Apr 12, 2009I am using VB.Net 2008 and have build a windows form with a datagridview that displays a query of records for the current client. One of the columns is for Fee. I need to total that column and place the result in a Label or Textbox. I am using the Query builder to pull the records and so I can not get away with the SQL expression in the query returns the Schema does not match error. I have tried to code it pulling the information directly into the form from the Datagridview and could not make that work either.

Aug 11, 2010Right now when I need to refer to a cell to update the text I do it this way:
DG1.Rows(intRow).Cells(1).Value = "Hello!"
Is there a way to use the column name for column #1 rather than the number? This way if I decide to add columns later in an update and it's not at the end of the current columns, I do not have to re-number all my code. I tried searching but must not be looking for the right keywords.

View 3 RepliesVS 2008 DataGridView Column Scrolling?
Apr 22, 2009A program I am making required that I write my own code for column reordering rather than using the built in column reordering in the datagridview control. When I am dragging a column my code checks if the cursor is near to the right hand side of the control and if so it scrolls to the right using firstDisplayedColumnIndex.
The problem I am encountering is caused by the fact that when I do my custom dragging of columns the display index is changed not the column index itself.So when my code tries to scroll to the right using firstDisplayedColumnIndex once it reaches the very right it jumps back and forth. This only happens when I have moved the first column and thus when the first displayed column doesn't have the lowest index.
VS 2008 - Search Item By DataGridView Column
Jan 14, 2010Data in Table1 is as follows
Code-------product--------weight
1-------------Apple----------2.00
2-------------Mango---------3.25
3-------------Banana---------6.50
Then I have Datagridview with three columns same as
Code, Product, Weight
I have following codes
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
str = "SELECT desc1,weight FROM master where code =" & Val(DataGridView1.Rows(0).Cells(0).Value)
dt = GetTable(str)
If dt.Rows.Count > 0 Then
DataGridView1.Rows(0).Cells(1).Value = Trim(dt.Rows(0).Item(0))
DataGridView1.Rows(0).Cells(2).Value = Trim(dt.Rows(0).Item(1))
End If
End Sub
When I enter 1 in row(0).cells(0) then other two columns fill automatically, but when enter 2 in next row then nothing retreived from database.I think this line should me modified as current row and current column.
str = "SELECT desc1,weight FROM master where code =" & Val(DataGridView1.Rows(0).Cells(0).Value)
VS 2008 : Removing A Checkbox Column From Datagridview?
Nov 10, 2009I have a userform which allows my users to go through numerous comboboxes to select a combination of items they want displayed in a datagridview. My datagridview is populated from sql queries to my database(s), depending on the choices made in the comboboxes. The first column has checkboxes so my user can pick which rows they want to keep. Once they've chosen what they want, they click a button to save those rows into a seperate sql table.
All this works well, but here's my problem. After they click the button to save to the table, or another button which simply clears the datagridview without saving to the table, I want to clear my datagridview. While it seems to work, after all my comboboxes are cleared, and I go through another iteration of choices, and I display all the rows again in the datagridview, I get a second column of checkboxes.
Right now the checkbox column is added right before the datagrid's datasource is set. I've tried adding this column outside the subroutine that populates the grid, but it doesn't work.And I've tried numerous ways to delete this column so it will be regenerated when the datagridview is repopulated. Different things either give me errors or bomb when I compile.how to remove a checkbox column from a datagridview for good?

VS 2008 DataGridView Set Column Forecolor Headache
Apr 13, 2010I've found my life greatly eased by having given up on ListView. DataGridView is by far the better way to go. I wish I listened early on to the suggestion of someone here who recommended it. Chalk up another failure to my stubbornness.However, while I can set the ForeColor of an individual cell using GridV.Item(a, b).Style.ForeColor,[code]All these work without a hitch. But when I want to set the text of a given column to a desired color, GridV.Columns(a).DefaultCellStyle.ForeColor is completely ignored.Upon investigating further, I discovered that exactly the same behavior as described above is also true for setting the text and back color for Rows.If I have to, I'll succumb to using GridV.Item(a, b).Style.ForeColor, though this adds unnecessary complication to the code. But I'd like to know why I'm unable to set the text color of a column or row programmatically and get that working.
