[Solved] - Can i Display an alternate name for the list selected value?

[The GridLock]

Hi,

I changed the combobox property to dropdownlist, and I want when select all combobox items , it will display an alternate signature of "* All *" instead "Alaska.Arizona....", can I do this?

Thanks you!

Hi GridLock,

You can achieve this requirement by changing the Text of SfComboBox in SfComboBox.TextBox.TextChanged event handler. Please refer the below code snippet.

Code Snippet

sfComboBox1.TextBox.TextChanged += TextBox_TextChanged;  

private void TextBox_TextChanged(object sender, System.EventArgs e) 

{ 

    if (sfComboBox1.AllowSelectAll == true && sfComboBox1.CheckedItems.Count == sfComboBox1.DropDownListView.View.Items.Count) 

    { 

        sfComboBox1.Text = "* All *"; 

    } 

}

Thanks durai,

But if I want to get name the selected columns then I will probably have to loop them again. I mean they will be obscured, but I can still access them by calling combobox.text
