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?
privateint nextIndex = 1; // used to label each buttonprivatevoid bAddButton_Click(object sender, EventArgs e)
Button newButton = new Button();
newButton.Text = nextIndex.ToString();
tableLayoutPanel1.Controls.Add(newButton, 0, 0); // first cell
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.
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 need to know How to edit and manage group policy through C# and ASP.Net application.I want to get all users an groups in the active directory and I already did this.I then want to assign group ploicy to groups and OU(organizational unit).
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.
i need the NewRowNeededEvent of the DataGridView. So i set the VirtualMode Property to true.
But if this property is set to true, i need to set the cell value by myself, otherwise it vanisches if i leave the cell.
So i've tried to save the value - the cell is a ComboBox where i select a value - in the CellValidatinEvent.
But it doesnt work. The value property of the cell is not changing it is still null.
Here is some code that you can understand what i mean.
privatevoid aufwandDataGridView_CellValidating(object sender, DataGridViewCellValidatingEventArgs e)<br />
DataGridViewComboBoxCell cell =<br />
aufwandDataGridView.CurrentCell as DataGridViewComboBoxCell;<br />
cell.ReadOnly = false;<br />
if (aufwandDataGridView.IsCurrentCellDirty)<br />
//e.FormattedValue contains the item thart i selected in the ComboBox<br />
cell.Value = e.FormattedValue;<br />
//cell.Value is not changing it is still null. no exception is thrown.<br />
