[Solved] what all characters are reserved in radgrid filter

[Manish]

Hi Team,

I am using the radgrid with filter and I am getting error on "|" character and "\" character  is automatically removed/ignored by control. So please let me know list of character that are not being supported as input in filter textbox.

Thanks,
Manish

Hi Manish,

The GridFilterFunction.IllegalStrings array contains all strings that if entered will cancel the filtering.

• " LIKE ", " AND ", " OR ", "\"", ">", "<", "<>", " NULL ", " IS "

You could modify the collection on Page_Init event and in order to change the illegal strings. Note that this is developer responsibility which could cause potential security problems.

protected override void OnInit(EventArgs e)
{
    base.OnInit(e);
    GridFilterFunction.IllegalStrings = new string[] { " LIKE ", " AND ", " OR ", ">", "<", "<>", " NULL ", " IS " };
}
