Hi Elena,

Thanks for the quick response.

Please see the below sample code.

 <ig:WebDataGrid ID="gvParams" runat="server" EnableDataViewState="true" AutoGenerateColumns="false">
        <Columns>
            <ig:BoundDataField Header-Text="name" DataFieldName="name" Key="name">
            </ig:BoundDataField>
             <ig:TemplateDataField Key="datatype">
                    <ItemTemplate>
                      <ig:WebDropDown ID="ddlCustomField" DisplayMode="DropDownList" AutoPostBack="true" runat="server"
            Width="120px" onselectionchanged="ddlCustomField_SelectionChanged">
                        </ig:WebDropDown>  
                    </ItemTemplate>
                </ig:TemplateDataField>
              <ig:TemplateDataField Header-Text="Properties" CssClass="WrapTextHeader" Key="Properties">
                <ItemTemplate>
                    <ig:WebDataGrid ID="gvProperties" runat="server" ShowHeader="false" EnableDataViewState="true" AutoGenerateColumns="true">
                    </ig:WebDataGrid>
                </ItemTemplate>
              </ig:TemplateDataField>
            </Columns>
    </ig:WebDataGrid>

We have one dropdown field in main grid. We need add controls dynamically based on selection.

For example we have A and B are the values in dropdown, if we select A then we need add dropdown control to internal grid in selected row. If we select B then we need to add textbox to that row.

If we select "B as value from dropdown" for 2nd row of  main grid then that specific row(3rd column internal grid data)  need to be updated. Rest of the rows of  main grid needs to be remains same.

If you need more information, please let me know.

Hi Sravani,

 

Thank you for the snippets. I am currently working over your scenario.  I will update you on my progress tomorrow.

Hello Sravani,

 

I have been looking into your scenario and I could suggest you use the SelectionChanged event of the DropDownProvider in order to set  the data source of your nested WebDataGrid:

    void EditorControl_SelectionChanged(object sender, Infragistics.Web.UI.ListControls.DropDownSelectionChangedEventArgs e)
    {

        DataTable dt = Session["ds"] as DataTable;
       
        selectedRow = (int)e.NewSelection;
        GridRecord r = WebDataGrid1.Behaviors.Selection.SelectedRows[0];
      
        dt.Rows[r.Index]["Item"] =(int) e.NewSelection;
        WebDataGrid wdg = r.Items[2].FindControl("WebDataGrid2") as WebDataGrid;

        wdg.DataSource = MakeTable((int)e.NewSelection, (int)e.NewSelection + 3);
        wdg.DataBind();
        Session["ds"] = dt;

        WebDataGrid1.RequestFullAsyncRender();

       

For additional reference you can check the attached sample.

 

Please let me know if this helps.

Hi Elena, Thanks for providing sample code. We are trying to execute the same but we are using asp.net 3.5 version. We also updated in our code but we are unable to get behaviours. We also added behaviours in aspx page. we are getting the error in below line. GridRecord r = WebDataGrid1.Behaviors.Selection.SelectedRows[0]; In the above line we are not getting the behaviours. So, grid.behaviours.selection returing null. Please do the needful. Regards, Sravani
