Getting unhandled exception when DataTemplate is created dynamically using Silverlight 3.0
- by Bhaskar
Requirement is to create a reusable multi-select combobox custom control. To accomplish this, I am creating the DataTemplate dynamically through code and set the combobox ItemTemplate. I am able to load the datatemplate dynamically and set the ItemTemplate, but getting unhandled exception (code: 7054) when combobox is selected.
Here is the code
Class MultiSelCombBox: ComboBox
{
public override void OnApplyTemplate()
{
base.OnApplyTemplate();
CreateTemplate();
}
void CreateTemplate()
{
DataTemplate dt = null;
if (CreateItemTemplate)
{
if (string.IsNullOrEmpty(CheckBoxBind))
{
dt = XamlReader.Load(@"<DataTemplate xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation' xmlns:x='http://schemas.microsoft.com/winfx/2006/xaml' x:Name=""DropDownTemplate""><Grid xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation' xmlns:x='http://schemas.microsoft.com/winfx/2006/xaml' x:Name=""CheckboxGrid""><TextBox xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation' xmlns:x='http://schemas.microsoft.com/winfx/2006/xaml' x:Name=""test"" xml:space=""preserve"" Text='{Binding " + TextContent + "}'/></Grid></DataTemplate>") as DataTemplate;
this.ItemTemplate = dt;
}
}
}
//Other code goes here }}
what am i doing wrong? suggestion?
