[Solved] Accessing cell template and edit template in code behind

[Rajagopalan]

Hi,
We have a requirement where in in radgridview data column's cell template we have set the collection's property and in edit template, we have a combobox.  Now, based on the radgridcombocolumn which is nothing other than the previous column selection, i have to show the values in the edit template combobox.  If I select some values in the edit template combo box, it wont set because I have applied a textblock and bind the value to some property. 
In order to change the property of the textblock, I have to access the same in code behind and set the selecteditem value of the combobox.
Kindly help.

{

 

 

RadComboBox objTempRadCombo = sender as RadComboBox;

 

objTempRadCombo.ItemsSource = StateCollection;

objTempRadCombo.DisplayMemberPath =

 

"name";
//HOw do I set the textblock to the selecteditem of this combobox here?

Hi Rajagopalan,

Your requirement seems to totally fit the GridViewComboBoxColumn purpose. I was wondering why do you avoid using it .

Now on the issue :

To have things working correctly you need to :
1. Bind the SelectedValue of the combo to the property you need to be edited
2. This property should raise the PropertyChangedEvent form the INotifyPropertyChanged interface.
3. Then the TextBox should be also bound.

If you have these 3 conditions, things should be OK.
As alternative - you can just use the Combo column , as it does pretty much the same.

All the best,
