RibbonBar DropDownList enable and set selected

[Bastian]

Hi,

 

I'm having problems with the RibbonBarDropDown. I'm having two RibbonBarDropDowns and as soon as in one is a specifc item selected, the other gets enabled.

I'm using RadAjaxManger and the "OnClientDropDownSelectedIndexChanged" event to do the ajax request.

In my code behind i'm doing the following:

List<string>boxValues = ViewModel.GetBoxValues();

SecondBox.Items.Clear();
SecondBox.Items.AddRange(boxValues.Select(x => new RibbonBarListItem() {Text = x}));
if(boxValues.Count > 0)
{
    SecondBox.Enabled = true;
    SecondBox.SelectedIndex = 0;
}
else
{
    SecondBox.Enabled = false;
}

 

Everything is working fine except setting the selectedIndex. The selectedIndex is only set to 0 if the RibbonBarDropDown was enabled before.

Any suggestions what i'm doing wrong?

Hello Bastian,

If I understand you well you are not able to set SecondBox.SelectedIndex = 0; after SecondBox.Enabled = false;. We have tested the scenario locally and even disabled, the DropDown allows to change its selected index from the code-behind. Please, let us know if we are missing something in this case.

You could also post here the declaration of your control in the markup and the OnClientDropDownSelectedIndexChanged handler that you have implemented. This way, we will be able to help you more accurately.

Hello Veselin,

 

I found a solution for my problem. I had a databinding for the "SecondBox.SelectedIndex", setting the bound property to 0 and the setting the SecondBox enabled worked fine.

 

Anyways, thanks for your fast response!
