I have a Chart inside an UpdatePanel that is bound to a SqlDataSource. Outside the UpdatePanel, I have a dropdownlist. The SqlDataSource uses the selected value of the drop down list as a control parameter when selecting data that is used in the chart. By itself, this setup is working great. When I change the drop down list value, the chart updates. If the SqlDataSource returns 0 records, the chart shows the EmptySeriesMessage
However, I tried adding a Click event in the code behind. This is all I added:
Protected Sub RadChart1_Click(ByVal sender As Object, ByVal args As Telerik.Charting.ChartClickEventArgs) Handles
End Sub
Now when I change the selected item in the drop down list, everything works fine, but only if there SqlDataSource returns results. If the SqlDataSource has 0 results, then I get a JavaScript error and the chart does not update. The javascript error is PageRequestManagerServerErrorException Object reference not set to an instance of an object.
Can anyone help me? Is this a bug with the RadChart?

Hi
I frequently use RadGrid in the automated edit, delete and 'Add New Record' mode as a very quick
solution to input and edit of data.
However I have not found a clean way of saving today's date in my DateCreated field when a new record is
created using the 'Add New Record' command button, other than a separate database update function after the
RadGrid has saved the other data. This seem to be making what should be a simple job, complex.
Can you tell me how best to do this either declaratively or in code behind in the appropriate RadGrid event.
Thanks a lot for your expertise!

I have been playing around with the color picker and I notice a behavior which doesn't seem logical. When hovering over the pallete, the "preview" color is shown as you hover over each option, however, if you stop hovering over the colorpicker, the last hovered-over color is what is shown in the preview, even if this color was not selected (clicked on). In my opinion, when you move your mouse outside of the area that shows the color pallet, the preview should revert to the currently selected color. If the picker's SelectedColor is not set, then it should display a default ("white" I suppose, or even beter, a box with a line denoting "No Color"). I can't off the top of my head think of any scenario where you would want the preview pane to remember the last color that happened to be hovered over, since, in order for the user to "leave" the pallete, they likely have to hover over colors they don't want to select. Even if there were such a scenario, I would think my example would be a much more natural behavior. Either way, there should be some sort of setting which defines this, and I couldn't find this. Is there any way to prevent this behavior in the current control?

I am having a problem removing the PageSize label and combobox. I stepped through the code and found that:
e.Item.Controls(0).Controls(0).Controls(0).Controls(0).Controls(3).Visible = False
works (sort of)... Then some research online I found that:
e.Item.FindControl("ChangePageSizeLabel").Visible = False
e.Item.FindControl("PageSizeComboBox").Visible = False
Works as well. The problem is that when I click to change the page (with ajax) the code no longer works. I was able to remove using CSS but Something else I am doing is setting a mouse over on each page button. This works, but not with ajax postback. Stepping through the code, I set the tooltip on the button the same for page load and ajax postback but it appears that pager changes do not take affect for ajax partial page rendering. Sniffing the packets I see the update panel updating the radgrid but the <a> tags do not have a title like they do in the original page load.
UPDATE: I turned off Ajax and found that it is NOT Ajax it is postback period.

Hi,
We're evaluating Telerik navigation controls. And want to know if they provide multilingual support, to be used along with variation(multilingual feature) within MOSS 2007.

Hi there
I am using a RadGrid with ClientSettings.Resizing.AllowColumnResize set to true;
However, I have a user who is finding it difficult to position his cursor at the point needed to trigger the "Drag to resize" resizing handle cursor. He is not able to position the cursor that accurately.
I am struggling to work out where to make the changes needed to increase the size of the area in which he needs to hover the cursor so that he doesn't have to be so precise in his positioning. Could anyone please advise me as to the best way to do this?
Thanks in advance
Tim
