Datagridview - Sort Datagrid View Column With Numbers And Texts On Column Header Click?
Feb 13, 2012
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
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?
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. [code]...
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 have a VB 2008 connected to my localhost SQL using DataGridview, BindingSource and DataTable. All works fine, i can add, edit and delete the row and the SQL database is also affected.
However, there is one thing that bugs me, that is sorting.
Problem My table in this database is still quite empty, it only has 6 rows
However, if I spam-click the column header, the sorting seems taking some time to sort, so that, the sorting result does not follow my mouse spam-clickings
Note: Spam Click = Clicking the mouse button in high frequency, something like click click click click click click click click click, etc
I then make a debug button to check this
Variables: Dim DebugInt As Integer = 0 Dim bs As New BindingSource
I have a listview that has multiple columns. I am wanting to sort these columns when clicking on the column header.I see there is a sort function, but am not having much luck in using it.How can i sort my listview when clicking on the column header?
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 ??
in my application i created table called houseloading which has field called housename.which is inserted into the sqlserver database. my table will look like this
///column name house values red green
what i want now is i want to display the values red green as column header in datagridview
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?
i am curious and also would like to know how to duplicate this user interface feature in Windows 7. I am aware that if you attempt to sort a column in Windows XP, there is no up/down arrow in the column.
Please have a look at [URL]...It shows part of the task manager process list, and image name column is sorted in descending order.What i am trying to find out is how is the arrow pointing downwards (representing descending) is created.
Am i able to reproduce this "arrow pointing downwards" in VS 2005?
I have use this code to view my database into my datagird Dim dbPath As String = "Provider=Microsoft.Jet.Oledb.4.0; Data Source=../VG.mdb;Persist Security Info=False" Dim dt As New DataTable Dim ds As New DataSet Dim da As New OleDbDataAdapter da = New OleDbDataAdapter("Select * from Marriage", dbPath) ds.Tables.Add(dt) da.Fill(dt) Now every time I visit that form I have to manually click the column header of "EventDate" to that it will sort Descending. Is there a way to automatically sort it every time I visit this form?
I have a table with two columns, date and time. I am using the following code to sort in descending date order.
VB If historydataGrid.Rows.Count > 0 Then 'if there are rows, sort by date (most recent first) historydataGrid.Sort(historydataGrid.Columns(0), System.ComponentModel.ListSortDirection.Descending) End If
Where Columns(0) is the Date. However, how difficult is it for me to then sort secondarily by time. So that the grid will sort by most recent date and time.. Working down from the most recent time on the most recent date, and then moving backwards towards the oldest date with the oldest time.
I have coded my program so that when a user clicks on a column, the data is sorted in ascending/descending order.When I go to click on a column header, however, nothing actually happens.I dont get an error or anything.Here is the code that I am using to sort the records in the GridView:
Property GridViewSortDirection() As SortDirection Get If IsNothing(ViewState.Item("GridViewSortDirection")) Then Return SortDirection.Descending
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.
Still experimenting with datagrids and ran into another problem...I'd like to sort a column displayed in a datagrid bound to an Access table programmatically. The field is a date ime type and is sorted in descending order in Access. I can manually sort it at run time but i'd like to know how to sort it with code.
