In most of the web applications you may need to add a reset button to clear the values of a form which is having dropdown and textboxes, in this situation most of the developers are doing this by adding code like TextBox1.Text =""; and DropDown1.SelectedValue="0", there is a simple solution to do this.
See below code:
public static void ResetControls(ControlCollection pagecontrols, bool txtbox, bool dropdownlist, bool label)
{
foreach (Control cntrl in pagecontrols)
{
foreach (Control mycontrols in cntrl.Controls)
{
if (txtbox)
{
if (mycontrols is TextBox)
{
(mycontrols as TextBox).Text = string.Empty;
}
}
if (dropdownlist)
{
if (mycontrols is DropDownList)
{
(mycontrols as DropDownList).SelectedIndex = 0;
}
}
if (label)
{
if (mycontrols is Label)
{
(mycontrols as Label).Text = string.Empty;
}
}
}
}
}
You can call the function using following syntax:
FormControl.ResetControls(this.Controls, true, true, false);
Above statement resets all controls except label in the current form
