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

updating multiple rows of a single column with different values at runtime from C#

Re: updating multiple rows of a single column with different values at runtime from C#

10-Nov-09 22:18

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 read that article and its really helpful.

My another question related to same issue.

instead of converting, is it possible to make richtextbox able to understand HTML.

like when we open open a file in IE(web browser).

Does same can be achieve for richtextbox control?

Its a window application.

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.
Sometime its a bloomer just for the Coding Horrors section. Laugh | :laugh:

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.

This question isn't really answerable is a forum environment. The description of everything you ahve to do would be a larger article or a small books worth. Far beyond the capacity of a few forum posts. All I can do is direct you to start researching the System.DirectoryServices namespace to get an understanding of the classes you're going to use to manipulate Active Directory. From there, you can come up with a design for your ASP.NET app.

Would you care to actually explain the problem and the code you're using or should we just guess at the million or so possible issues you have?
