Problem in loading the GridViewComboboxColumn.

[SivaPrasad Bevara]

Hi,

I am using 2 RadDomainDataSources, one for loading the RadGridView and another for loading the GridViewComboBoxColumn.

Following is the code.

<telerik:RadDomainDataSource Name="employeesDomainDataSource"
                  QueryName="GetEmployeeDeptDTO"
                  AutoLoad="True"
                  PageSize="10"
                  Height="0" Width="0"
                  SubmittedChanges="employeesDomainDataSource_SubmittedChanges"
                  >
      <telerik:RadDomainDataSource.DomainContext>
        <local:Emp_Sel_Ins_Upd_Del_DomainContext></local:Emp_Sel_Ins_Upd_Del_DomainContext>
      </telerik:RadDomainDataSource.DomainContext>
  </telerik:RadDomainDataSource>

<telerik:RadDomainDataSource Name="DeptDomainDataSource"
                  QueryName="GetTblDepts"
                  AutoLoad="True"
                  Height="0" Width="0"
                  >
      <telerik:RadDomainDataSource.DomainContext>
        <local:Emp_Sel_Ins_Upd_Del_DomainContext></local:Emp_Sel_Ins_Upd_Del_DomainContext>
      </telerik:RadDomainDataSource.DomainContext>
</telerik:RadDomainDataSource>

Grid View part:

<telerik:RadGridView Name="customerGridView" Grid.Row="1" Grid.Column="1" Width="800"
                            ItemsSource="{Binding DataView, ElementName=employeesDomainDataSource}"
                            IsBusy="{Binding IsBusy, ElementName=employeesDomainDataSource}"
                            IsFilteringAllowed="False"
                            AutoGenerateColumns="False"
                            EnableColumnVirtualization="True" EnableRowVirtualization="True"
                            AutoExpandGroups="True" CellEditEnded="customerGridView_CellEditEnded" RowLoaded="customerGridView_RowLoaded">
            <telerik:RadGridView.Columns>
                <PMControls:PMGridViewDataColumn DataMemberBinding="{Binding Id}" Width="100"></PMControls:PMGridViewDataColumn>
                <PMControls:PMGridViewDataColumn DataMemberBinding="{Binding Name}" Width="150"></PMControls:PMGridViewDataColumn>
                <PMControls:PMGridViewDataColumn DataMemberBinding="{Binding Designation}" Width="100"></PMControls:PMGridViewDataColumn>
                <PMControls:PMGridViewDataColumn DataMemberBinding="{Binding Salary}" Width="100"></PMControls:PMGridViewDataColumn>
                <PMControls:PMGridViewDataColumn DataMemberBinding="{Binding DateOfJoin}" Width="170" DataFormatString="{}{0:d}"></PMControls:PMGridViewDataColumn>
           
                <telerik:GridViewComboBoxColumn x:Name="DeptCombo" Header="Department" Width="150"  
                        DataMemberBinding="{Binding DeptId}"
                        SelectedValueMemberPath="DeptId"
                        DisplayMemberPath="DeptName"
                        IsSortable="False"
                        ItemsSource="{Binding DataView, ElementName=DeptDomainDataSource}">
                </telerik:GridViewComboBoxColumn>
            </telerik:RadGridView.Columns>
        </telerik:RadGridView>

In this the problem is, the Combo Box is not loading when the grid is initially loaded. The Combo Box is loading only when we click on the particular column which has the combo boxes.

Please help.

Hello SivaPrasad Bevara,

May you take a look at this article for a reference on the same topic ? Furthermore, you may test the sample project attached in this forum thread for the implementation of the GridViewComboBoxColumn in a similar scenario like yours.
