Model Binding: SelectMethod defined in a Business Object.

[Scott]

I am trying to use the ASP.NET 4.5 Model Binding features of RadGrid in version 2013.3.1114. My SelectMethod is defined in a Business Object. RadGrid throws an exception indicating that it cannot find the method on the page.

I have implemented the OnCallingDataMethods event:

protected void CallingDataMethods(object sender, CallingDataMethodsEventArgs e)
{
    e.DataMethodsObject = new BLL();
}

However, RadGrid still attempts to locate the SelectMethod on the page object. Using the OnCallingDataMethods event of RadComboBox works correctly, so I am surprised that it is not working for RadGrid.

Has this been resolved in newer versions of RadGrid? If not, what are my options?

Hi Scott,

When working with Model Binding and RadGrid, handling the OnCallingDataMethods only for the RadGrid itself will not be enough. In order to get this working you will have to handle the MasterTableView's OnCallingDataMethods event as well:

<telerik:RadGrid ID="RadGrid1" runat="server" AllowPaging="true" OnCallingDataMethods="RadGrid1_CallingDataMethods">
    <MasterTableView SelectMethod="GetProducts"></MasterTableView>
</telerik:RadGrid>

And the code-behind:

protected override void OnInit(EventArgs e)
{
    base.OnInit(e);

    RadGrid1.MasterTableView.CallingDataMethods += MasterTableView_CallingDataMethods;
}

void MasterTableView_CallingDataMethods(object sender, CallingDataMethodsEventArgs e)
{
    e.DataMethodsObject = new TestCustomObject();
}

protected void RadGrid1_CallingDataMethods(object sender, CallingDataMethodsEventArgs e)
{
    e.DataMethodsObject = new TestCustomObject();
}

Hope this helps.
