Binding Combobox SelectedValue to Textbox

Question

Hi,

I have a textbox and a combobox .I want to bind combobox the selected value to text in the textbox.

Please help.

Thanks

Answer 1

This is for a listbox, not a combobox, but it should be pretty much the same code:

private void *lstProducts*_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    *currentlabel*.Content = *lstProducts*.SelectedValue.ToString();
}

The italicized bits are the names of the control.

Hope it helps...

Answer 2

<ComboBox x:Name="MyComboBox">
  <ComboBoxItem>12</ComboBoxItem>
  <ComboBoxItem>13</ComboBoxItem>
  <ComboBoxItem>14</ComboBoxItem>
  <ComboBoxItem>15</ComboBoxItem>
</ComboBox>
<TextBox Text="{Binding Path=SelectedValue.Content, ElementName=MyComboBox}" />

Since the items in the ComboBox are of type ComboBoxItem, I used the Content property to get the real value. You should use whatever property exposed by the objects in your ComboBox (use nothing if it already is a list of strings).

@julien I have similar situation. I am having a grid with two columns one having dropdown and another having textbox. Condition is that, if I select some item from the combobox then its value will get set to its respective textbox. I tried above but , no luck..
