Mergeing On-Click events in Code-Behind

Hi,

I'm adding a button to an existing app. I need to open a new window once this button is clicked. The new button has been added to an existing User Control and takes on all the attributes of the other buttons. Great.

I need to add an onClick event to my button in the code behind that will open a new browser via some javascript (window.open). When I add it it and run the code it renders the button with 2 onClick events (1 from the global attributes of the user control I guess) My onClick doesn't funtion (not a shock) I know I can have 2 functions running on 1 onClick - I separate with a semi-colon - how do I merge my onClick event into the existing one? Attribute.Add("onClick"),myButton creats a new one.

Any ideas welocme !!

Thanks

Get the network mask of your current IP, then enumerate through all the combination's in your subnet pinging each one for a response.

If you have no idea what I am talking about, read up on how IP networks work.

Hello everyone,

When executing !bpmd command in WinDbg, there is error like this, any ideas?

(there is no such error, if I start to run the application, and break in the middle of running, then type !threads again. My purpose is to use !bpmd command to set breakpoint before the application runs, so this situation makes me inconvenient.)

0:000> !bpmd
Failed to find runtime DLL (mscorwks.dll), 0x80004005
Extension commands need mscorwks.dll in order to have something to do.

thanks in advance,
George

Sounds like .NET is not installed, or in your PATH.

Thanks leppie,

.Net is installed. Do you mean the %PATH% when you say "in your PATH"? If yes, could you post your %PATH% please? I want to check whether mine is correct by comparing with a correct one.

(BTW: if not using Windbg, my C# application can run without any issues, so I do not think it is PATH issue, anyway, it is good to check the PATH with you to learn something more.)

Hi, i got a datagridview and the column ID 6 is a column which shows the price and columnID 0 have a checkbox.

How do i calculate the price when the check box is ticked or unticked.

I tried at a timer with interval of 1 second to check

private void timeCountPrice_Tick(object sender, EventArgs e)
{
    double price = 0.0;
    foreach (DataGridViewRow dgw in dataGridProduct.Rows)
    {
        DataGridViewCheckBoxCell datacell = dgw.Cells[0] as DataGridViewCheckBoxCell;

        try
        {
            if ((bool)datacell.Value == true)
            {

                price += Convert.ToDouble(dgw.Cells[6].Value.ToString());
                lblTotalPrice.Text = "Total Price : $ " + price;
            }
        }
        catch (Exception exc)
        {
        }
    }
}

You could subscribe to the DataGridView's CellClick event, so that you know when a cell's actually been clicked. Inside the handler you get told the row and column so you can work out if it's a checkbox cell, then update your totals accordingly.

Okay, 1 more question

I have a form called ModifyOrder. Basically my form have 2 hashtable. I called orderTable and the other is productTable.

My orderTable stores an Order object. Below is my class for Order.cs

namespace EBMS
{
    public class Order
    {
        private string refNumber;
        private string custName;
        private string destAdd;
        private string destCity;
        private string orderDate;
        private double totalPrice;
        private Hashtable itemList;

I got a attribute which store a list of items( from the productTable) into a hashtable called itemList inside my Order class

I have a datagridview which shows all the record i have in my productTable and the first columm of the datagrid is a checkbox.

When the user enter the Order's Ref Number to be modify, the datagrid wil show all the productTable. I want the first column(checkbox) to be checked if the product exists inside the Order class itemList.

How do i go about it?

I tried this code, but it does not tick the checkbox

if (orderTable.ContainsKey(tbxSearchRefNum.Text))
{
    tbxRefNumber.Text = ((Order)orderTable[tbxSearchRefNum.Text]).RefNumber;
    tbxCustName.Text = ((Order)orderTable[tbxSearchRefNum.Text]).CustName;
    tbxCity.Text = ((Order)orderTable[tbxSearchRefNum.Text]).DestCity;
    tbxAddress.Text = ((Order)orderTable[tbxSearchRefNum.Text]).DestAdd;

    this.dataGridProduct.Rows.Clear();
    int currentRow = 0;
    foreach (Product p in productTable.Values)
    {
        this.dataGridProduct.Rows.Add();
        this.dataGridProduct.Rows[currentRow].Cells["colProductName"].Value = p.Name;
        this.dataGridProduct.Rows[currentRow].Cells["colModelNumber"].Value = p.ModelNumber;
        this.dataGridProduct.Rows[currentRow].Cells["colCategory"].Value = p.Category;
        this.dataGridProduct.Rows[currentRow].Cells["colDesc"].Value = p.Description;
        this.dataGridProduct.Rows[currentRow].Cells["colMSRP"].Value = p.MSRP;
        this.dataGridProduct.Rows[currentRow].Cells["colRetailPrice"].Value = p.RetailPrice;

        foreach (DataGridViewRow dgw in dataGridProduct.Rows)
        {
            DataGridViewCheckBoxCell datacell = dgw.Cells[0] as DataGridViewCheckBoxCell;
            try
            {
                Order newOrder = new Order();
                newOrder = (Order)orderTable[tbxRefNumber.Text];
                uint modelNumber = Convert.ToUInt32(newOrder.ItemList[p.ModelNumber]);

                if (dgw.Cells[2].Value.ToString() == Convert.ToString(modelNumber))
                {
                    this.dataGridProduct.Rows[currentRow].Cells["colSelect"].Value = true;
                }

            }
            catch (Exception exc)
            {
            }
        }
        //MessageBox.Show(dataGridProduct.Rows[currentRow].Cells["colSelect"].Value.ToString());
        currentRow++;
    }

}
