radgrid scolling

[Sylvain]

Hello,
 
I have a radgrid that is paged and i have enabled scrolling, with 3 frozen columns.

I have three problems:
1) I would like to disable vertical scrolling. The user of my grid can set the page size to a number of rows and I would like the proper number of rows to be shown, without vertical scrolling. Can this be done?
2) It seems that the column widths are not scrolled at the same time as the columns are when using horizontal scrolling. By this I mean that when columns are scrolled, the size that they will take is the size of the original column that was showing in that spot before the scrolling took place. This does not look good and reduces the amount of data I can show in the grid at the same time.
3) As soon as I enabled horizontal scrolling, a number of columns on the right are missing and can't be scrolled to. If I disabled horizontal scrolling then they reappear and I can scroll to them using Internet Explorer's horizontal scroll bar.

An alternative for me would be to use the default IE scrolling, which fixes problems #1,#2 and #3, but this prevents me from freezing some columns and also the grid displays a vertical line in middle of the column that is at the right of the window.

Regards,

Sylvain

Hello Sylvain,

In order to render merely the horizontal scroll and avoid the appearance of the vertical scroll, make sure that the height of the records in the grid does not exceed the ClientSettings -> Scrolling -> ScrollHeight scroll setting. 

When you are using frozen columns you should set fixed widths for your grid columns (through their HeaderStyle -> Width property) or TableLayout = Fixed for the MasterTableView. Note that the default table layout for the grid with scrolling enabled is auto and this may cause the unwanted effect when you enable the frozen columns functionality.
In order to display all columns when using frozen columns you should increase the Header Style Width of the last column in RadGrid. Thus you should be able to navigate to the leftmost column as expected to see the information in it.

For more information about frozen columns, please review the following example:

I hope this information helps.

I have a RadGrid with some frozen columns. I increased the Header Style Width of the last column in RadGrid, to be able to view all the columns. But this does not work all the time.  I am using RadControls for ASP.NET AJAX Q2 2009. I was wondering if this has been fixed in Q3 version.

Thanks

Hi Shylaja,

The observed problem can occur, depending on the RadGrid width, the columns' widths, and the number of frozen columns. As a workaround, you can try:
- decreasing the widths of the frozen columns
- increasing the width of the last column by a large-enough amount, so that it appears
- increasing the RadGrid width

Let me know if this helps.

All the best,

Hello Pavlina,

I appreciate you quick response.

 I already have those workarounds that you list out.  But I have a RadGrid that is dynamic. The number of columns in the RadGrid depends on the result of a query. I have set sufficient header width for the last coulmn of the RadGrid which works for most cases, but sometimes it does not.

Is adding a dummy column as the last coulmn of the RadGrid, a better solution?

Thanks
Shy

Disable vertical scrolling

Instead of correctly setting ClientSettings -> Scrolling -> ScrollHeight, the vertical scroll can be better avoided using CSS style.

.RadGrid .rgDataDiv
{
    height:100% !important;
}

Thanks,
