Hello there,

I have a webdatagrid, in which a webdropdown is activated.

I load the webdropdown like this:

        private void FillIndRoleAttribDropDown(DropDown control, TmpIndRoleAttribute tmpAttr)
        {
            List<INDROLE_ATTRIBUTE_TYPE> types = GetRoleAttributeTypes();
            control.DataSource = types;
            control.ValueField = "IR_ATTR_TYPE_CDE";
            control.TextField = "DESCR";
 
            control.DataBind();

            control.Enabled = (tmpAttr.IR_ATTR_ID < 0);

            if (!string.IsNullOrEmpty(tmpAttr.IR_ATTR_TYPE_CDE))
                control.SelectedItemIndex =
                    types.Select(r => r.IR_ATTR_TYPE_CDE).ToList().IndexOf(tmpAttr.IR_ATTR_TYPE_CDE);
            else
                control.Items.Insert(0, new DropDownItem(PrfUIConstants.AdditionalItmes.NotSelected, string.Empty));
        }

I shoot this code at the initialize-row event of the grid.

The problem is, I get a strange flickering, when I open this list of this dropdown. I found in the internet the solution, to set the EnableDropDownAsChild Property to false and set the z-index as high as possible.

This might fix the flickering problem, but now I cant open the dropdown, when a value is selected. I tried to set the EnableAutoCompleteFirstMatch Property to false, but this didnt work.

Is there a solution for this?
