I have a select statement in code infront as following:

<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:VSGIHURConnectionString %>"
   SelectCommand="SELECT distinct size,UniformID FROM [uniforminfo] where UniformName='+lbl_uniformid+' and status= 'a' ORDER BY UniformID">

the UniformName is based on the selection of lbl_uniformid in the grid. The question is how can i rewrite the above sql statement "where UniformName='+lbl_uniformid+'" based on the user selected uniformid (means when user choose a uniformid in the grid then the select statement will select a correct size based on the user chosen uniformid)?

Here is the code of UniformName in the grid

<asp:TemplateField HeaderText="Type Of Uniform" Visible="true" ItemStyle-Width="200" >
            <asp:Label ID="lbl_uniformid" runat="server" Text='<%#Eval("uniformgroupname") %>'

         <asp:TextBox ID="ddl_uniformgroupname" runat="server" AutoPostBack="true" runat="server"
            BackColor="White" CompletionListCssClass="completeListStyle"
            Text='<%# Eval("uniformgroupname") %>' ontextchanged="txt_ddl_uniformgroupname"
            style="font-family: 'Century Gothic';" Visible="true"
        <asp:AutoCompleteExtender ID="ddl_uniformgroupname_AutoCompleteExtender" runat="server" CompletionInterval="100"
    CompletionListCssClass="completeListStyle" DelimiterCharacters="" Enabled="True"
    MinimumPrefixLength="0" ServiceMethod="GetCompletion_ddl_uniformgroupname" ServicePath=""

Appreciate to anyone who want to assist my problem.

Thanks a lot & H@ppy 2013.

The way you are doing this, is totally wrong. You need to use Parameters in SqlDataSource Control. It seems you need to do a lots of practice on it. Just visit the below links:
