    <p>I am just want to check for empty text boxes and change the text the boxes if they are null in RowEditing event. I just can't figure this out. Of course the some of the boxes will be empty when the Grid is populated. The other question is am I placing this in the right event? </p> <p>Here is the row editing event :</p> <pre><code>protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e) { fill_grid(); //Set the edit index. GridView1.EditIndex = e.NewEditIndex; //Bind data to the GridView control. check_grid_boxes(); GridView1.DataBind(); } </code></pre> <p>Here is the check_grid_boxes Method : </p> <pre><code>protected void check_grid_boxes() { if (gtxtLane.Text == "") { gtxtLane.Text = "0"; } else if (gtxtCarriers.Text == "") { gtxtCarriers.Text = "0"; } else if (gtxtREV.Text == "") { gtxtREV.Text = "0"; } return; } </code></pre> <p>Before you mention Java Script or Jquery. This is a web control and my attempts at using java has not worked. </p> <p>I changed my code to this : </p> <pre><code> protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e) { fill_grid(); GridView1.EditIndex = e.NewEditIndex; var lane = (TextBox)GridView1.Rows[e.NewEditIndex].FindControl("gtxtLane"); var car = (TextBox)GridView1.Rows[e.NewEditIndex].FindControl("gtxtCarriers"); var badcar = (TextBox)GridView1.Rows[e.NewEditIndex].FindControl("gtxtBadCarriers"); if (String.IsNullOrEmpty(lane.Text)) { lane.Text = "0"; } else if (String.IsNullOrEmpty(badcar.Text)) { badcar.Text = "0"; } else if (String.IsNullOrEmpty(car.Text)) { car.Text = "0"; } GridView1.DataBind(); } </code></pre>

    3. COThe check_grid_boxes method is throwing the exception. I was thinking the way I close the If statements is is wrong with just using return?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
