I am facing bug with frozen columns. When I use tab key to navigate the grid that has frozen columns, it distorts the cells after frozen columns eventually. You can also see the issue in frozen columns demo.

To create issue: Open frozen columns demo (Controls > Data > GridView > Columns > Frozen Columns example). Increase widths of Phone and Fax columns by 100%. Click on first cell. Now, keep pressing TAB key to navigate forward in the grid. When first row ends, focus goes to first cell of 2nd row. When 2nd row ends, focus goes to first cell of 3rd row, and so on... When focus comes to first cell after frozen column of next row, the cell after frozen column in previous row is distorted.

Let me know if you cannot generate the issue. I also have attached the error screenshot.

Can you please help resolving the issue? When should I expect the bug resolved? Is there any workaround of the issue?

Thank you,

Amit

Hello amit,

Please excuse us for the inconvenience caused. This is a bug in RadGridView and we are doing our best to provide a fix for the very next release.

Meanwhile no descent workaround can be offered.

Thank you for reporting the problem ! I am updating your telerik points.

Hi Nathaniel,

Indeed the fix for this issue was not included in our latest official release. I have just checked the status of this bug and you may download our internal build next week where such behavior cannot be observed.

Please excuse us for any inconvenience caused.

Hello Nathaniel,

Thank you for getting back to us! I hope that our latest internal build will be available for download on Tuesday. You need to add references to the assemblies related to RadGridView, as follows:

Telerik.Windows.Controls
Telerik.Windows.Data
Telerik.Windows.Controls.Input
Telerik.Windows.Controls.GridView

If you need any further assistance do not hesitate to contact us!

FrozenScroll.png

I have a frozen column that is width 200, and TexWrapping="Wrap". I have 30 columns to the right of this frozen colunm where none of the text wraps. I have to scroll to the right to sell all the columns. When the text is wrapped in my frozen colunm it appears fine when the scroll bar is all the way to the left. But when I scroll to the right, the frozen column shrinks and the text is still wrapped but it overlaps and is unreadable.

RadGridView-SL4-AR-26.zip

Hi Nathaniel,

This behavior is expected if the wrapped cell is in edit mode. If you want the text to be wrapped in this case you can subscribe for PreparingCellForEdit event and set TextWrapping to Wrap:

private void playersGrid_PreparingCellForEdit(object sender, GridViewPreparingCellForEditEventArgs e)

{

((TextBox)e.EditingElement).TextWrapping = TextWrapping.Wrap;

}

Another possible solution is to use CellEditTemplate for the wrapped column as demonstrated in the attached project.

Let us know if your case is different.

How do I get around these problem when I download your examples? The microsoft link does not help.

Error 1 Could not load the assembly file:///C:\Documents and Settings\XXXX\My Documents\XXXX\XXX\XXX\RadGridView_SL4_AR_26\Libs\Telerik.Windows.Controls.dll. This assembly may have been downloaded from the Web. If an assembly has been downloaded from the Web, it is flagged by Windows as being a Web file, even if it resides on the local computer. This may prevent it from being used in your project. You can change this designation by changing the file properties. Only unblock assemblies that you trust. See http://go.microsoft.com/fwlink/?LinkId=179545 for more information. RadGridView_SL4_AR_26

Also will there be another Service pack with this fix that was in the May 2nd build?

Hi Nathaniel,

Please, make sure that all of the referred assemblies in the project are not blocked. How to unblock assemblies is described on this topic. Also, you may remove all referenced Telerik's assemblies from the project and add them again.

For the time being we have not planned for Q1 2011 SP2 and the next official release will be till the end of July.

Yordanka,

I too am having this same problem. I think I figured out the pattern however and it has to do with whether the column with the wrapping is a frozen column or not.

If you remove the frozen column count the grid resizes the rows with the wrapping text without a problem. If you put the frozen column count to include columns without text wrapping, it works fine. Now if you put the frozen column count (or even adjust the frozen column line) to include column that has wrapping enabled and the text does in fact wrap, the grid distorts and the rows do not resize to show all the text; in fact if you move the line yourself the rows resize to only show one line of text.
