I am trying to use RadGridView.RowPain. I need an extra header row to show that the columns are categorized:

e.g.


This should be relatively easy, except I don't know how to find out the cell locations for the column headers. Because my cells cannot be moved, I tried adding up the cell widths, I had some success - except when use the horizontal scroll bar.

Please can someone explain how to get the cell locations.

Thanks

Hello:

Our controls do not validate until after the user tabs off, which is the default for binding (OnValidating). However, in the case where the use clicks a save button, validation is taking place after the save event fires. This leads to situations where the changes aren't saved and the user closes the form, losing their changes.

In Windows Forms, you could call ValidateChildren to force the controls to bind to the underlying data object. This doesn't appear to work with Telerik controls.

Is there a way to force changes to commit to the data object before the save takes place? I don't want to change the binding DataSourceUpdateMode to OnPropertyChanged.

Thanks,

Hi there guys

I'm trying to customize the filtering row in a Winform Telerik Grid. What I want is to hide the Filter Icon and only show the text boxes. When a user enteres text in the text box it should apply the "Contains" filter on the column.

I have been using Telerik ASP Net. Radgrid quite a lot and could set the "ShowFilterIcon=false" and on the gridboundcolumn and "AutoPostBackOnFilter=true" to get the desired functionality.

Any hints?

Is automatic DataBinding with a TelerikDropDownButton possible?
When I'm binding a DataSoure to a TelerikDropDownButton does it only shows the first line in the table. 
Must I create manually all items by a function when I load the form or is here an automatic mechanism?

thanks in advance
guy

I need to use two button columns on a grid view and to pop up win forms when each button is clicked.
On the cell click event other columns are identified but not the button columns,

How can I fix this??
Any help will be highly appreciated.

Hello.

According to this thread, I want to ask if radgridview support transposing?

Thanks in advance.

Good afternoon Telerik :)

There seems to be a problem with form closing events when using RadDock with MDI forms and AutoDetectMdiChildren. When I call the Close function of a docked form, the Closing event of the form is call twice. This does not happen when I close the form from the RadDock control (for example, with middle click on the tab document). This is a link to a project that demonstrates this problem.
This behavior breaks our data checking process (unsaved or invalid data etc).

Additionaly if someone cancels (setting the e.Cancel property of CancelEventArgs to true) the closing process on the second fire of the event, the form will close but the docking document will remain open.

I am using the latest trial release (Q3 2010).

Thank you in advance for the answer Telerik team :)

Hi,

I think there is a possible bug in MasktedTextBox when you copy paste. here is the scenario to recreate this.

have a MaskedTextBox with masktext as 00-00-00 (Sort Code) with Type as Standard.

run the application and you will see the text is now defaulted to 00-00-00.

1. Open notepad and type 222222 (6 chars) and select the text and right click and copy.
2. block/Select all the maskedtext in the app,
3. right click and select paste option.
4. you will see the text pasted in the masked textbox and
5. Tabout using a tab key and the copied text disappears.. and defaults to 00-00-00. where as the values should have been 22-22-22.

Note: this doesn't occur when you do ctrl+v and if you do ctrl+v first time then right click option works fine here after.

please advice.

Khizar

Hello!

I have a couple of issues with Excel-Like Filtering in RadGridView v.2010.3.10.1215.

1. The filter dialog title is “RadGridView Filter Dialog [<column>]”. Is it possible to customize it?

2. If both selections in the filter dialog are “No filter”, the following exception is thrown:

Object reference not set to an instance of an object.

Is it possible to catch it?
