Hi,

Does anyone have idea on how to create a few radio buttons using data from XML file?

I would like to have the buttons to be created once I load the form. But I do not have any idea as I started learn about XML today.

Thank you in advance. Smile | :)

Well.. just parse the XML document (plenty of tutorials online) and find the elements representing the radio buttons. And in your Form_Load event you create the buttons and add them to the Form. Good luck!

TableLayoutPanel Problem

Can't work out what I'm doing wrong. When I programmatically add a button to the first cell of a table layout panel by calling 'tlp.Controls.Add(newButton, 0, 0)' it works the first three times, shifting existing controls along a cell as expected. However after the third time the same code inserts the button into the second cell a few times, then after more calls, the third etc. Examlpe code below.

Is there a limit on how many times you can call Controls.Add(ctrl, column, row) for a given cell?

private int nextIndex = 1; // used to label each button
 
private void bAddButton_Click(object sender, EventArgs e) 
{ 
    Button newButton = new Button(); 
    newButton.Text = nextIndex.ToString(); 
    tableLayoutPanel1.Controls.Add(newButton, 0, 0);  // first cell
    nextIndex++; 
}

Thank you for your quick reply. However I only want one button per cell for scaling reasons.

Hello

I am working on examination project. I hava a column Position in Database. I am storing position in this column on the basis of obtained marks.suppose that i have entered 50 students record and assign each student a position on the basis of obtained marks. now i enter 51 number student and the obtained marks of this new student are higher than all students,definitely i will assign 1(ist position) to this student and all other students Positions will be changed. A student who is on ist position before entering 51 student record will changed from ist to 2nd position and rest of students positions also changed.

Now when i use update command from C# it only updates one row and left other rows to old values. i am using update in a loop.

And only a single row which is updated is of those student who has less marks than new 51 number student and rest of the rows are not updated.

Plz reply immediate

Thanks

Nobody is going to reply if you post a question with this.

How about posting the update code and we can see where the problem is. For starters I would re-evaluate the whole order. Just updating/adding the one student would not "auto" update the rest of them. Post the code you use for the update and we can check or advise from there.

Excellence is doing ordinary things extraordinarily well.

I am using:

<br />
foreach (DebtorDataSet.PaymentArrangementsRow row in debtorDataSet.PaymentArrangements.Rows)<br />
                                {<br />
                                    if (row.PaymentArrangementID != -1 && row.PaymentTypeID == Convert.ToInt32(paymentCategoryComboBox.SelectedItem) && row.ArrangementComplete == false)<br />
                                    {<br />
                                        row.ArrangementComplete = true;<br />
                                        row.ArrangementDate = DateTime.Today;<br />
                                    }<br />
                                }

but this is giving me the error:
'Unable to cast object of type 'System.Data.DataRowView' to type 'System.IConvertible''
I am not sure how to correct this.

Any help would be much appreciated please.

I'm not really sure about it, but because there is only one line where you convert something I would
replace

Convert.ToInt32(paymentCategoryComboBox.SelectedItem)

with

Convert.ToInt32(paymentCategoryComboBox.SelectedItem.ToString())

But in general SelectedItem is not from the type 'System.Data.DataRowView' so I'm a little
bit confused with it. But maybe that helps.

Many thanks for your reply.

Sill me realised that I needed SelectedValue instead of selectedItem to do the job.

On the other hand its sometimes very funny to look over code you wrote in a stressful time.

What type is the SelectedValue?
If it's an int, why convert an int to an int? Just cast it.
If not, then you can probably cast it anyway.

I find the Convert class to be nearly entirely useless; try not to use it.
