setting enumerations in combobox Cell Element seams to crash the grid

Hi I am using the Gridview, to display some data. I have a tax filing status column, which I am giving it the values of the combo box from an enumeration, like the following.

(gridViewTemplateTaxData.Columns["FilingStatus"] as GridViewComboBoxColumn).DataSource = Enum.GetNames(typeof(TaxFilingStatus));

When I the user changes the value in the combo box, I change the bound data of the grid. Then I refresh the templates of the grid.
Some of the time this works fine, but often enough, I get the following exception.

Object reference not set to an instance of an object.

Telerik.WinControls.UI.GridComboBoxCellElement.SetContent(). I walked through the code that I have in the cell value changed, and there is no issues there. Am I using the ComboBoxColumn wrong ?

Selecting radGridView row

Hello, Happy Holidays!

I have a variable SelectedIndex that is bound to the index of the "clicked" row. I use SelectedIndex like this: radGridView1.Rows[0].ChildRows[SelectedIndex].IsCurrent = true; but this doesn´t work, it highlights the first row. If I use radGridView1.Rows[0].ChildRows[1].IsCurrent = true; for example it works! anyone can give me an idea?

thanks in advance,
Michael

Hiearchical grid

Hello,

I have one problem that makes me crazy. Can anyone help?

Problem:

I have a tree structure that I wanted to bind to RadGridView, something like this:

public interface IGridViewZadanka

{

Odbornost Odbornost { get; }

int IDZad { get; }

string ZadankaInfo { get; }

IEnumerable<IGridViewMetoda> MetodyView { get; }

}

public interface IGridViewMetoda

{

string Test { get; }

string Izolace { get; }

string Postup { get; }

string P { get; }

string Zadani { get; }

string Odecet { get; }

string Vysledek { get; }

string Stav { get; }

bool Tisk { get; }

string V { get; }

string Popisek { get; }

int IDZad { get; }

int IDZadMet { get; }

int? IDParent { get; }
Odbornost Odbornost { get; }

}

I want to bind this structure to two-level hierarchy grid with one feature: second level will contain 2 (or more in future) tables that depend on field Odbornost (detail table for Odbornost are slightly different – for Odbornost MB would be nice to use self-referenced hierarchy, but for Odbornost TS would be nice to use only flat view of data) and only one corresponding detail will be visible.

For example:

+ (IGridViewZadanka) IDZad=1, Odbornost=TS,…

- (IGridViewMetoda) IDZad=1, Odbornost=TS,…

+ (IGridViewZadanka) IDZad=1, Odbornost=MB,…

+ (IGridViewMetoda) IDZad=1, Odbornost=MB,…

- (IGridViewMetoda) IDZad=1, Odbornost=MB,…

+ (IGridViewZadanka) IDZad=2, Odbornost=TS,…

- (IGridViewMetoda) IDZad=2, Odbornost=TS,…

From examples in http://mono.telerik.com/Grid/Examples/Hierarchy/TwoTablesAtLevel/DefaultCS.aspx and http://www.telerik.com/help/aspnet-ajax/grid-several-tables-at-level.html and http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/twotablesatlevel/defaultcs.aspx I know that this is possible, but I am unable to do it. Can anyone help me and provide me some example (in C# for win form)? I would appreciate it.

Gant Chart and View

I'm wonderingif Radscheduler supports Gant Chart. Also, there is any way I can switch the hours of the day to horizontal instead of vertical? I've included a screenshot of what I want to accomplish with scheduler. Also, this is for Winforms and not ASP. Thank you in advanced

RadMarkupEditor

My company has assigned me the task of updating one of our older programs by adding a Rich Text Editor into one of the comment fields. In order to achieve this with our Q3 2009 Telerik controls, I created a button that opens a RadMarkupEditor dialog.

My only concern is -- how can I change the title of the dialog?
