Nested GridView Control returns "Object variable or With block variable not set" when outer GridView

Posted By:      Posted Date: October 21, 2010    Points: 0   Category :ASP.Net

Nested GridView Control returns "Object variable or With block variable not set" when outer GridView returns rows.

The Nested GridView Control works as long as the outer GridView returns rows, the following code works:


Protected Sub GridViewReport_RowCreated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridViewReport.RowCreated

          If e.Row.RowType = DataControlRowType.DataRow Then

                 Dim myStatus_ID As SqlDataSource = CType(e.Row.FindControl("sqlDeviceStatusAssign"), SqlDataSource)
                 If Not e.Row.DataItem("Status_ID") Is Nothing Then
                                  myStatus_ID.SelectParameters(0).DefaultValue = e.Row.DataItem("Status_ID")
                 End If

       End If

Using TemplateFields in the GridView Control

The GridView is composed of a set of fields that indicate what properties from the DataSource are to be included in the rendered output along with how the data will be displayed. The simplest field type is the BoundField, which displays a data value as text. Other field types display the data using alternate HTML elements. The CheckBoxField, for example, renders as a checkbox whose checked state depends on the value of a specified data field; the ImageField renders an image whose image source is based upon a specified data field. Hyperlinks and buttons whose state depends on an underlying data field value can be rendered using the HyperLinkField and ButtonField field types.

Reuse a gridview within calendar control


Hello, I have a calendar control that will have events displayed within each cell.

I want to use a pre formatted gridview and simply bind the gridview with a dataset dynamically and display it within the cell of the specified day.

Is there a way to do that or do I have to dynamically build a gridview for every day that there is an event? 

So here is the template gridview and datasource:

 <asp:SqlDataSource ID="sqlcalitemtemp" runat="server" 
        ConnectionString="<%$ ConnectionStrings:NNTrainingdbconnection %>" 
        SelectCommand="SELECT NN_Fire_Events.Start_Time, NN_Fire_Events.End_Time, tblNN_Fire_Cli

Editable multiple nested gridview


Greetings everyone,

I've got this page where I display a 3 level nested gridview. First gridview displays data, 2nd one displays data based on the 1st one's row and 3rd one displays data based on the 2nd gridview. All of this works perfectly, including the edit mode for the 3rd gridview. 

The issue comes when I make each gridview collapsible, again, it works fine but when I click on "Edit" on the 3rd gridview all the grids collapse, I can then re-open them and the "edit mode" is still present and I can still save my updated data. But that collapsing thing is quite annoying.

I based a lot of my code from this page: http://www.codeproject.com/KB/webforms/EditNestedGridView.aspx

And I understand how I can fix my issue on a 2 level nested gridview, by simply adding the C# code:

protected void GridView2_RowEditing(object sender, GridViewEditEventArgs e)
            GridView gvTemp = (GridView)sender;
            gvUniqueID = gvTemp.UniqueID;
            gvEditIndex = e.NewEditIndex;

This makes allows me to save the index and prevent it from collapsing when I'm editing. Unfortunately, because I'm actually editing the 3rd gridview, if I code:
