Saving gridview with combobox columns giving null values

[Sree]

Hello Telerik Team,
 i have some issues with the comobobox column of radgridview for winforms

here is the below code

                GridViewComboBoxColumn colLithography = new GridViewComboBoxColumn();
                colLithography.DataType = typeof(string);
                colLithography.DataSource = dt; // dt is having only one Column called Name
                colLithography.HeaderText = "Lithography";
                colLithography.ValueMember = "Name";
                colLithography.DisplayMember = "Name";
                colLithography.FieldName = "Name";
                //colLithography.DataType=
                this.rGVPP.Columns.Insert(2, colLithography); // rGVPP is Radgridview

Above code perfectly added the values to the combobox

but now i want to save the gridview data to database,


So in Btn_Save click i am reading sending the gridview values to a query like below, observe the debug at break point which is the code
and in the quick watch window the value is null, throwing exception here

but my grid having values in all the cell, when i try to read the value of a particular cell of combobox column, its giving null value.

Please help me.

Hi Sree,

You can get a cell from the Cells of a row passing the Name property value of its column rather than the name of the column instance. I can see that there is no Name set for your column, so you need to set one. Considering the column definition from the beginning of this article we would take the cell by Cells["SupplierColumn"]. 

I hope this helps. Let me know if you have additional questions.
