Identify textbox whose text matches combobox in vb.net

Hi all.

I'm working on a vb.net form in Visual Studio 2012 that has 5 textboxes (txtbox1, txtbox2, etc.) and a combobox (mycombobox).

The combobox list shows the 5 values in each of the textboxes described above. After the end user selects an item from the combobox I want to display in a message box which textbox has the exact value. So the message box would display "txtbox1" if the text inside of it matched what was selected in the combobox.

Any ideas?

Thank you in advance.

How are you populating the ComboBox? If you post that code it'll help in determining the correct textbox.

Private Sub cmbSetMin_Enter(sender As System.Object, e As System.EventArgs) Handles cmbSetMin.Enter

        cmbSetMin.Items.Clear()

        If Not (String.IsNullOrWhiteSpace(txtQty2.Text)) Then cmbSetMin.Items.Add(txtQty2.Text)
        If Not (String.IsNullOrWhiteSpace(txtQty3.Text)) Then cmbSetMin.Items.Add(txtQty3.Text)
        If Not (String.IsNullOrWhiteSpace(txtQty5.Text)) Then cmbSetMin.Items.Add(txtQty5.Text)
        If Not (String.IsNullOrWhiteSpace(txtQty7.Text)) Then cmbSetMin.Items.Add(txtQty7.Text)
        If Not (String.IsNullOrWhiteSpace(txtQty9.Text)) Then cmbSetMin.Items.Add(txtQty9.Text)

        cmbSetMin.SelectedIndex = -1

    End Sub

		For Each ctl As Control In Me.Controls
			If TypeOf ctl Is TextBox AndAlso ctl.Text = ComboBox1.Text Then
				MessageBox.Show(ctl.Name)
			End If
		Next

Open in new window


This will loop through all the TextBox controls on the form. If you want to make sure that you check only for specific controls, add something in their Tag property (X in the following example) and go like this:

 
		For Each ctl As Control In Me.Controls
			If CStr(ctl.Tag)="X" AndAlso ctl.Text = ComboBox1.Text Then
				MessageBox.Show(ctl.Name)
			End If
		Next
