Question

How would i go about updating a single cell in a row so for example Row[0] i want to update the column “Value” with its current value +1. This is code i have which selects the single row but the Value updates with all the column “Value” data then +1

public void MetricChange()
    {
        DataTable dt = ds.Tables["MetricTable"];
        int value = dt.AsEnumerable().Sum(r1 => r1.Field<int>("Value"));
        if (Access.Checked)
        {
            ds.Tables["MetricTable"].Rows[0]["Value"] = value +1;
            //ds.Tables["MetricTable"].Rows[1]["Value"] = value - 1;
            Chart2.DataSource = ds.Tables["MetricTable"];
            GridView1.DataSource = dt;
            GridView1.DataBind();
        }

    }

How would i just update the “Value” column within a single row???

Answer 1

This is how you do it 😛

int val = Convert.ToInt32(ds.Tables["MetricTable"].Rows[0]["Value"]) + 1;

Then Update the row by this ds.Tables["MetricTable"].Rows[0][1] = val
