使用VB在gridview中逐行访问单选按钮列表中的selectedValue [英] Access radiobuttonlist selectedvalue in gridview row by row using VB

问题描述

我在其中一列中有一个带有单选按钮列表的gridview.单选按钮列表由用户需要选择的是/否选项组成.我想逐行访问gridview以获取单选按钮列表的selectedvalue，但是我不知道如何一个一个地访问它.

任何人都可以帮助我吗?

这是我的gridview代码:

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:

<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>

我同意上面的回答，只是做了一点改进.
按照这种方式；

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.

}

以下是方法

Following is the way

foreach (GridViewRow gvr in GridView1.Rows)
           {

     RadioButtonList rb = gvr.FindControl("rb1") as RadioButtonList

string ans=rb.selectedvalue;
}
