Allow null or no data insert for a item int32

[Pierre]

Hi everybody,

I have some simple problem during my data insertion. I use one item grid as int32 and the data is mandatory by the grid. How to allow my user to no insert anythink if no need ? Actually is returning one error if no data added in this cell.

Thanks for your tip.

Hello Pierre,

I am not quite sure about your scenario. I guess you have one mandatory field in grid which cannot be left as blank and want to notify the user about this. If that the case you can add the RequiredFieldValidator control to that field. Please refer the following documentation which illustrates on how to add validator.

Hope this helps, feel free to ask if you have any more queries.

Hi Princy,

It's not mandatory in my base but the grid is demanding the item. How i can allow null values during automatic Edit/Insert?
This discount column is null if user not need. Only add to one cell no others. Actually everytime need to add zero.

 <telerik:GridBoundColumn UniqueName="Days_promo"  HeaderText="Discount(%)"
                        DataField="Days_promo" DataType="System.Int32">
                        <ItemStyle  Width="70px" />
                    </telerik:GridBoundColumn>

 
Thanks.
