I have a table ‘TYPE’ in this table i have 2 columns as ‘SKEY’

0

I have a table ‘TYPE’ in this table i have 2 columns as ‘SKEY’ AND ‘CASECODE’.

‘SKEY’ contains text value and ‘CASECODE’ contains the corresponding numeric value.

I have bound the values in the column ‘SKEY’ to a DropdownList control in ASP.net 3.5 C#, What i want is on selection of one item in the DropdownList the corresponding value in the column ‘CASECODE’ should be displayed.

I have created a datasource for a dropdown list and i want to have DataTextField which is visible to the user to be a value from column SKEY and dropdownlistDataValueField to be a value from column ‘casecode’ but when i try to do

<asp:DropDownList ID="DropDownList3" runat="server" 
            DataSourceID="SqlDataSource1" DataTextField="skey" DataValueField="casecode" 
            AppendDataBoundItems="True">
            <asp:ListItem Selected="True" Value="S">Select</asp:ListItem>
        </asp:DropDownList>

DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'casecode'.

The select command of your data source does not include a field named casecode:

<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
        ConnectionString="<%$ ConnectionStrings:ConnectionString2 %>" 
        ProviderName="<%$ ConnectionStrings:ConnectionString2.ProviderName %>" 
        SelectCommand="SELECT testcase.casetype.skey FROM testcase.casetype">
</asp:SqlDataSource>

Probably you want to edit SelectCommand to something like this (depending on how your database looks like):

SelectCommand="SELECT testcase.casetype, testcase.casetype.skey FROM testcase.casetype"
