I have a datagrid control in my winform application. It has nearly 30 columns. First 2 column are frozen and others can be views using scrollbars.

View 8 RepliesI've got a DataGridView that has a DataTable as it's Datasource. Whenever I sort a column and then edit a cell, after editing the column, the column autosorts so the recently edited cell is no longer in the viewable area.

Heres my problem, My app outputs info into a textbox as a log and appends the new lines to the end of the textbox, is there a way i can scroll the textbox so it displays the end of the text? I had considered writing the line at the top and appending the rest of the data to it but the line is hard to do this way (it uses info from 2 seperate subs and would need a global or a new textbox) and ideally i would like the info at the end in chronological order. the textbox is refreshed at the end of each entry.
View 2 RepliesWell un-like the textbox when AppendText() is used, the box doesn't auto-scroll down to the end, now I already know about caret position scrolling & all that but if I use it it seems to scroll slightly past the endline about enough to show yet another line if there were one.Now I was going to use code from a post I had inquired about similar but it's not working here in vista(SendMessage function) isn't functioning at all, it says the endpoint wasn't found, I guess meaning the function in the .dll wasn't found to be used.url...It was originally for a textbox to retain position if your not scrolled down to the bottom, which I want to keep such functionality in a RichTextBox but make it scroll to the bottom otherwise(hopefully not the slightly too far problem I have with caret position now...)

View 2 RepliesI have added three columns to the ListView control,
listView1.Columns.Add("id", listView1.Width / 3); listView1.Columns.Add("Name", listView1.Width / 3); listView1.Columns.Add("Address", listView1.Width / 3);
Assume the ListView1.Width is "30", then each column should be in event width of 10. Furthermore thereshould only be three columns becuase i have added only three columns. However, when i resize teh form, the listview controls shows an additional column.
How this was added? How do i fix this, so that when i add 3 columns it will have only three columns even when resized the form or not

View 4 RepliesHow can I create a fixed row in my DataGridView. I am populating the grid in code row by row.
View 1 RepliesI'm having a problem where I have elements such as Listboxes and Rich Text boxes that I want to set to size automatically in xaml according to the size of the window, but I only want it to resize to the size of the window and then put scrollbars if the content is any bigger than that.
Unfortunately, the only way I can get scroll bars to work is if I set a specific height of the listbox/rich text box (which does not work because I want it to automatically resize to the height of the grid that it is contained within, which is generally the height of the window (auto).
A panel with enabled scrollbars has many buttons. If I push the tabulation key, focus navigates between buttons.When a partially visible button has focus, the panel scrolls itself in order to completely show the button.

View 2 RepliesI need to limit a Textbox and DataGridView to only enter text in the fixed size of the cell/textbox on the screen. So I have limited the cell/textbox so user can not change it size. Both allow multiline and wordwrap. cell/textbox is sized to accept 5 lines of data (wordwrap or enters) This is like an online form.So the text enter will be printed so I can not allow scrolling in the cell/textbox.
How can I stop the scrolling of the text inside the cell/textbox.
Also : if the user Paste into the cell/textbox how to truncate text if larger than display area.
sample settings:
DataGridView1.AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.None
DataGridView1.AllowUserToResizeRows = False
