Webdatagrid template data field
posted

I have a field I am creating a web image button (template data field), within the grid, which allows them to sign up for a class.  It will allow them to proceed to the next page if clicked.  I would like to be able to show a label instead of the button if the class is full.  Is this possible?  I would be getting the "toggle" item from the database (from within the datasource populating the grid).  Thanks in advance for your help.

    Hello bpabmeyer,

    you can handle InitializeRow event and populate templated column based on some condition. Use Item Template 


            <ig:WebDataGrid ID="WebDataGrid1" runat="server" Height="350px" Width="400px" 
                AutoGenerateColumns="False" DataSourceID="SqlDataSource1" 
                oninitializerow="WebDataGrid1_InitializeRow">
                <Columns>
                    <ig:BoundDataField DataFieldName="ProductID" Key="ProductID">
                        <Header Text="ProductID" />
                    </ig:BoundDataField>
                    <ig:BoundDataField DataFieldName="ProductName" Key="ProductName">
                        <Header Text="ProductName" />
                    </ig:BoundDataField>
                    <ig:TemplateDataField Key="TemplateField_0">
                        <Header Text="TemplateField_0" />
                    </ig:TemplateDataField>
                </Columns>
            </ig:WebDataGrid>



    

       protected void WebDataGrid1_InitializeRow(object sender, Infragistics.Web.UI.GridControls.RowEventArgs e)
    {
        //check some condition
        if (e.Row.Items[1].Text == "Chef Anton's Cajun Seasoning")
        {
            e.Row.Items[2].Template = new CustomItemTemplate();
        }
        else
        {
            e.Row.Items[2].Text = "No avaiable classes";
        }
    }

    private class CustomItemTemplate : ITemplate
    {
        #region ITemplate Members

        public void InstantiateIn(Control container)
        {

            LinkButton edit = new LinkButton();
            edit.CssClass = "LinkButton";
            edit.Text = "Edit";
            edit.OnClientClick = "return editRow()";

            LinkButton delete = new LinkButton();
            delete.CssClass = "LinkButton";
            delete.Text = "Delete";
            delete.OnClientClick = "return deleteRow()";

            container.Controls.Add(edit);
            container.Controls.Add(delete);
        }

        #endregion
    }



    I hope this helps
