Total of Selected Items in Gridview

Question

Hello

I have a Gridview

I have Click Button and two labels. (Risk_label and MV_label)

Risk and MV column has price value.

My Checkbox column names are NameCheckBoxField1 and NameCheckBoxField2

How can i calculate only "Which i selected in Gridview" Risk total and MV total in my labels?

Example;

Risk (Checked rows) --> 10, 20, 30 ---> Risk_label = 60
MV (Checked rows) --> 20, 30, 40 ---> MV_label = 90

EDIT: I try this code;

double sum = 0;
foreach (GridViewRow gvr in GridView1.Rows)
{
    CheckBox cb = (CheckBox)gvr.FindControl("NameCheckBoxField1");
    if (cb.Checked)
    {
        double amount = Convert.ToDouble(gvr.Cells[1].Text);
        sum += amount;
    }
}
Risk_label.Text = sum.ToString();

But i getting an error.

You didn't say what the error was though I imagine the difficulty is finding the checkbox in the row. The checkbox appears to be in the 9th cell of the row so I'd try to get it by index instead: double sum = 0; foreach (GridViewRow gvr in GridView1.Rows) { CheckBox cb = gvr.Cells[8].Controls[0] as CheckBox; if (cb != null && cb.Checked) { double amount = Convert.ToDouble(gvr.Cells[1].Text); sum += amount; } } Risk_label.Text = sum.ToString();
