ComboBox Width

[Jonathan]

Hi,

Is there are simple way with RadComboBox to set the width of the combo to the pixel size of the width of the longest item currently in the dropdown?  This would apply to both the combobox itself and the dropdown.

Thanks,

[Simon]

Hello Jonathan,

Currently RadComboBox does not support this feature, but it has already been logged in our To-Do list.

I hope that this is not a major show-stopper for you.

Does anyone know whether this feature is now supported?

Hi Chris Studman,

This feature is not supported by RadComboBox, yet.

We have encountered certain difficulties in its implementation and are still researching to find the best approach. A time frame on when it will be introduced is unavailable at the moment.

Bump: is this supported in build 1001?

Hi Matthew Howell,

Unfortunately this feature is not yet part of the functionality of RadComboBox. On the other hand, if we receive enough customer requests for the feature perhaps we can include it in our TODO list.

However you could always use an approach like the shown below to achieve the desired effect:

[C#]

int maxWidth = 0;

foreach (RadComboBoxItem item in RadComboBox1.Items)
{
    int itemLength = item.Text.Length;

    if (itemLength > maxWidth)
    {
        maxWidth = itemLength;
    }
}

RadComboBox1.DropDownWidth = maxWidth * 7;

[VB.NET]

Dim maxWidth As Integer = 0

For Each item As RadComboBoxItem In RadComboBox1.Items
    Dim itemLength As Integer = item.Text.Length

    If itemLength > maxWidth Then
        maxWidth = itemLength
    End If
Next

RadComboBox1.DropDownWidth = maxWidth * 7

I hope this helps.

Best wishes,

I support this feature as well, I hope it can be added to the TODO list. Ideally it would support boundary detection too, just like the combobox height.

I use this method, but it adds the scrollbars to the dropdown. When I just hardcoded the widths, the scrollbars are added. Is there a way to remove the scrollbars (rcbScroll)?

Same problem with both horizontal and vertical scrollbars added to combobox when hardcoding the size of the list in IE. In Firefox this doesn't give this problem.
