Populating a text box

[JonWB]

Hi,

I am very new to .Net and have recently taken over someone else’s project. I am developing an asp webpage using C#.

I have an asp:table that is populated using data from a database. However, there is also a column that contains checkboxes and a column that contains text boxes like so:

Location | Stock | Issue (checkbox column) | Issued (textbox column)

I want the user to click a checkbox and the value of the ‘Stock’ column for that row is then entered into the textbox of that row.

I have already populated the table with data and the user controls, I am only struggling with the event.

My code is shown below:

TableRow row = new TableRow();
                TableCell cellLoc = new TableCell();
                TableCell cellStock = new TableCell();
                TableCell cellIss = new TableCell();
                TableCell cellIssued = new TableCell();
 
                cellLoc.Width = Unit.Pixel(75);
                cellStock.Width = Unit.Pixel(75);
                cellIss.Width = Unit.Pixel(75);
                cellIssued.Width = Unit.Pixel(75);
 
                TextBox txtIssued = new TextBox();
                CheckBox issue = new CheckBox();
 
                cellLoc.HorizontalAlign = HorizontalAlign.Left;
                cellLoc.Text = location.Aisle + " " + location.Bay + " " + location.Level;
 
                if (matReq.Status >= MaterialRequisitionStatus.Picking)
                {
                    cellStock.Text = location.QtyRequired.ToString();
 
                    if (matReq.Status == MaterialRequisitionStatus.Picking)
                    {
                        if (userCanUpdate_)
                        {
                            issue.ID = "cbIssue_" + location.ProductCode + "_" + n.ToString();
                            string box = issue.ID;
                            issue.AutoPostBack = true;
                            cellIss.Controls.Add(issue);
                            txtIssued.Width = Unit.Pixel(50);
                            txtIssued.ID = "txtIssued_" + location.ProductCode + "_" + n.ToString();
                            txtIssued.Style.Add("text-align", "right");
                            cellIssued.Controls.Add(txtIssued);
 
                        }
                        else
                            cellIssued.Text = "-";
                    }
                    else
                        cellIssued.Text = location.QtyPicked.ToString();
                }
                else
                {
                    cellStock.Text = location.Stock.ToString();
                    cellIssued.Text = "-";
                }
 
                row.Cells.Add(cellLoc);
                row.Cells.Add(cellStock);
                row.Cells.Add(cellIss);
                row.Cells.Add(cellIssued);
 
                tblStock.Rows.Add(row);

This is my first post, so I hope I have given enough information for you to understand what I am attempting to do.

Thanks in advance,

Jonathan.

Have you tried the OnCheckedChanged event?

[JonWB]

Thank you for your reply. I have tried OnCheckedChanged event with no success. I have been trying to use both the AutoPostBack and javascript in the following ways

if (matReq.Status == MaterialRequisitionStatus.Picking)
{
if (userCanUpdate_)
{
issue.ID = "cbIssue_" + location.ProductCode + "_" + n.ToString();
string box = issue.ID;
issue.AutoPostBack = true;
cellIss.Controls.Add(issue);
txtIssued.Width = Unit.Pixel(50);
txtIssued.ID = "txtIssued_" + location.ProductCode + "_" + n.ToString();
txtIssued.Style.Add("text-align", "right");
cellIssued.Controls.Add(txtIssued);
if (issue.Checked == false)
txtIssued.Text = cellStock.Text;
}
else
cellIssued.Text = "-";
}

and using javascript I replaced the if (issue.Checked == false) statement with:

issue.Attributes.Add("OnCheckedChanged", issue.ClientID + "javascript:_popbox(cbIssue_" + location.ProductCode + "_" + n.ToString() + ", txtIssued_" + location.ProductCode + "_" + n.ToString() + ", " + cellStock.Text + ");");

with javascript:

function _popbox(check, txt, val)
{
if (check.checked = true)
{
txt.Text = val;
}
}

I haven’t been able to get either method to work. Do you think that either of these ways are possible?

Thanks,

Jonathan.
