Hi,
When you set the AutoGenerateColumns property of RadGrid to true, the RadGrid control generates a separate column for each data field in the control's assigned datasource. Based on the DataType of the field, the grid control will generate the respective column types :
GridCheckBoxColumn displays a check box to represent a Boolean value. You should bind this column type to a Boolean field by setting its DataField property. If this column type is bound to a data value that is not Boolean, the grid throws an exception.
Therefore, after you have auto generated columns, I would suggest you change your datasource to output a boolean value rather than an integer. The RadGrid will automatically pick this up and enable checkbox for edit.

Thanks for the reply.
I already converted my datasource to Boolean but now I have another issue. I want to select/deselect checkbox from those Autogeneratedcolumns but those are disabled by default. Please tell me the right way to enable Autogenerated checkbox.

Hi Dev,
It is the default behavior of the GridCheckBoxColumn. When the grid is in browser mode, or if the column is read-only, the check box is disabled. When the column is editable, the check box is enabled. Check out the following document to understand better about the various columns supported by RadGrid.

Hi Dev,
I guess you want to have the Grid in edit mode. You can set the AutoGenerateEditColumn property of the RadGrid to true.
ASPX:
Please try and let me know if any concern.
