Hi,
I am using a UltraWinGrid and need to set a ValueList to a column, however the Data Source does not have a regular Id, Value but Name,Value, i tried looking for DataMember, ValueMember properties but no luck. i also tried to change Key property no luck again. this is my code:
UltraGrid grid = (UltraGrid)gridDefinition.Grid;
ValueList valueList = null;
if (source != null)
{
valueList = new ValueList();
valueList.Key = source.Columns[0].ColumnName;
foreach (DataRow row in source.Rows)
valueList.ValueListItems.Add(
new ValueListItem()
DataValue = row[0],
DisplayText = row[1].ToString(),
});
}
grid.DisplayLayout.Bands[0].Columns[columnKey].ValueList = valueList;

Hi and thanks for the reply.
I have a wingrid where some columns are "ComboBox" type, i fill the data source for these columns by filling the Value List. My data source is always a DataTable, the first column Key is "ID" and the second column Key is "Name" when i work like that the description inside the column is displayed correctly. however if i use a different Key for the first column ("VALUE" instead of "ID") the description is not displayed.
my question was why? and how can i tell the value list that it's "VALUEMEMBER" is "VALUE" and not "ID"?
I just wanted to know if you were able to solve your issue based on Mike's suggestions or you still need help? Just let me know.
Thank you.
Hello Itamarbe,
We are still following this forum thread.Please feel free to let us know if you still need further assistance with it.
If you are populating a ValueList in code, then you set the DataValue and DisplayText of each ValueList item on the list when you add the item. The ValueListItems.Add method takes both. And this is shown in the very first post of this thread.
If you are using another kind of ValueList which is bound, such as UltraCombo, UltraDropDown, or BindableValueList, then any of these have both a DisplayMember and a ValueMember proprerty on them.
There is no VAlueMember, DisplayMember properties in 'ValueList', that is the reason i tought that maybe 'Key' property replace "traditional" valuemember.
