I have a DGV that is populated at run time from a db query. One of the columns is sorted ascending and the column header for this column displays the little "up arrow" thing to signify it is sorted. I do not want the user to be able to click this (or any other column header) in this datagridview.
How can I maintain the column's visibility but disable the click function?
how do I get the Header text of the header the user clicked in the datagridview.I know I have to use the column header click event but I can't work out or find away to extract the clicked header data?
It seems that on clicking datagridview column header, the column will be automatically sorted based on the column type. I have a column showing some numbers. If column type is string, it sorts "1","20","3" into "1","20","3". If column type is double, it sorts into "1","3","20" which is the result that I want. However, there might be some erros in the numbers and error messages(text) will show in the cell instead of numbers. So I cannot set the column type as double. I want to ignore these error messages and sort all the numbers. How can I do this?
Also, I need to add some background colors to different rows in datagridview. So in the column header click event, I call the bkgColor Sub to achieve this. My question is that how can I override the sorting method in this event?
Private Sub DataGridView1_ColumnHeaderMouseClick(sender As Object, e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles DataGridView1.ColumnHeaderMouseClick Try
I have a DataGridView with SelectionMode = "CellSelect". I do this because I want the user to be able to click the Column Header and drag the column to a different DisplayIndex. They move the column by clicking and holding down the left mouse button, then moving the column. I also want the user to be able to click the column header and all the cells in the column would be selected. But if I change the SelectionMode property to "FullColumnSelect" or "ColumnHeaderSelect" the user can no longer move the column.In the code below, I can select all the cells in the DataGridView just fine, but I can't select all cells in a particular Column or Row.

I have a listview set up in Details View and I run a ascending/descending sort routine on the appropriate column when the user clicks one of the column headers.However, when I switch companies and reload the listview with new information, for some reason the event fires and I get an indexoutofrange exception as I believe that the information has not yet loaded when this fires.The e.Column property is set to that of the previous column which I clicked even though I have clicked nothing.
i want to disable double click to prevent WMP from change into full screen mode and i also want to disable right click to prevent WMP from showing option such as
i = dgStudentsHandled.CurrentRow.Index txtStudentNumber.Text = dgStudentsHandled.Item(0, i).Value
I can get the value of the first cell of the first row of the first column. But I have to get the value of the first cell of the the first column of the any row index I click.
I am currently working on my own listview control, and I was wondering if it was possible to get it to not draw the text for the listviewitem when the listview is in report mode? What I have been doing is putting all of my information in the tag and leaving the text property blank so it doesn't paint. Andis there a way to paint the background of the column headers? Because It only allows me to paint the actual column header? Here is what im talking about for the background of the column headers.
Can I show checkboxes to the column headers in datagridview for each column in my dgv I Used [url] for help but it replaces the header cells one by one .Can I use any property of dgv which shows checkboxes for all column headers
I have a windows application with many forms. We use the DataGridView control on most of the forms, but on a new form that I designed I have four DataGridViews. All of the DataGridViews on this form do not dipaly the Column Header Text when the form is displayed when running in the IDE. I do not receive any errors or messages. The other DataGridVeiws on other forms display their column header text just fine. I am at a loss as to why this is happining on this form.
UPDATE: If I add the desired text to the column.HeaderText property at the end of the form load event it displays the column header text. For example AssignedAmountColumn.HeaderText = "Amount" it displays Amount in the column when run from the IDE.... However it dosn't display when the property is set though the Columns property at design time.
Looking at deleting columns in excel and have found several threads that show how to delete an entire column which I have tested and done successfully. These columns were all identified by "A", "B", "C" and so on...
I was wondering if it was possible to do the same thing using the column headers. When deleting the columns in excel, one has to keep in mind that columns deleted from the left will shift the entire sheet to the left and if one is not careful, the next column[code]...
Let's say a user wants to delete the 'Middle' column (assume as column B in excel) and then delete the 'Suffix' column (assums as column D in excel). If they don't know to work from right to left when deleting columns, they would write code that would delete Column B and then repeat that code for Column D. However, once column B is deleted, all columns will shift left, which will result in the 'Phone' column (formerly column E now column D) being deleted instead of the 'Suffix' column (formerly column D now column C).
If there was a way to delete the columns by their headers (i.e. Middle, Suffix...) this would eliminate the problem; to me it seems a bit more intuitive as well.
I am reading a xml file and display all the data in datagrid view. But when I chose to display data of just one column only the data comes in the dgv but no column header. Same problem shows up, if I chose to display a particular row of a particular column. How can I fix this ??
I am trying to put the column headers from all the columns after the seventh one, in a listView. Columns 1 - 7 are working - I am putting the contents in textboxes, however I am struggling to grab the next columns and put the into the listfview. I am alsmost there, but something is not quite right: The first part is:
I currently have a DevExpress GridControl where one of the columns have a GridLookUpEdit assigned under ColumnEdit. Yet when I run there is a column name (the display member) that shows up.I know with a LookUpEdit you can set the column headers to invisible with lookupedit.Properties.ShowHeader = False but I have no clue how to make it invisible for the GridLookUpEdit.
VB Express 2010. ListView When I am in the ColumnHeader Collection Editor how do I create a column header and name it. Example: I wish my first column header to name DATE and when I reference this column in my code I wish to refer to it as DDATE. How do I use the ListView ColumnHeader Collection Editor to accomplish this task. I need a walk thru for the first column than I can use this to create my other columns.
Is there a way to implement a new column with a header in a checklistbox in vb.net? I've done a bit of searching, but didn't find much on the topic. Should I just abandon the quest and use a listview or some other control?
I am wondering if there is a way i can check if the listview header content is greater than the column conent if so autoresize based on that if not then resize by the column content.
I have a datagridview with several column header cells “merged”. I’m using the paint event to achieve the merged effect as shown below.
Private Sub tblEnv_Paint(ByVal sender As Object, ByVal e As PaintEventArgs) Handles tblEnv.Paint Dim brb As New SolidBrush(tblEnv.ColumnHeadersDefaultCellStyle.BackColor)
I have downloaded the VBWinFormDataGridView from the code framework, and implemented the code in to a project the only problem i have found is when i refresh or reload the information in to the column headers it increases the size and keeps doing this so the column headers take up the full form height.i understand that the coumn header height needs to be reset but unsure how to do this.
