hello,
I am using IN clause in where condition in SQLdatasource which is assigned to gridview. I am providing values for IN clause using HiddenField. If it has single values then its works fine but if it has multi value then result is empty

What I have tried:

server side vb
<pre> HiddenField1.Value = "864180030063601,111111111111111"

Asp sqldata source

<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
                    ConnectionString="<%$ ConnectionStrings:xxxxxxxxx %>" 
                    SelectCommand="SELECT * FROM [table] WHERE ([column] in (@column))">
                    <SelectParameters>
                        <asp:ControlParameter ControlID="HiddenField1" Name="column" PropertyName="Value" Type="String" />
                      
                    </SelectParameters>
                </asp:SqlDataSource>

IN clauses are a special case in SQL: you can't pass them as a parameter, as the IN is converted to an internal table too early in the SQL command parsing sequence for parameter substitution.

See here: Using comma separated value parameter strings in SQL IN clauses[^]

Read it again: set up an SP and pass it the parameter.
