FilterTemplate + error

[Tomasz]

 

 

Hello I want to filter column in my grid with filtertempalte column including RadComboBox
the code look like this(i have already read the blogs and have seen the demos about filter template)

<telerik:GridTemplateColumn DataField="Obraz" Visible="false" Resizable="false" UniqueName="TemplateColumn"

 

 

 

AllowFiltering="true">

 

 

 

<FilterTemplate>

 

 

 

<telerik:RadComboBox ID="ComboFilterBox" runat="server" AppendDataBoundItems="true" OnSelectedIndexChanged="FilterCombo_SelectedIndexChanged" DataTextField="Obraz" DataValueField="Obraz"

 

 

 

OnLoad="Combo_NeedDataSource" AutoPostBack="true">

 

 

 

<items>

 

 

 

<telerik:RadComboBoxItem />

 

 

 

</items>

 

 

 

</telerik:RadComboBox>

 

 

 

 

</FilterTemplate>

 

 

 

<ItemTemplate>

 

 

 

<asp:Image ID="Image1" runat="server" ImageUrl="<%# bind('Obraz') %>" ForeColor="White" />

 

 

 

</ItemTemplate>

 

 

 

<HeaderStyle Width="170" />

 

 

 

<ItemStyle Width="170px" />

 

 

 

</telerik:GridTemplateColumn>

and then in Code-Behind I have placed the function

 

 

protected

 

 

void FilterCombo_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e)

 

 

{

 

 

 

 

string filterExpression;

 

 

filterExpression =

 

 

"([Obraz] = '" + e.Value + "')";

 

 

RadGrid1.MasterTableView.FilterExpression = filterExpression;

 

RadGrid1.MasterTableView.Rebind();

 

}

and then when I change the values in combobox i get the error
 Sys.WebForms.PageRequestManagerServerErrorException: Expression expected
after Rebind.
Please help.

Hello Thomasz,

Try to set EnableLinqExpressions property of RadGrid as 'false' and check whether this eliminates the exception.

Thanks,
Princy.
