Error when trying to filter on a Dictonary<int, string>

[Mike]

Hi there,

I'm using a custom GridTemplateColumn to do some filtering. The filter combo-box is bound to a Dictionary<int, string> and renders with no problems; it's bound with:

            rcBox.DataTextField = "value";
            rcBox.DataValueField = "key";

When I try to select an item from the list however, I get an error message "Expression expected" with the following code:

        private void rcBox_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)
        {
            ((GridFilteringItem)(((RadComboBox)sender).Parent.Parent)).FireCommandEvent("Filter", new Pair());
        }

The code was previously:

        private void rcBox_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)
        {
            ((GridFilteringItem)(((RadComboBox)sender).Parent.Parent)).FireCommandEvent("Filter", new Pair("EqualTo", this.UniqueName));
        }

but that also gives "Expression Expected" with a UniqueName value of "key".

Any thoughts?

Thank you,

Mike K.

Hi Mike,

I advise you to try setting the EnableLinqExpressions property of the grid to false. Let us know if the issue persists afterwards.

I'm no longer using the GridTemplateColumn, so it's a moot point now, but thank you for your help.
