In this simple example (found here in the forum) for setting the filtering in code behind I get a "Expression Expected" error.

I have already set the EnableLinqExpression="false" in the grid.

public enum MyEnum

{

Value1,

Value2,

Value3,

Value4,

Value5

}

public partial class Default : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

}

protected void RadButton1_Click(object sender, EventArgs e)

{

if (RadGrid1.MasterTableView.FilterExpression == "")

{

RadGrid1.MasterTableView.FilterExpression = "([Value] = '" + MyEnum.Value1 + "')";

}

else

{

RadGrid1.MasterTableView.FilterExpression = "";

}

RadGrid1.Rebind();

}

protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)

{

DataTable table = new DataTable();

table.Columns.Add("Key");

table.Columns.Add("Value");

for (int i = 1; i < 6; i++)

{

table.Rows.Add("Key" + i.ToString(), "Value" + i.ToString());

}

RadGrid1.DataSource = table;

}
