[Completely new with Telerik]
Hi

I have a Category column in Employee Table as of type GridViewComboBoxColumn and i have assigned a datasource to it.  
The values of this column can be "Male" or "Female". The datasouce contains these two values.

While adding new record I want to pick up 1st available value in datasource as default selected.

How can i do this?

 

Regards

Raghu.

Hello Lee,

Thank you for the question. Currently RadGridView does not support setting default values for combo box column. However, you can implement the desired functionality by creating custom editor. Please, consider the following code:
        void radGridView1_EditorRequired(object sender, EditorRequiredEventArgs e)
        {
            if (e.EditorType == typeof(RadComboBoxEditor))
            {
                e.EditorType = typeof(CustomComboEditor);
            }
        }
  
  
      
class CustomComboEditor : RadComboBoxEditor
    {
        public override void BeginEdit()
        {
            base.BeginEdit();
  
            RadComboBoxEditorElement editorElement = this.EditorElement as RadComboBoxEditorElement;
  
            if (editorElement.SelectedIndex == -1)
            {
                editorElement.SelectedIndex = 0;
            }
        }
    }

Do not hesitate to contact me again if you have any other questions.

I was curious to know if there has been an update to the control in order to assign a default or "first" item in the bound gridviewComboBoxColumn?

Thanks

Hello Bob,

Thank you for writing.

In the latest version, the combo column uses RadDropDownList editor and selecting a default item for it will not require overriding the whole editor. You can just use the CellEditorInitialized event handler:
void radGridView1_CellEditorInitialized(object sender, GridViewCellEventArgs e)
{
    RadDropDownListEditor editor = e.ActiveEditor as RadDropDownListEditor;
    if (editor != null)
    {
        RadDropDownListEditorElement element = editor.EditorElement as RadDropDownListEditorElement;
        element.SelectedIndex = 1;
    }
}

I hope this helps.

 

All the best,
Stefan
