Expanding RadTreeview node throws an error saying "error on callback"

In a webapge, We have a RadTreeview in the left pane, on click of any of the Radtreeview node, we are displaying the corresponding node content in the Radgrid.We have implemented few functionalities on the left and right click of the tree node. Our application would be used by lot of users at a given point of time.

On few instances the tree view would stop working. On expanding tree node say Folder 8.0, throws an error saying "error on callback" and also on click of node (Folder 8.0) it will not show the corresponding content in the Radgrid.

Finally the folder 8.0 becomes unusable and to make it to work, we need to reset an IIS.
This is happening on our production environment and doing an IISRESET on the server is not feasible at all times.

What is this error? could you please give us a solution for this kind of problem.?

Regards,
Deepak

Format column (currency vs percentage)

Currently have this code working however I would like to take it a step further especially in the grouping footer as it will sum the total. We have columns that are returned as "Decimal" however they could either be currency or a percentage. Is there anyway of way to check the number that is being returned to I can either perform a Sum or Avg?

All of my percentages are returned from the database as .### (ie .435).

Also can I create a "dynamic" total line when they group. Just a simple "Totals for {0}", ({0} is what they selected to group on and anyway of making just the group footer bold?

Protected Sub _SearchResults_ColumnCreated(sender As Object, e As Telerik.Web.UI.GridColumnCreatedEventArgs) Handles _SearchResults.ColumnCreated

If e.Column.DataType.Name = "Decimal" Then

CType(e.Column, Telerik.Web.UI.GridBoundColumn).DataFormatString = "{0:N2}"

CType(e.Column, Telerik.Web.UI.GridBoundColumn).Groupable = True

CType(e.Column, Telerik.Web.UI.GridBoundColumn).Aggregate = Telerik.Web.UI.GridAggregateFunction.Sum

e.Column.ItemStyle.HorizontalAlign = HorizontalAlign.Right

End If

'Specify the location of the Images

e.Column.FilterImageUrl = "../images/Grid/Filter.gif"

e.Column.SortAscImageUrl = "../images/Grid/SortAsc.gif"

e.Column.SortDescImageUrl = "../images/Grid/SortDesc.gif"

End Sub

Add Alt or Title to image on GridHyperLinkColumn

I am using a GridHyperLinkColumn with an ImageUrl defined. This produces a column with an image as the hyperlink. I want to add an ALT or Title tag to the image so that the end-user will know what clicking the image will do. There does not appear to be an "alt" or "title" property for the GridHyperLinkColumn. I've tried using the "text" property, but it does not work. Also, using the "HeaderText" property is not an option as I have the headers blank for those columns. Below is a sample of my code:

<telerik:GridHyperLinkColumn
ItemStyle-Width="20px" 
UniqueName="EditStudent"
ImageUrl="~/Common_Images/icons/View_Student.gif"
HeaderText=""
DataNavigateUrlFields="UserId"
DataNavigateUrlFormatString="~/Secure/EditStudent.aspx?uid={0}"
AllowFiltering="False" />

The screen shot shows four columns, each a separate GridHyperLinkColumn. The "Student" column (obfuscated) is a standard GridBoundColumn.

Any help is appreciated....

Issue with ShowContentDuringLoad

Hi,

I've added ShowContentDuringLoad="false" to my otherwise functional RadWindow (see below). Now the loading dialog is displayed but never goes away. I can see in Fiddler that the request completed successfully with a 200 response. Do you have any idea why this is happening? The window loads correctly if the ShowContentDuringLoad attribute is either set to true or removed.

Thanks,
Joe

--------------------------------
      <telerik:RadWindow ID="ViewRRDialog" runat="server" Title="View PDF Report"
        Height="550px" Width="800px" ReloadOnShow="true" Modal="true"
        Skin="WebBlue" VisibleStatusbar="false" ShowContentDuringLoad="false">

RadButton demo of embedded icons

Hi, on http://demos.telerik.com/aspnet-ajax/button/examples/overview/defaultcs.aspx the link under Functionality to Embedded icons seems to be correct, but you get redirected to the documentation page instead of the demo page. The same happens if you click the link at the bottom to the demos page on the documentation page.
