Grid with dropdown for insert and edit

[Brendan Vogt]

Hi,

I have a column in my grid, here is the code:

<radG:GridBoundColumn
   DataField="Title.Description"
   HeaderText="Title"
   UniqueName="Title.Description">
</radG:GridBoundColumn>

The problem that I am having is the following..

1. When the Insert new record link is clicked, this title field must become a dropdownlist with all the titles populated.
2. When the Edit link is clicked, this title field must become a dropdownlist with all the titles populated, and the current title must be selected in the drop down.

Please can some one help me, I have been through the forums and can't find something suitable.

Thanks
Brendan

Hello Brendan,

Please take a look at the following online demo:
RadGrid Automatic operations

The above illustrated functionality is achieved using regular GridDropDownColumn.

Hi,

The example does it like this:

<telerik:GridDropDownColumn
   DataField="CategoryID"
   DataSourceID="SqlDataSource1"
   HeaderText="Category"
   ListTextField="CategoryName"
   ListValueField="CategoryID"
   UniqueName="CAtegoryID">
</telerik:GridDropDownColumn>

I previously had it my title text displayed like this in the grid, but then it became a textbox in the edit and insert:

<radG:GridBoundColumn
   DataField="Title.Description"
   HeaderText="Title"
   UniqueName="Title.Description">
</radG:GridBoundColumn>

How do I do the above the same for the GridDropDownColumn column?

Please help.

Brendan

Hello Brendan,

The code you provided is insufficient to supply an appropriate answer as there is no information about your datasource.

Quote from the documentation:

<rad:GridDropDownColumn
UniqueName="LevelID"
ListDataMember="Level"
ListTextField="Description"
ListValueField="LevelID"
HeaderText="LevelID"
DataField="LevelID" />

"As you can see, a requirement for the proper functioning of GridDropDownColumn is that all column values referenced by the DataField attribute match the column values referenced by the ListValueField attribute. If there are values in the LevelID column of the LevelID table which do not have corresponding equal values in the LevelID column of the Level table, then the grid will display the default first value from the Description column as it will not "know" what is the correct field."
