How to set EnableRangeFiltering in code-behind?

I cannot figure out how to set the EnableRangeFiltering and EnableTimeIndependentFiltering properties in my code-behind when I create my columns. GridBoundColumn does not have these properties, and I cannot cast a GridBoundColumn to a GridDateTimeColumn, which does.

TreeView checkboxes not maintaining viewstate?

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?

<telerik:RadTreeView ID="treeView" runat="server" DataFieldID="ID" DataFieldParentID="ParentID" DataTextField="Text" DataValueField="ID" Skin="Outlook" CssClass="tree" CheckBoxes="true" OnClientNodeChecked="ClientNodeChecked" EnableViewState="true">

<DataBindings><telerik:RadTreeNodeBinding CheckedField="Checked" Checkable="true" /></DataBindings>

<NodeTemplate>......

Use different Template for Active Tab

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.

Uncheck "All" when child is un-checked OR Check "All" when you check all children?

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?

[Solved] FindControl not working on Delete

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?

Private Sub RadGrid1_ItemCommand(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGrid1.ItemCommand

Select Case e.CommandName

Case RadGrid.PerformInsertCommandName

Dim editableItem As GridEditableItem = CType(e.Item, GridEditableItem)

Dim val = DirectCast(editableItem.FindControl("tbVal"), TextBox).Text

PerformInsert(val)

Case RadGrid.UpdateCommandName

Dim editableItem As GridEditableItem = CType(e.Item, GridEditableItem)

Dim val = DirectCast(editableItem.FindControl("tbVal"), TextBox).Text

PerformUpdate(val)

Case RadGrid.DeleteCommandName

Dim editableItem As GridEditableItem = CType(e.Item, GridEditableItem)

Dim val = DirectCast(editableItem.FindControl("tbVal"), TextBox).Text

PerformDelete(val)

End Select

End Sub

Changing the DataBinding Behavior

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?

[Solved] Hiding NestedViewTemplate of DetailTable

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.

RadAsyncUpload does not handle or catch FileSharing error

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.

OnClientValidationFailed function for checking if failure due to file being uploaded is open

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.
