SelectedTabIndex on Page Load

When I set the SelectedTabIndex on Page Load it does only work the first time the page is loaded. On the following postbacks it is not correctly handled.
However, if I add the same logic in the OnPreRender, it works correctly.

Is this by design? or is it a bug?

Buggy/partial display with custom skin

Hi,

This week I test free trial Telerik ASP.NET Q2 2010 on visual studio 2008.
I have to create a custom skin, that is very important for my business. With embedded skin all is ok but when I tried to use custom skin from visual style builder, problems begins. In this thread I joined in attachment the result on firefox (same on IE) and my custom skin is based on forest original skin with no modification.

Big green place in the display is rad editor!

Thanks to look at my code.

Get MasterTableView Height/Row height dynamically after data is bound

Hi,
Could anyone please tell me - How to get the following dynamically in code behind (i was able to set values for these ...)
    1. RadGrid's each row height (Row height of each row in MasterTableView)
    2. Height of MasterTableView .

Why I need this:
One column in my radgrid is description. It can grow to huge size. I cant parse and give tool tip as I need to print and export(it exports/prints only the data on the grid)
So I gave scrolling to grid even though pagination is there .
Since the description can grow and shrink the following code inside DataBound Event is also not working
           if (gridItems < 4)

{

grid.ClientSettings.Scrolling.ScrollHeight = Unit.Pixel(gridItems * 28);

}

So I tried instead of hard coded "28", the following

if (grid.MasterTableView.Height.Value >= 150)

{

grid.ClientSettings.Scrolling.ScrollHeight = Unit.Pixel(150);

}

else

{

grid.ClientSettings.Scrolling.ScrollHeight = grid.MasterTableView.Height;

}

But grid.MasterTableView.Height is always 0.0 :(

Export to PDF - cutting off data

Hi,
We've got a RadGrid that users need to be able to add/remove columns, then export to pdf. The issue is that if there are too many columns selected, it truncates the rightmost information. Is there some way to tell the export function to either create additional pages with the extra data or compress the data to fit the page width that is set?
Thanks,
Dan Norton

Clear RadListView on client-side

Hi,

What is the way to delete all items from RadListView on client-side? I suppose I can use deleteItem() method but it requires an index so I need to get at least items count somehow.

I also have tried to use get_clientDataKeyValue() method but it doesn't return what I expect (array of actual items).

Thanks,
Andrey

Inconsistent alignment in RadGrid column



Hello,



We are experiencing strange alignment problem in one (numeric) rad grid column. Please see attached picture.

Given HorizontalAlign="Right"  and AllowScroll="True", the alignment changes after PageSize rows.  
How can we work around this?
