I have a radgrid that is a master detail. In the detail table, I have a column with a radcombobox. The datasource returns a query that has a value and display column and the value coming from the db is type numeric. Thus far in .net, when referencing these values I reference them as decimal. For this combobox, I set the type to be System.decimal but it is always showing the empty list item text and is uneditable. Below is the snippet from the help file and my combobox.
Ensure that the fields specified through the DataField/ListValueField properties are of the same data type and the entries have a precise match, otherwise you will get merely the first item from the list displayed in non-editable mode. This can also happen if you have not configured properly the GridDropDownColumn, e.g. the relations between the fields specified through the DataField/ListValueField properties.
<telerik:GridDropDownColumn DataSourceID="dsGetEmailAddressType"
DataField="emailAddressTypeSeq"
ListTextField="typeAcronym" ListValueField="emailAddressTypeSeq"
CurrentFilterFunction="NoFilter"
FilterListOptions="VaryByDataType"
ForceExtractValue="None" HeaderText="Type"
UniqueName="emailAddressTypeSeq"
DataType="System.Decimal" DropDownControlType="RadComboBox"
EmptyListItemText="Please Select" EmptyListItemValue="" EnableEmptyListItem="true">
</telerik:GridDropDownColumn>
