maxlength property on RadFilterNumericFieldEditor and RadFilterTextFieldEditor

[alpesh]

Hi,

I dont see the maxlength property on RadFilterNumericFieldEditor and RadFilterTextFieldEditor.
Is there a way we can set the maxlength on these items?

Thanks

Hi Alpesh,

I have assembled a sample project showing the desired functionality implemented. The idea is to loop through all RadNumericTextBox and TextBox controls in the RadFilter and set their MaxLenght property as shown below.

protected override void OnPreRender(EventArgs e)
{
    base.OnPreRender(e);
    List<Control> controls = new List<Control>();

    FindControlRecursive(this.RadFilter1, controls, typeof(TextBox));
    FindControlRecursive(this.RadFilter1, controls, typeof(RadNumericTextBox));
    foreach (Control control in controls)
    {
        TextBox textBox = control as TextBox;
        RadNumericTextBox numeric = control as RadNumericTextBox;
        if (textBox != null)
        {
            textBox.MaxLength = 2;
        }
        else if (numeric != null)
        {
            numeric.MaxLength = 2;
        }
    }
}

public static void FindControlRecursive(Control container, List<Control> controls, Type type)
{
    if (container.GetType() == type)
    {
        controls.Add(container);
    }

    if (container.Controls.Count == 0)
    {
        return;
    }

    foreach (Control ctrl in container.Controls)
    {
        FindControlRecursive(ctrl, controls, type);
    }
    return;
}

All the best,
