Hi,

I have a gridview with a radiobuttonlist in one of the columns. The radiobutton list consist of Yes/No options where the users need to choose. I want to access the gridview row by row to get the selectedvalue of the radiobutton list but I do not have any idea how to access it one by one.

Anyone please help me?

This is my gridview code:

XML

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
        DataKeyNames="QuestionNo" DataSourceID="SqlDataSource1">
        <Columns>
            <asp:BoundField DataField="QuestionNo" HeaderText="QuestionNo" ReadOnly="True" 
                SortExpression="QuestionNo" />
            <asp:BoundField DataField="Question" HeaderText="Question" 
                SortExpression="Question" />
            <asp:TemplateField HeaderText="Answer">
                <ItemTemplate>
                    <asp:RadioButtonList ID="rb1" runat="server">
                        <asp:ListItem Value="1">Yes</asp:ListItem>
                        <asp:ListItem Value="0">No</asp:ListItem>
                    </asp:RadioButtonList>
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>

I agree with answer above, just a little enhancement.
Follow this way;

foreach (GridViewRow row in GridView1.Rows)
{
    RadioButtonList rbSelect = (RadioButtonList)row.FindControl("rbl");
    ////TO DO: Write the required code.

}

I could have provided this code in VB.Net, but we'll make it more easy, just follow this link below;

Following is the way

GridviewRow gvr=GridView1.Rows[GridView1.SelectedIndex];
RadioButtonList rbl=gvr.findcontrol("rb1") as RadioButtonList ;
string result =  rbl.SelectedValue;

Hye sekharkaza. Thanks for your quick response.

Can it loop until the last row? I have about 40 rows inside the gridview where each row i will analyze the Yes/No answer.
