• Paulustrious (VS2003)Owner Drawn Listview Item Height

  How do you set the item height of an ownerdrawn listview in 1.1Framework Our target framework is 1.1. I know that ownerdrawn listview is available in 2.0, but we are not currently keen to moving to 2.0 as of now because of business reasons. I need to create a listview with variable item height in report/detail view. What message should I send to set the desire height of the listview item. Just to set the general item height will be a start. Has anyone done this   My custom listview is an implementation of virtual listview. The listview doesn't really have an item collection. Most drawing are done using the API calls. For some reason even when the MEASUREITEM event is ca ...Show All

• Tom_Liu DataGridView Refresh issue

  Hi I currently have a dataGridView that is responsible for displaying all of the data from a table within my database. Whenever the table is altered thru another form, the changes doesn't get reflected in the dataGridView until I close and reopen the program. I tried to use the Refresh() method but it seems the compiler does not detect anything new to redraw. I also tried to Invalidate() and redraw the grid, but that doesn't work either. Does anyone have any idea on how to refresh a dataGridView Thanks for your time in advanced. Hi, I found the same problem of refreshing, and this solution worked fine for me. The problem is that when refreshing, after comming back from the child form, the cursor i ...Show All

• dwloeb77 Embedding Open File dialog

  Hi, i want to add an open file dialog control to my program. But want it to be seen always, not close after DialogResult. Is this possible If you are using FrameWork 2.0, it should be possible this .openFileDialog1.FileOk += new CancelEventHandler (openFileDialog1_FileOk); void openFileDialog1_FileOk( object sender, CancelEventArgs e) { string name = this .openFileDialog1.FileName; e.Cancel = true ; } e.Cancel = true will not allow the dialog to be dismissed. Not without jumping through some creepy hoops. OpenFileDialog.ShowDialog() disables your other forms. You could possibly avoid that by calling ShowDialog() in another th ...Show All

• gafferuk Label within a label? C# and .NET

  Hi guys. I have an interesting issue. I have labels created dynamically at runtime in my app, and placed in a flow panel. What I need is for some of those labels to have an extra label with a single digit placed in one corner. What I have so far done is created a class which derives from a label AND has a label in it. i.e. class Slide : Label { public Label l_IndexLabel; public Slide() { l_IndexLabel = new Label(); } public void SetUpSlide() { l_IndexLabel.Text = this.Tag.ToString(); l_IndexLabel.Size = new System.Drawing.Size(10, 20); l_IndexLabel.BorderStyle = BorderStyle.FixedSingle; l_IndexLabel.Location = new System.Drawing.Point(this.Right - 10, this.Top + 20); l_IndexLabel.Show(); l_IndexLabel. ...Show All

• Spicer650 Initialise a cell in a new row

  Hi there When a user creates a new row in my datagridview, I'd like to initialize one of the cells to a pre-determined value, programatically. I tried using the UserAddingRow event, but it seems to change the row after the row that is being edited. Ideally, I would like to initialize the cell before the new row is visible. Any thought welcome. Cheers Dave Hi, Perhaps you could try the DefaultValuesNeeded event of the DataGridView. Here's a sample from MSDN: private void dataGridView1_DefaultValuesNeeded(object sender, System.Windows.Forms.DataGridViewRowEventArgs e) { e.Row.Cells["Region"].Value = "WA"; e.Row.Cells["City"].Value = "Redmond"; e.Row.Cells["PostalCode"].V ...Show All

• nbrege How can we achieve Scroll lock type functionality in text box Or Richtextbox (c#)

  I have a multiline textbox/RTB where text is appended every 20 ms. I want to copy some text in between and see what i have received. But whenever I click on RTB, It scrolls to down and I am not able to copy related text. So How can I achieve scroll lock functionality. I want the same behaviour as dot net IDE output window where text keeps on appending but whenever we want to copy it allows us to do. I was just messing around with stuff in VS2005 and the output window doesn't do what you say. When new text is added the output window automatically scrolls to the bottom. Which would be the same as using AppendText() on a textbox. I understand what you want, but I don't know of a way (if there even is a way) to do what you want. EDIT Ok ...Show All
