I have a page with two tabs on it.  When clicking a tab there is an ajax postback.  On the first tab is a tree control with check boxes enabled.  The tree is loaded on page load if it is not a postback.  If I check some boxes in the tree, go to the second tab, then back to the first tab, all the items in the tree are unchecked.  What am I missing?

Does anyone know if there is a way to use a different template for the Active tab as opposed to the inactive tabs?

I have a button I want only on the active tab and I don't want it to show on the other tabs. Is there a way to do this? I'm not finding anything in the demo pages or the documentation.

Any help with this would be greatly appreciated.
Thanks.

Hi,

When I check the root "All" nodes, all the children get checked as expected.

1. However, when I un-check one of the children,  I would expect  the root "All" node to be unchecked but it stays checked.
2. Also, on a cleared treeview, when I go through and check all the chidren, I would like the "All" to be automatically checked.

Are there options to do this or does all of this take custom script?

I am doing something like the below. When I try to do a delete, however, I'm getting a NullReferenceException. Apparently, the FindControl doesn't find the control on delete, so when it tries to access the .Text, it causes the exception. Shouldn't it find the control?

I'm using the ItemsRequested event to databind my RadComboBox by searching the database for the Text typed in the textbox portion on the ComboBox. The only problem is, when the user initially clicks into the textbox the ItemsRequested event immediately fires so it pulls in all possible data. Is there a way to not fire this event when the user clicks into the textbox -but- still fire the event if the user clicks the down arrow on the ComboBox itself?

I've the following nested Grid structure.

<telerik:RadGrid ....>
   <MasterTableView...>
         <DetailTables>
            <GridTableView  Name="Users".....>
                  <Columns>
                          <telerik:GridBoundColumn UniqueName="Status" DataField="Status" HeaderText="Status"  AllowFiltering="false" />
                  </Columns>
                 <NestedViewTemplate>
                              ...................
                 </NestedViewTemplate>     
              </GridTableView>
           </DetailTables>
      <Columns>
           ............
      </Columns>
   </MasterTableView>
 </telerik:RadGrid>

I want to hide the NestedViewTemplate if "Status" has some specific value.

I'm binding the DetailTable as follows and probably can access the current item's Status value in the same event but not sure how to do that.

 protected void RadGridTest_DetailTableDataBind(object source, GridDetailTableDataBindEventArgs e)
        {
            GridDataItem dataItem = (GridDataItem)e.DetailTableView.ParentItem;
            switch (e.DetailTableView.Name)
            {
                case "Users":
                    {
                        int testID = Convert.ToInt32(dataItem.GetDataKeyValue("ID"));
                        e.DetailTableView.DataSource = UserInTest.GetUsersInTest(testID,"Untaken");
                        break;
                    }


            }
        }

So, how can I access the current item's Column values of DetailTable and the NestedViewTemplate to hide it if the column (Status) has a certain value.

There doesnt seem to be a way to get around the FileSharing error when a user attempts to upload a file that happens to be open on their own desktop locally (like an Excel file).

Why hasn't Telerik fixed it yet? If so what is the workaround 'cause it ain't built into the control and all the relevant topics deadend with no resolution.

Hi, I am using the RadAsyncUpload without enabling plugins, so I am using straight-up javascript on my page. In other words I have the property DisablePlugins="True".

My problem is that I can not distinguish the reason for error when the user atempts to upload a file that happens to be open at the time of the upload attempt, essentially this is a file-sharing error.

I know that you can distinguish the difference from the wrong extension and the max size errors by this post:

http://www.telerik.com/help/aspnet-ajax/asyncupload-onclientvalidationfailed.html

I cannot, however, find javascript code that will distinguish these two possible errors:

1) wrong extension
2) max file size

...as well as

3) file-sharing (while the file is open and upload attempted on it)

All three at once.

???

There seem to be solutions if you are using Silverlight, but if you are not, you do not have access to same objects and properties that you would if I was assuming the use of Silverlight.

Hello!This is a rather large post and if a support ticket is needed that one can be created. The problem is that we are using a RadGrid with check box filtering and when the first item check box is selected then deselected the filter dropdown closes but the first item check box is still selected. By first item I do not mean the “Check All” check box but the very next check box after that one. What does work is after selecting the first check then selecting and deselecting any other check box will clear the filter. Also, the problem does not happen with any other item check box except the first one located in the selection dropdown below “Check All”. This means that, on start, if you select the second item checkbox, or any other but the first, then deselect it the filter clears. Below is a copy of the code below:Thanks,Steve Holdorf
