Hello,

I have a RadWindow. The window contains a table with two rows: the first row (sigle column) contains a RadTabStrip and the second (two colums) contains a checkbox and a button. Each TabStrip contains a RadTreeView:


I want the content of the first row to autoresize if the RadWindow is resized and the second row to remain the same.

I've tried setting the row height to 100% but with no result.

Hello,

I have the AllowCustomEntry set to true and I have the following scenario:
If the new Entry is an Email (has an email format) then add it normally, if the new Entry is not an email then
Check if the New Entry Exists in the DataSource/ENtryCollection, if it Exists then Do Nothing, if it doesn't exist
then I need to set the Background Color of the new Entry to Red.

This is what I have so far:

I have the following custom sort handler in a radgrid.

For most columns, this is fine.  But on occasion my datafield name is different than my object field name.

ie.  a column with the following works
col.DataField = "Id";
col.UniqueName = "Id";
col.SortExpression = "Id";

but this column fails with error:

No property or field 'OnDate' exists in type 'EvidenceEntryGridItem

col.DataField = "DateEntered";
col.UniqueName = "DateEntered";
col.SortExpression = "OnDate";

This happens after the NeedDataSourceHandler finishes, so I am successfully getting results, and getting them into the grid.  It's something internal to the grid that is failing.


NeedDataSource is pretty straight forward (it is in VB)



Am I missing something in my sort handler?

Hi,

I have a table implemented using radgrid and I have some linkbuttons (add, edit delete) on the top, all these buttons are functional,
however, I wonder if it is possible to make edit and delete not clickable or disabled or invisible if none of the row is selected?

I have a scenario where am processing files completely via Ajax with a custom handler.  As a file is uploaded and processed on the server, it is referenced in another area/control on the page where it can be deleted or otherwise affected.  As such, I want to remove it from the collection of files shown.

I attempted to do this in the fileUploaded event.  I traverse the files array returned from getUploadedFiles, compare the file names, and if it's the same, call deleteFileInputAt.  Unfortunately, this isn't working.  (I'm testing with multiple files of various sizes so that they finish in a random order).  It appears that the array of files returned from getUploadedFiles only includes the actual files that have been completed, so when I attempt to use the index from that array, it doesn't match the index I need to pass to deleteFileInputAt.

In the fileUploaded event handler, I would like a definitive reference to the file related file input, and then have a mechanism to remove that specific input.

Is this possible?

Here's some background in case there's another better way to do this...

I have a list of "things" on a page.  I have a window that I can open that allows me to add a new thing, and optionally upload file attachments for the thing.  I also open the window so the user can edit existing things and manage the attached files.  I would like the mechanism for deleting the files to be the same regardless if this is a new thing or an existing thing.  My plan was to have a list of uploaded files with a delete button for each.  The user could then just click the delete button to delete any attachments.  In order to be consistent with existing things and new things, I wanted to add a file reference to the list of attached files as soon as the file completes uploading, and at the same time, remove the file from the list of files shown in the AsyncUpload control.  Again, is this possible?

Thanks!

Q1 2013 (released Feb 20, 2013) brings a significant performance improvement to Telerik’s Grid for ASP.NET AJAX . Till Q1 2013, every hidden column (Visible=”false”) from the control used to store its cell data into the ViewState of the grid. However, in scenarios with many hidden columns or one hidden column bound to a large database this might have negatively impacted the performance of RadGrid.

We improved this behavior, so that the ViewState of RadGrid holds only the visible column data. However, if somewhere into the code you depend on the hidden column’s cell text which now will be empty (set to “ ”), this performance improvement will introduce a breaking change for you.

To resolve the issue for individual columns, you can replace the Visible property of the column with Display in order to get the corresponding value of the hidden column’s cell.

However, if the project is significantly large with many hidden columns or you want all of your invisible columns to hold their data, you can revert to the old behavior by setting the following property in the web.config file of the application:

When the grid detects this setting, it will bind all invisible columns and put their values into the ViewState.

Please note that the BindGridInvisibleColumns property was introduced in 2014 Q2 SP1 (version 2014.2 724). With any previous versions, setting that property will not have any effect and you will still receive the previous behavior.
