Adding background to Combobox

[Erik]

Hi,

I try to add background to combo box by setting the background image.
But I didnt get what i want. The background was showing. How to set the background image?

Secondly, is it possible to add item image to combo box bounded to database?


thanks

Hi eriksurya,

Although the BackGroundImage property is accessible, it is unfortunately inherited from System.Windows.Forms.Control and does not apply to RadComboBox.

As to the your second question, if I understand correctly your goal is to add an image to every item that is shown in the drop-down window. Such case is demonstrated in the "Music Collection" example of the RadComboBox. In this example an image list control is used and the corresponding image index is retrieved from the data source. Then on the RadComboBox.ItemDataBound event the images are loaded in the items:
 

void cmbArtist_ItemDataBound(object sender, ItemDataBoundeventArgs e)
{
    RadComboBoxItem item = e.DataBoundItem as RadComboBoxItem;
    item.TextImageRelation = TextImageRelation.ImageBeforeText;
    PropertyDescriptor desc = TypeDescriptor.GetProperties(e.DataItem).Find("ImageIndex", false);
    item.ImageIndex = (int)desc.GetValue(e.DataItem);
}

I hope this helps!

Thanks

Hello eriksurya,

Only the background color of the textbox part of the RadComboBox can be changed. This can be done in the theme using the Visual Style Builder, where you can set the RadTextBoxItem.BackColor property to the desired color.
