How can I remove the first column in a datagridview. I mean the first column with the record pointer? I am using VB.NET 2005. Also I am not binding the control to any database.

I have a form that contains a datagridview, which is working properly. I want the user to locate specific records that are displayed in the grid. To that end, I have a sub that uses the datatable select method to find rows within the defined record set:
Dim
strFind
As
String[code]......
As far as I know this is working, as no exception is thrown.Is it possible to have the grid display this record if it is found without having to rebuild the grid?

View 1 RepliesI am trying to implement a DataViewGrid in VB.NET that will be simply for identifying and selecting GIS features that are already within a database. Simple enough with DataGrids and DataSets, although there is one slight twist.First, I need to be able to populate the grid based on one record of the column [Name] that is chosen from a ComboBox(I have been able to populate the ComboBox, but not the grid).Second, I need to restructure the DataGridView so that each current column name is in a column called "Field" and the row for that one record chosen is in another column called "Value".As you can see here, each "Field" is a column name and each "Value" is one record for each of those columns. So, if I could somehow parse through all of the column names into a "Field" column, and also populate a "Value" column with one record for each [Name], I would be on the road to happiness.

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?

Dim Comp = From C In db.Table1 _
Select C.Completed, C.Taken, C.Namne
Datagridview1.DataSource = Comp
Am using the Entity Framework and Columns Completed and Taken are of bit Datatype. When the query results are displayed in the datagridview, these bit columns are returned as of ColumnType Textbox - so i get a Datagridview textbox column with true or false string values.
I want to display Completed and Taken as Checkbox columns (either ticked for True or un-ticked for false) but ofcourse i can't do this in EditColumn dialogue because the Datagridview is unbound.
how can i change this in code at runtime

i have a date type column in my database and i have only kept the date in that but
when i use a select statement to get data it always comes with the time for example
in the database its only "12/30/2009 " but it always comes with "12/30/2009 12:00:00 AM"
" 12:00:00 AM" is attached with all the records but in the database its only "12/30/2009"
In my application I have several datagrids databinded to various tables. Within these tables I use many times a date field. The database is made in access. At the beginning I had the date format on default as long date. When I saw that time was added I changed it to shortdate. Still I get the time in the various datagrids. How do I remove the time from the datagrid so no time is entered when I create a new field.
