Question

What i’m trying to do is basically create one way to verify that all textboxes are full. So if i Have 11 textboxes on one page I can basically run this QC check and verify each textbox ha some information.

this is what I’m trying to do but it’s not working out.

private void VerifyTextBoxes()
{
    Control[] AllTextBoxes = FindControl("TextBox");
    foreach(Control c in AllTextBoxes)
    {
        //verify work here
    }
}

The problem is two fold, I know that FindControl is not converted into an [], but i’m not sure how to do that. Also, the FindControl is looking for an ID name, is there a way to find it by type? For example all TextBoxes? Or all ComboBoxes?

Here is my aspx

<asp:Content ID="Content1" ContentPlaceHolderID="AdministrationContent" runat="Server">
<ul>
    <li>
        <asp:Label ID="DealerShipID" runat="server" Text="Dealership ID"></asp:Label>
    </li>
    <li>
        <telerik:RadTextBox ID="InputDealershipID" runat="server" Width="250px">
        </telerik:RadTextBox>
    </li>
</ul>

You could loop through all controls and pull out only the TextBoxes:

protected void Page_Load(object sender, EventArgs e)
{
    List<RadTextBox> allTextBoxes = new List<RadTextBox>();
    FindTextBoxes(this, allTextBoxes);

    foreach (RadTextBox tb in allTextBoxes)
    {
        // Do something here.
    }
}

private void FindTextBoxes(Control parent, List<RadTextBox> allTextBoxes)
{
    foreach (Control c in parent.Controls)
    {
        RadTextBox tb = c as RadTextBox;
        if (tb != null)
        {
            allTextBoxes.Add(tb);
        }

        FindTextBoxes(c, allTextBoxes);
    }
}
