Dear Sir,

I wanted to export gridview data into .pdf file. I gone through kb and it tells that you need to create an object of ExportToPDF. Now I cannot find the specified class in the Telerik.WinControls.UI.Export namespace. There is only one class in the given namespace i.e. ExportToExcelML!

I am using Telrik Controls for WinForms Q1 2010.

Thanks,
Divyesh

The title of the thread says it all:

Me.RadGridView.Rows().Cells().Style.BackColor = Color.Yellow

Me.RadGridView.Rows().Cells().Style.BackColor = Color.Yellow

Me.RadGridView.Rows().Cells().Style.BackColor = Color.Yellow

Me.RadGridView.Rows().Cells().Style.BackColor = Color.Yellow

Me.RadGridView.Rows().Cells().Style.DrawFill = True

I understand that the cell element is gone but this code worked last build using the CellElement but not with the new Style object. I would assume there is a way to change the back color of a cell at run-time. Please give me the correct way so my code will work. Thank you.


OK More Info.....

Me.RadGridView.Rows().Cells().Style.ForeColor = Color.Yellow

this works!!! soooo....just maybe this is something you need to fix with backcolor.. :-)

I find it hard to believe there is no current way with the latest version to set the backcolor of cells at run-time, so any code that works I'll take at this point.

hi,
When I edit with GridView when the wizard does not update table
please help..
thankyou

I'm working on an inventory form and one of the (optional) fields is ReplacementDate. Obviously, for equipment that is still in service, there won't be a value for the ReplacementDate. Is there a way for either the RadMaskedTextBox (with a DateTime mask) or RadDateTime picker to handle a nullable DateTime natively, or do I have to use a numeric mask and handle the Validating event?

Hi,

i've just tested a bit and scrolled through one of my several gridviews that i am using in my application and...whooops...
i've got this error message here:

"Object reference not set to an instance of an object."
And this error occured in Telerik.Wincontrols.UI.

Attached you can find the stack trace:

Hi,

Hi all,

Iam using Radgrid in my application which contains Grid view checkbox column and it is added through design.I have set the property as Fullrowselect for checkbox column .I will select the rows through checkbox and I need to get the count of selected rows in the grid when multiple rows are selected.Can anyone provide me the codesnipett please.

Thanks
Prasad.

I would like to have the grid automatically add a new row when the user presses "Tab" from the last cell in the last row of the grid.

This works if the last row of the grid is an "existing" row (meaning the row was present when the grid DataSource was set). However, it does not work if the user is already entering a "new" row.

For example:

1. Grid is displayed with 2 existing rows.
2. Focus is given to the top-left cell in the grid.
3. User presses "Tab" to navigate across the first row (editing data as needed).
4. User presses "Tab" while in the last column of the first row and focus moves to first column of 2nd row (this is good).
5. User presses "Tab" to navigate across the 2nd row (editing data as needed).
6. User presses "Tab" while in the last column of the 2nd row and focus moves to the first column of a "new" 3rd row (this is good).
7. User presses "Tab" to navigate across the "new" 3rd row (editing data as needed).
8. User presses "Tab" while in the last column of the "new" 3rd row - but nothing happens.
9. User gets confused, can't figure out how to add more rows (this is bad).
10. User calls me (this is really, really bad!!)

Any ideas on how to make the grid keep adding more rows automatically?

I have a GridView that has a child template and a relation. I can populate both without an problems at all. When I expand to view the childrows and click/double click one of them I need to open a secondary form that displays some additional data. In order to do that I need to be able to determine the properties of that childrow which was clicked. However, I keep getting the row in the  MasterTemplate... how do I go about this.

I had used a filter in one place in my app and with the latest update it stopped working. So, I looked through the entire solution for WinForms RadControls 2Q2010 and did not see any examples. The one example was commented out without any explanation. This looks like something that could be useful but I need a simple example to get started. Thanks.
