GridButtonColumn CommandArgument Parameter

[Erich]

Hi, I'm trying to pass a parameter in the GridButtonColumn's CommandArgument and CommandName field.  From what I can see in the examples, I should be able to just put in the field, like this....  CommandArgument="Part_id", however, it does not seem to pass the param back to the code behind.  I'm using the RadGrid1.ItemCommand event handler and it kicks off that event just fine.  Here is the button and the code behind and the error....

 

<telerik:GridButtonColumn ButtonType="LinkButton" HeaderText="Additional<br />Process" CommandArgument="Part_id" CommandName="Part_id" Text="View" UniqueName="lnkPartID" DataType="System.Int32"></telerik:GridButtonColumn>                

 

Private Sub RadGrid1_ItemCommand(sender As Object, e As GridCommandEventArgs) Handles RadGrid1.ItemCommand
        Dim partID As Integer = CInt(e.CommandArgument)
        code....code.... .code....
End Sub

Error...

Input string was not in a correct format...

The value is an integer.

Many thanks,

-Erich Neubert

Hi Erich,

The button column has the following property:

<telerik:GridButtonColumn ... DataTextField="OrderID">

But for passing the field values as command argument, you should use GridTemplateColumn:

<telerik:GridTemplateColumn DataField="ShipCountry"
    FilterControlAltText="Filter ShipCountry column" HeaderText="ShipCountry"
    SortExpression="ShipCountry" UniqueName="ShipCountry">
    <ItemTemplate>
        <asp:LinkButton ID="LinkButton1" runat="server" Text="View"
            CommandArgument='<%# Eval("OrderID") %>'></asp:LinkButton>
    </ItemTemplate>
</telerik:GridTemplateColumn>

I hope this will prove helpful.

Thank you, I eventually got there.  How to I put in a feature request?  And also, under the documentation, where would I have found the information about what properties could be databound?  

 

Thanks again.

Hello Erich,

You can find the public feedback portal here:
https://feedback.telerik.com/Project/108

And although there is no specific section dedicated just for the databinding properties, you can check the following table:
