GridViewComboBoxColumn (RadGridview for Winforms)

[Shridhar]

Hi,

I am using the "GridViewComboBoxColumn" in the radgrid win forms. I have created a type of GridViewComboBoxColumn and added it to radgridview.

            gridViewDDLCombbxColumn2.FieldName = "Data Base No";
            gridViewDDLCombbxColumn2.Name = "DataBaseNoCombo";
            gridViewDDLCombbxColumn2.HeaderText = "Data Base Num";
            gridViewDDLCombbxColumn2.DataSource = GetUserGrpData;
            gridViewDDLCombbxColumn2.DisplayMember = "DBNumber";
            gridViewDDLCombbxColumn2.ValueMember = "UserGroupID";
            this.radGridViewUserGroup.MasterTemplate.Columns.Add(gridViewDDLCombbxColumn2);

I am facing an issue when setting a default value or value from database to GridViewComboBoxColumn and while updating also I am not able to read the selected value from the GridViewComboBoxColumn.

For E.G:
this.radDdlDn.SelectedValue = currentRow.Cells["UserID"].Value;
The above statement can be used to assign the value to radDropdownlist.

String strddlValue=this.radDdlDn.selectedItem.Text
The above statement can be used to read the selected value from radDropdownlist.

Similarly how can we  perform the same operation with GridViewComboBoxColumn in radGridview

Thanks in advance
Shiva

Hello Shiva,

Thank you for writing.

I am not sure I understand your question completely, but I will try to give you some general information on setting and retrieving the value of a cell and the text displayed.

To get the value of a cell in a GridViewComboBoxColumn, you should use the following regardless of the column type:

object value = this.radGridView1.Rows[indexOfDesiredRow].Cells["Name of column"].Value;

To get the text that is displayed for that value you can use the following:

GridViewComboBoxColumn comboBoxColumn = this.radGridView1.Columns["column"];
string text = comboBoxColumn.GetLookupValue(this.radGridView1.Rows[indexOfDesiredRow].Cells["column"].Value);

If this is not what you were asking for, I would kindly ask you to send some more details on your case. If you describe the whole scenario you want to implement, I will be able to better understand what you need and give you an adequate response.

I am looking forward to your reply.

All the best,
