I have  abound gridview that i have added a checkbox column to as the first column.
i cannot check any checkboxes in any row, only able to check the headercheckbox which selects all checkboxes of every row.

Dim checkboxcolumn As New GridViewCheckBoxColumn
checkboxcolumn.DataType = GetType(Integer)
checkboxcolumn.Name = "SelectedColumn"
checkboxcolumn.FieldName = "Select"
checkboxcolumn.HeaderText = "Select?"
GV_Assets.MasterTemplate.Columns.Add(checkboxcolumn)
checkboxcolumn.EnableHeaderCheckBox = True

 

Hello, Donovan,  

The GridViewCheckBoxColumn.EditMode property controls when the value of the editor will be submitted to the cell. By default, (OnValidate), the value will be submitted only when the current cell changes or the grid looses focus. The other value, (OnValueChange), will submit the value immediately after the editor value changes. I would recommend you to set the EditMode property to OnValueChange. Thus, the cell's value will be toggled as soon as you check/uncheck the RadCheckBoxElement.

I have attached a sample project for your reference. Could you please give a try and see how it works on your end?

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
