Hello!

I have a problem with custom sorting in the latest WinForms RadGridView (2010.2.10.806). It worked well with version 2009.3.9.1203. I use Visual Studio 2008 with .NET 3.5.

The code snippet is very simple:

01.foreach (GridViewDataColumn column in grid.Columns)

02. column.CustomDataOperation = CustomDataOperation.Sorting;

03....

04.

05.void grid_CustomSorting(object sender, GridViewCustomSortingEventArgs e)

06.{

07. MyItem item1 = grid.Rows[e.RowIndex1].DataBoundItem as MyItem;

08. MyItem item2 = grid.Rows[e.RowIndex2].DataBoundItem as MyItem;

09. ...

10.}

When the grid column header is clicked, the System.StackOverflowException occurs in grid_CustomSorting at the point where e.RowIndex1 or e.RowIndex2 is accessed. Moreover, it occurs even if we have

1.void grid_CustomSorting(object sender, GridViewCustomSortingEventArgs e)

2.{

3. int ind1 = e.RowIndex1;

4.}

The second problem is that e.RowIndex1 can be negative even when the e.CellValue1 contains a good value.

So, how should I sort the grid by underlying data using my custom logic?

Thank you.

Dragging RadGridView from Data Sources Window Causes Error

I am using Visual Studio 2010 Professional version 10.0.30319.1 and Telerik Rad Controls for WinForms Q2 2010 SP1 (2010.2.10.806). I have created a new Rad Controls Windows Forms Application.

I added a new data source to the Data Sources Window. If I try to drag a table from the Data Sources Window with the control type set as the default RadGridView control, I get the following error

"An error occurred while performing the drop:
Control 'RadGridView' cannot be used to bind to a table"

If I select the standard Microsoft DataGridView, it works fine.

Any ideas why the RadGridView does not work?

Thanks

Add RadGradView as a control to DataSets

hi,

well we're new to radControls and are testing its abilities in a trial version.

the most important thing we need, is to use RadGridViews for our datasets. When you browse the data sets listed in the data source window, you can set a control as default for your tables within your datasets. I can find a lot of RadControls in it, but not the RadGridView Control.

I've also checked another data types, but RadGridView is not listed anywhere. why? is it possible to add this control manually? or is there any better/easier possibilities?

best regards,
A.V.

SelectedIndexChanged in GridViewComboBoxColumn

Hi Telerik Team,

I am struggeling with an issue, Actually I have a GridView in wich I have 5 different columns. One of these columns is a GridViewComboBoxColumn. My issue is I need to get the selected value of this combobox and set that value into the next column.

Is that possible to handle SelectedIndexChanged event of GridViewComboBoxColumn and also can we handle ItemDataBound event of GridViewComboBoxColumn.

Please help,

Many thanks

Problem with RadGridView Filter with CheckboxColumn

Hi,

I have dataset which includes one boolean field too. When this dataset is set as the datasource for radgridview it works fine and user can edit checkboxes.

But when the fiter is turned on, I can check/uncheck any checkboxes for the first time but in the second approach the grid automattically scrolls up and other row is checked/uncheked.

To reproduce this problem, have a dataset with bool and text field. Fill the dataset with about 50 rows so that radgridview has to show up the scroll bars. After binding this dataset :
scroll to the bottom of the gridview,
check the last one, it will work
try to check last but one, grid will scroll to top and another random checkbox is checked.

Is this a bug or I am missing something?

Thanks
