Hi Experts,

I have a Silverlight DataGrid and, it is binded with a dataSource.

SQL

<data:DataGrid x:Name="SLDataGrid" RowStyle="{StaticResource MyDataGridRowStyle}"  
            </data:DataGrid>

In code

C++

SLDataGrid.ItemsSource=List<data></data>

Fine.. Now based on the value of "Data.IsReadOnly"(IsReadOnly is a Boolean Field), How I can set those particular Rows as ReadOnly in Silverlight DataGrid.

Thanks and Regards

ArunKumar

It is not possible to set entire rows to readonly in a datagrid. You can however set the control containing your datavalue to readonly; just bind the ReadOnly property to your rowvalue's readonly property.

[edit] hmm, I do not seem to be able to attach the zip file with the solution in it, can you download it from here?

Thanks Perry Bruins for your reply. But Perry Bruins, we are defining only columns in Silverlight datagrid. We can make that columns as readonly no problem. But how it is possible in the case of only certain rows..??(Since we are binding Datagrid with some item source).

Hi Arun India,

The datagrid builds the row based upon the control definition used for that column. Any binding to the template for that control will be applied for each row.

So, you must use the template form of the column definition in order to be able to specifiy which control you will be using. Part of that template will then be also the binding to your readonly property.

Hi Perry Bruins,
That means we can make a column(Controls like TextBlock, CheckBox etc.) as Read only, not the row.. right...??

Perry Bruins 25-Mar-11 14:34pm

Hi Arun India,

well, what happens is that during binding of your datasource, for each row, the template definition of the column is used to create the control that shows your data for each column. At that time, it will also use the binding of the readonly flag. I have no example handy right now, but if you really need it, I can try to put up one during the weekend.

Thank you very much Perry Bruins for you valuable time. It will be very helpful for me, if you put the example.. Once again Thanks for your valuable answer.

Good Luck
Arun

Here is the example. Note the usage of the template columns in XAML, specially the binding to the IsEnabled property of the controls. Hope this helps you enough.

I do not seem to be able to attach the solution zip, here is a public download link to it. Hope this helps!
