I am fairly new to using Telerik. In my latest project, it has been requested that I create a left-hand side dashboard (like a sidebar). We are hoping that it can be clicked in and it will slide out and back in when the user is done with it. Does anyone have any suggestions on the best control to use? I discovered the RadDock, but I'm not sure if that's the best solution. Thanks!

Keeping scroll position of details after postback

Hi,

I've implemented the example suggested in the following thread:
http://www.telerik.com/community/code-library/aspnet-ajax/grid/separate-scrolls-for-inner-tables-in-hierarchical-grid.aspx

And I was wondering if there was a way to keep the scroll position of the <Div> for the details?
My Details has several controls that cause postbacks and each time the positionning is reset.

Thanks

Cross page viewstate problem

I have two pages both with dynamicaly declared grids.
Page A posts to page B. But this page throws an error because the grid does not match the viewstate (of the previous page).
How can I solve this problem?

[Solved] Custom Delete Confirmation with parameters

Is there a way to create a custom delete confirmation using RadWindow that would allow me to ask the user about delete options when performing the delete? I need to be able to ask the user when deleting a record if the related records should also be deleted, or unlinked.

Custom drag handle on titlebar

I am trying to see if there is a way to create a custom drag handle on the title bar. I am trying to to do this, because I have a textbox and a search button on the titlebar as shown and I don't want to put the dock in non-draggable mode to search type in the textbox and click the button. One way I accomplished this is by adding some javascript to disable the draggability when typing in the text box and hovering over the button. However, this is not foolproof. So, I am wondering if there is a better solution to this without having a button like you all do in your examples to put the dock in non-draggable mode. Also how do you actually center something in the titlebar, because when I added the custom template my title disappeared!

raddatetimepicker not working after upgrading to asp .net ajax

I am in the process of upgrading the radcontrols to asp .net ajax.
The raddatetimepicker is causing problems with this.
the error i get is
Value of '1/1/0001 12:00:00 AM' is not valid for 'SelectedDate'. 'SelectedDate' should be between 'MinDate' and 'MaxDate'.
Parameter name: SelectedDate

i have three options to show a document
1) show document
2) hide document
3) show for date range (this one take a show start and show end date)

for the first two options we are saving null in the database and when this value is returned it throws the error mentioned above. it works fine for the third option.

any ideas as to how to return a null value for a raddatetimepicker when the value in the database is null??

Thanks!
