How add GridDropDownColumn

[ang]

Somebody may explain me how add a

GridDropDownColumn in the designer?

In the property builder I don't see any column type diffrente from:

boundColumn, buttonColumn, hyperLinkColumn and templateColumn.

Thanks, angdrak

In the columns editor of the masterTableview, the down arrow in the Add button, is not visible and clicking it, allways get the error
not possible to create an instance of Telerik.Web.UI.gridcolumn because is an abstract class.

Hi, I downloaded and reinstalled the new rad prometheus, but now in visual studio 2005 designer in components places get a box with the "error during control creation tag server telerik.radmenu unknown".
I already tried to delete and recreate the reference to the dll, but without any effect.

Wath to do?

Thanks, Angdrak

Hello Ang,

Could you please make sure that the Telerik.Web.Design.dll file (in the bin or GAC) is of the same version as the Telerik.Web.UI.dll file?


Best wishes,

Hi, I have found wath the problem was, for some obscure reason VS2005 does not ever update correcty the web.config file when you add a reference. So putting that manually solve the problrm.

Now where may I find some sample on the griddropdown column settings.

Thanks,  Andrak

Ok, thanks now the column works and update the DB column too, but allways show the first item of the list. How get the selected item be syncronized with value of DB?

ang, if you set up the column as told in the help article it should display the correct selection from the DB. You will get only the first item in the list if you did not do that or the relations between the key fields for the grid and the dropdown column are not valid.

Maybe I am wronging something, but cannot figure wath.
I send you a part of my aspx, may you kindly help me?

is a simple lookup from the CUST table using CUST_COUNTRY on the COUNTRY table, that has COUNTRY_ID as Primary key and COUNTRY_DESCR as description.

                <telerik:GridDropDownColumn CurrentFilterFunction="NoFilter" DataField="CUST_COUNTRY"
                    DataSourceID="SDSCOUNTRY" FilterListOptions="VaryByDataType" ForceExtractValue="None"
                    ListTextField="COUNTRY_DESCR" ListValueField="COUNTRY_ID" UniqueName="column1">
                </telerik:GridDropDownColumn>

.............>

   <asp:SqlDataSource ID="SDSCust" runat="server" ConnectionString="<%$ ConnectionStrings:benConnectionString %>"
        SelectCommand='SELECT * FROM "TR_CUST"'
   </asp:SqlDataSource>

   <asp:SqlDataSource ID="SDSCountry" runat="server" ConnectionString="<%$ ConnectionStrings:benConnectionString %>"
    ProviderName="<%$ ConnectionStrings:benConnectionString.ProviderName %>"
    SelectCommand='SELECT "COUNTRY_ID", "COUNTRY_DESCR" FROM "SHARED_COUNTRY" ORDER BY "COUNTRY_DESCR"'></asp:SqlDataSource>

Thank you for help,  Angdrak

AngDrak, do you have primary -> foreign key relation between a field in the grid's source table and the COUNTRY_ID field from the SHARED_COUNTRY table? Read once again the topic from the docs named Customize/Configure GridDropDownColumn and have in mind these relation when setting up the column.

Prangadj

[ang]

Yes, it is so. And I setted the dropDownColumn properties in the  following way:
DataSourceID="SDSCOUNTRY" (SQLDataSource of SharedCountry Table)
DataField="CUST_COUNTRY" (Foreign key from Cust Table to     Shared_Country)
ListValueField="COUNTRY_ID"  (Primary key column in shared_country table)
ListTextField="COUNTRY_DESCR" (Country description in shared_country table, that I want list in dropDownColumn)?

There is somthing wrong in the above settings?

Thanks, Angdrak

[Prangadj]

Check that CUST_COUNTRY and COUNTRY_ID are of the same data type and they are equal (no empty spaces for values in them). The other part looks fine to me.
