Hi Team.
We have a scenario where we want to conditionaly hide the detail tables. Below is our structure and we need to hide the childHeader and childRow. 
.aspx
<telerik:RadGrid>
 <MasterTableView >
    <DetailTables>
      <telerik:GridTableView name="Parent">
      </telerik:GridTableView >
    </DetailTables>
<DetailTables>
      <telerik:GridTableView  name="ChildHeader">
         <DetailTables>
            <telerik:GridTableView  name="ChildRow">
           </telerik:GridTableView >
        </DetailTables>
    <telerik:GridTableView >
</DetailTables>
</MasterTableView>
</telerik:RadGrid>


.cs

 protected void radgrid_DetailTableDataBind(object source, Telerik.Web.UI.GridDetailTableDataBindEventArgs e)
    {
        GridDataItem dataItem = (GridDataItem)e.DetailTableView.ParentItem;
        switch (e.DetailTableView.Name)
        {
            case "ParentRow":
                {
                    //code for parentrow detail table here
                }
            case "ChildHeader":
                {
                   //code for ChildHeader detail table here
                    break;
                }
            case "ChildRow":
                {
                    //code for ChildRow detail table here
                    break;
                }
        }
Now, DetailTableDataBind method iterates on each detailTable, Is it possible to remove the detailtable so that it does not even render and code in DetailTableDataBind method for childHeader and childRow does not execute. Right now its erroring when it goes in these case statements.
So the requirement is to hide these detail tables conditionally and not execute the code for child header and chidRow in above case statement

Hey all,

I have a time picker control that allows me to pick a time from a set of business hours. Normally, those hours run from around 9AM until (at the latest) 10PM. Since the times appear within the same day, there is no problem. Occasionally, however, our business hours go until around 3AM. 

I can set the min/max times well enough. The control renders the time blocks (every 30 minutes) appropriately, but I cannot select or enter any time past midnight (Even though the times are rendered in the control). I can validate that the selected time falls between the established min/max date-time during the OnSelecting event but it still throws an error and prevents the time from being selected.

How do i get around this? This is a pretty significant business need for us, and i would hate to have to render the control based upon what the current time is, especially since our business folks may have to go back and enter data retroactively.

Help?

I have a RadGrid in batch model (EditMode = "Batch") in <CommandItemTemplate> have a button (SAVE) that calls a javascript function that will call the get_batchEditingManager () method saveChanges (mastertableview);., and server side I I'm Telerik.Web.UI.GridBatchEditingEventArgs function well, the code is working correctly, however, if the server side function of an error, the postback happens and I lose the information that was added on the client. 
How do I not lose this information on the client side if my GridBatchEditingEventArgs server side of an error?

Hi

I've a RadTreeview inside a Radcombobox, and it can be quite long. Is it possible to retain the scroll position when a new value is required. Currently the user is taken to the top of the tree, the current selected node is highlighted, but I'd like to start scrolling from the current selected node.

Hello Telerik Teams

     I create RadGrid and set AutoGenerateColumns="True", and use EditMode="PopUp". When edit form pop up. I don't know how to get value from auto generated edit form to insert or update to Database. I google it but I don't find any solution yet. Please help me.

Thank you very much.

Is there a way to simulate progress?

I'm attempting to use the custom progress with an Input File object.  It is the processing of the file that I need to simulate but there aren't any measurable steps as such. 

I note that I've tried to use the input=file demo example that does not have any codebehind code, and the only way I could get the ProgressArea to display was to put code in the codebehind of the button click.

There is only 1 file to be uploaded, therefore the "While" is really only needed once otherwise it loops through the processing repeatedly.

The actual processing of the file is done using an external method from the project.

Perhaps I'm missing something?

Thanks
