Hi,

I have a DataGridView with columns as a DataGridViewComboBoxColumn.

VB

Dim cImageCate As New DataGridViewComboBoxColumn
           dTable = FillCombo("SELECT_ON_CODE", "ImageCategory")
           cImageCate.DisplayMember = "Description"
           cImageCate.ValueMember = "ID"
           cImageCate.DataSource = dTable
           cImageCate.DataPropertyName = "Image Category"
           cImageCate.Name = "Image Category"
           cImageCate.HeaderText = "Image Category"
           cImageCate.DefaultCellStyle.NullValue = "Lineart"
           cImageCate.FlatStyle = FlatStyle.Flat
           dtGrdImageDetails.Columns.Add(cImageCate)

While binding DataSource to DGV

dtGrdImageDetails.DataSource = dTable

I am getting Error message as "system.formatexception datagridviewcomboboxcell value is not valid".

How to bind DataSource to DGV which will get the respective values selected in DataGridViewComboBoxColumn Cell

use for loop for combobox understood?

Hi Gaurav,

Thanks for reply.
Is there any other option to fill DGV with DataGridViewComboBoxColumn.
Because use of for loop will lower down the application performance in my case.
because I have editable grid which will interact with the Database.

This error seems like what is been binded to combo box is different from the "ValueMember" and "DisplayMember" fields.
Can you check if the dTable contains these columns?
