Hidden Column not possible | Infragistics Forums

Hello Martin,

I have built small sample based on provided details by you. I am not able to replicate the described issue. Could you have a look at it please? You can download it from the current post.

In the sample I am using your code as much as possible.

aspx markup :

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
        <ContentTemplate>

            <ig:WebDataGrid ID="WebDataGrid1"

runat="server"

Height="350px"

Width="98%"

               AutoGenerateColumns="false">
                <Behaviors>
                    <ig:Selection RowSelectType="Multiple"

CellClickAction="Row" Enabled="true" />
<ig:RowSelectors RowNumbering="true"

                    Enabled="true" />
                </Behaviors>
            </ig:WebDataGrid>

        </ContentTemplate>
    </asp:UpdatePanel>

Code file:

  if (!Page.IsPostBack)
        {

            //Add behavior
            this.WebDataGrid1.Behaviors.CreateBehavior<Paging>();
            //Handle PageIndexChanged event
            this.WebDataGrid1.Behaviors.Paging.PagingClientEvents           .PageIndexChanged = "WebDataGrid1_PageIndexChanged";

            BoundDataField Datacolumn1 = new BoundDataField();
            Datacolumn1.DataFieldName = "id";
            Datacolumn1.Key = "id";
            Datacolumn1.Header.Text = "id";
            Datacolumn1.Hidden = true;
            WebDataGrid1.Columns.Add(Datacolumn1);

            Datacolumn1 = new BoundDataField();
            Datacolumn1.DataFieldName = "Item";
            Datacolumn1.Key = "Item";
            Datacolumn1.Header.Text = "Item";
            Datacolumn1.Hidden = false;
            WebDataGrid1.Columns.Add(Datacolumn1);

            Datacolumn1 = new BoundDataField();
            Datacolumn1.DataFieldName = "Data";
            Datacolumn1.Key = "Data";
            Datacolumn1.Header.Text = "Data";
            Datacolumn1.Hidden = false;
            WebDataGrid1.Columns.Add(Datacolumn1);
        }
        WebDataGrid1.DataSource = this.MakeTable();

        WebDataGrid1.DataBind();

        this.WebDataGrid1.Behaviors.Paging.PagerTemplate = new CustomPagerTemplate();

Datacolumn1.Hidden = true;
            WebDataGrid1.Columns.Add(Datacolumn1);

            Datacolumn1 = new BoundDataField();
            Datacolumn1.DataFieldName = "Item";
            Datacolumn1.Key = "Item";
            Datacolumn1.Header.Text = "Item";
            Datacolumn1.Hidden = false;
            WebDataGrid1.Columns.Add(Datacolumn1);

            Datacolumn1 = new BoundDataField();
            Datacolumn1.DataFieldName = "Data";
            Datacolumn1.Key = "Data";
            Datacolumn1.Header.Text = "Data";
            Datacolumn1.Hidden = false;
            WebDataGrid1.Columns.Add(Datacolumn1);
        }
        WebDataGrid1.DataSource = this.MakeTable();

        WebDataGrid1.DataBind();

        this.WebDataGrid1.Behaviors.Paging.PagerTemplate = new CustomPagerTemplate();

As you can see I hide the first column as you suggested.

Let me know what I am missing in this sample to get the error.

WebDataGrid1.Columns.Add(Datacolumn1)

WebDataGrid1.DataSource = MyRS

WebDataGrid1.DataBind()

if i do that , i've got the following error

Die Steuerelementeauflistung kann nicht geändert werden, da das Steuerelement Codeblöcke enthält (z.B. <% ... %>).

hi, (currently use version 10 vol 2) i want a column (auto id ) hide from showing in the grid .i do the following Dim Datacolumn1 As New BoundDataField Datacolumn1.DataFieldName = "L_ID" Datacolumn1.Key = "L_ID" Datacolumn1.Header.Text = "L_ID" Datacolumn1.Hidden = True

WebDataGrid1.Columns.Add(Datacolumn1)

WebDataGrid1.DataSource = MyRS

WebDataGrid1.DataBind()if i do that , i've got the following error
