Page with Telerik controls loads very slowly

Hi,

My pages are loading very slowly.
My pages are containing textboxes, RadCombo, RadGrid and etc.
When I run this page using VisualStudio or in IIS, it will take more time to load.
This performance issue is only for pages with Telerik controls.

Thanks,
Sabarish.

RadGrid + Popup edit mode + RadNumericTextBox compatibility issue?

I am using a RadGrid with Edit Mode = Popup and a user control edit form. The edit form contains a RadNumericTextBox. On postback, the value of the RadNumericTextBox is empty. Why?? If I replace it with a normal <asp:TextBox> then everything works fine, but the RadNumericTextBox doesn't seem to realize that I entered anything in it. Text and Value properties are both empty. Is this a known issue and if so, what's the workaround?

[Solved] GroupsDefaultExpanded="false" Causes Export to be Blank

I have a Grid with a Group setup. The grid has a CSV export button, uses an SqlDataSource, and is not ajaxified.

When GroupsDefaultExpanded="true" the export has all of the data but when GroupsDefaultExpanded="false" the export is empty.

How can I force the grid to export the data even though it begins with all groups collapsed?

Invalid object passed in, ':' or '}' expected.
Unrecognized escape sequence.
Unterminated string passed in.

Do you have any idea on what happens here and how to fix this?

[Solved] Having problems dragging RadTreeNode into RadDockZone populated with RadDocks

I'm dynamically creating RadDock's within a RadZone (vertically). In order to add another RadDock in the RadZone, I am dragging a RadTreeNode into the RadDockZone. The problem I am running into is that if I drop a RadTreeNode on a RadDock that has been dynamically created in the RadDockZone the OnNodeDrop event is not fired.

I've have verified that OnClientNodeDropping is still called regardless. The only difference is that the server side event is not fired when dropped on the RadDock, which is in the RadDockZone....but the server side event is fired when dropped directly on the RadDockZone.

Has anyone run into this issue before?

Upgrade to 2009 Q3 question

I couldn't find any documentation for upgrading to 2009 Q3. Do I need to uninstall the previous version first, as I only need the current release? Are there any gotchas in doing this? I just want to make absolutely sure before potentially wasting my dev environment

That took some time to me to find the reason of the problem (my current grid is quite complex)
User just need to add empty ItemTemplate. However, it was not easy to find the reason

<telerik:GridTemplateColumn Visible="false">

<ItemTemplate>

</ItemTemplate>

    <EditItemTemplate>

            <asp:DropDownList ID="ddCategory" Runat="server" CssClass="GeneralDropDownList"></asp:DropDownList>

    </EditItemTemplate>

</telerik:GridTemplateColumn>

formview with radgrid

hi, i just downloaded your controls and they look wonderful, so i will make tests to finalize my decision to purchase.

i am trying to do the following,i dont want to use radgrid edit functions, i want to add a rad grid with records and i want to click edit button then it will show form view with the records data so i can update or insert a new record, my questions are

-what is the best approach to make edit button?

-best way to pass the record id to the form view without page refresh?

-i want when i click edit to hide the grid and show the form view and vise versa when i update the record to hide form view and show grid view so should i add to the button click even a command to make grid.visible = false and form view.visible = true and vise versa ? or should i do that through java script to change the css class for each ?

-when i finish the edit and go back to hte grid i want the edited row grid to be highlighted ?

- best approch to ajexefy the whole process?

thx in advanced
