Hi Friends;

i want to select only one cell content of the row in the GridView regarding to the

CheckBox ;

(if Checkbox control is checked then select and add that cell text to the

StringBuilder )

but i couldnt do this (nothing returns to me)
help about this subject..

i've used this code

protected void LinkButton1_Click(object sender, EventArgs e)
    {
        StringBuilder str = new StringBuilder();

        for (int i = 0; i < gv.Rows.Count; i++)
        {
            GridViewRow row = gv.Rows[i];
            bool isChecked = ((CheckBox)row.FindControl("chkSec")).Checked;

            if (isChecked)
            {
                // Column 2 is the name column
                str.Append(gv.Rows[i].Cells[6].Text);
            }
        }
        Response.Write(str.ToString());
    }

When you say nothing returns to you: do you mean that isChecked always evaluates to false or that you do not get anything returned via this statement:

gv.Rows[i].Cells[6].Text

                    <ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" />
                </asp:TemplateField>
            </Columns>
        </asp:GridView>

There is no text in cell six all you have is a Checkbox:

<asp:TemplateField HeaderText="SELECTED">
                    <ItemTemplate>
                        <asp:CheckBox ID="chkSec" runat="server"/>
                    </ItemTemplate>
                    <ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" />
                </asp:TemplateField>
            </Columns>

What did you mean , there must be a text in it

No, there doesn't have to be. Cell six is the cell that contains your checkbox and you do NOT bind any data to that cell based on the code you have provided. As your code stands right now, you are trying to get text from the "SELECTED" column and, as I have said, there is no text there only a checkbox. Are you maybe trying to get data from a different column and typed '6' by mistake?

it looks like that i've written wrong index but after all i tried another indexes ; for example , {0,1,2,3,4,5} but nothing happened

Thats because you are binding to controls. Normally when you want to get the Text value of a cell, you simply call your databind method in the cell outside of a control like this:

                <asp:TemplateField HeaderText="SID">
                    <EditItemTemplate>
                        <asp:Label ID="lblID" runat="server"></asp:Label>
                    </EditItemTemplate>
                    <ItemTemplate>
                        <%# DataBinder.Eval(Container.DataItem,"SID") %> </ItemTemplate>
                </asp:TemplateField>

To do what you want without changing your code you can do something like:
protected void LinkButton1_Click(object sender, EventArgs e)
    {
        StringBuilder str = new StringBuilder();

        for (int i = 0; i < gv.Rows.Count; i++)
        {
            GridViewRow row = gv.Rows[i];
            bool isChecked = ((CheckBox)row.FindControl("chkSec")).Checked;

            if (isChecked)
            {
                Label lbl = (Label)row.FindControl("lblID");
                // Column 2 is the name column
                str.Append(lbl.Text);
            }
        }
        Response.Write(str.ToString());
    }
hth.
