columns returned and show/hide each one. Any thoughts are appreciated!

Hi Everybody
I m stuck.. my radgrid fetches data from a stored procedure ..(DeptID,SubDeptID,DocSubject,DateUploaded).Can I have a select button (like in asp.net grids) which can be used to fire selectedindexchanged event. On the event of slectedindexchanged I want to fetch the rows values for particular columns..

I am getting the error "Only one instance of a ScriptManager can be added to the page".

How to fix this?

Hi , 
  I am trying to understand how to use a GridButtonColumn as an Edit button to display my FormTemplate. A few questions.  When I use it, the form magicaly appears. Thats great, but the control freak in me is puzzled.  I would like to control when it displays the form ?
  
  1) When I use a GridButtonColumn, I see it comming into the ItemCommand event, but it disappears, then the form appears. Is it the CommandName, CommandArgument or UniqueName that goes somewhere beyond that to display the actual form ? What events, properties or code is used to turn on a FormTemplate ?  Perhaps the code that turns on the form is expecting a certain combination of CommandName, CommandArgument or even UniqueName ?  Or maybe on of the 'on' properties (onInsert, onUpdate, etc) in combination with ?
  2) Is it just good Telerik to always use the GridEditCommandColum for this ?
  3) Why is there no GridDeleteCommandColumn or is the GridEditCommandColumn used for delete - I see there are delete like properties there ? And I have seen code to that effect - Is this the standard ?
  4)  Is there any documentation explaining the how, why and when for the use of the GridEditCommandColumn vs GridButtonColumn ? Or is the GridButtonColumn intended for all other button uses except Edit and Delete ?
  5) There is some code that requires a UniqueID, but the GridEditCommandColum and GridButtonColumn only have the UniqueName.   

   Sorry, looks like I have 10 "?" for 5 question Items :-)

   When I test changing CommandName, CommandArgument or even UniqueName in certain combinations, I am beginning to think there is a conflict of sorts when I use a  GridButtonColumn for Edit vs a GridEditCommandColumn to display the form.
 
 thanks,
 David
