I have a spreadsheet that I need to trim 3 columns. I have scoured the net but can't find anything that I've been able to use to trim each cell in columns A, H and I. I am using Excel 2003 and VS2005.
View 1 RepliesI would like to update an Excel cell using the cell name, such as "A1", instead of using the row and column, such as (3,2). I haven't been able to do it. Here is the code I used to update the cell by row and column. How would this code be updated so that it updates the cell by cell name instead?

In VB.NET, using Interop.Excel, I need to access a cell based on a row number and column letter. I tried my luck with...
pages.title = DirectCast(wksht.Cells(rows, "D"), Excel.Range).Value
Since the parameters took type object, I figured maybe this would work, but got no luck. I also thought of enumerating each letter to a number, but the columns in the spreadsheet aren't as normal. Meaning, they're not
A B C D E F G
They're actually...
A B C D E T AZ
I don't know if this makes a difference in the numbering of the columns. The question should be obvious, but just to reiterate, how can I get a cell based on a row number and column letter?
I have code that will plus Row but need help with pluse column.Full code snippets:

VB.NET code to change Excel 2007 Column Cell Format from Text to a Number no Decimal.
Right now Column F shows values that look like
3E+13
3E+13
Manually changing it to a Number with No Decimal shows the correct value.
30000046605562
30000041582875
Of course I would like to automate this.

I'm using something call ultragrid in my program.The program works as a mini-record keeping area (Like any datagrid, really). Well, I am adding a history to it and it allows the user to see the last 50 records searched. They get a grid showing the records. This, thus far, works perfectly What I want to do is this: I want to select a record (A cell) in the column 'Dog and have the text of that cell appear in a textbox. This is what I've tried with no success.

I'm attempting to copy cells, one at a time, from an Excel 2003 (or 2007) spreadsheet to a Word 2003 (or 2007) table. I'd like the code to be version-agnostic, and so am using late binding. The formatting of the contents of the Excel cell, such as color, underline, strike-through, needs to be preserved. My approach is to use a Word doc as a template. It has a table at the top which I can copy to the end of the doc, add rows as needed, and fill in the word table cells with the data from the excel spreadsheet. Unfortunately, all the formatting disappears. All I get is the text itself.

View 7 RepliesI'm trying to create a datagridviewrow and add data to it at runtime. I want the row to have the cells correspond to the columns in a datagridview, so that when I add data to the cells i can call the column name (the columns are likely to change around, so i think the name is better to use then the index).I create the row using the following code:
Dim row As New DataGridViewRow
row.CreateCells(Datagrid)
and the column using the following code:
Dim col As New DataGridViewComboBoxColumn
col.HeaderText = "Reference"
col.Name = "Reference"
datagrid.Columns.Insert(0, col)
I would like to add data to the row via the following code (or something similar that uses the column name instead of the index:
arow.Cells("Reference").Value = Detail.Reference
However at runtime I get the exception Column named Reference cannot be found. Parameter name: columnName I have a sneaking suspicion that the cells cannot be accessed with the column name because the row isnt really attached to columns yet (the row hasnt been added to the datagridview yet. (I tried cloning the cells of a row and then adding them to the row but no success)?

I believe that my questions are all going to revolve around the internal workings of DataGridView.While this is specifically written in VB.Net, it is definitely a general Visual Studio object question generically related to anyone working with .Net.I've been trying to find a forum where I can get some interaction and help to move forward.Microsoft's websites seem to be all questions and no answers.
I'm using VB.Net under Visual Studio 2005 SP2.I need to have a DataColumn that is dynamically visible based on other data in the same DataRow.After a lot of unsuccessful testing with various methods of accomplishing this, I came across the concept of Custom Cells/Columns.I started with several slightly varying examples and everything seemed to be falling into place. I tried to research each property and attribute as I incrementally learned a lot about the internal workings of Windows controls in general and DataGridView in particular.
The confusing symptom is that as I scroll down through the grid, the painting of the custom cells is at best unreliable.I created a minimum test case to eliminate as many variables as possible and I combined all of the source into one Form1.vb as follows:

i am developing an application in VB.net implies some datagridview operations. the appl contains one DGVW with columns fixed programatically, one such column is Datagridviewcheckbox column. the datasource for dgvw is bounded by a datatable. the user needs to enter the values in the GUI.
supposing the user enters the 2x2 matrix values, and the user checked the checkbox last cell in the dgvw. The problem - the last cell value is not updating inside. if ii debug through code, the "cell(2,2).value" reurns null value whereas the rest of them returns the value what i entered.
if i clicked the mouse some where in the dgvw after entering the last cell value, then it is returning the exact value as expected.
I'm trying to render a checkbox in a datagridview column header so that when the checkbox is checked/unchecked all the cells in that column should be checked/unchecked accordingly.The datagridview is bound to a database table but the column containing the checkbox header cell is unbound. The problem is, whenever i click the header checkbox, all the cells in that column are checked but the header checkbox itself gets invisible. If I click the HEADER (though the checkbox is invisible, still I can click the header) again, all the cells in the column below are unchecked and the header checkbox becomes visible and unchecked. Everything is happening as expected except the visibility of the header checkbox. Why is it so?

i am developing an application with vb.net incorporating a Datagridview control. i know that we can make a particular column as checkbox column or text colum or button column. Is there any property/method to make one cell as checkbox cell, other as text cell and another as buttton cell for particular column within the DGVW?

View 2 RepliesI have a DataGridView that based on certain conditions certain columns or rows or cells need to be locked/disabled but the data in the columns or rows or cells needs to bvisibleNow let me define what I mean by lock/disable; the user cannot click on any cell that islocked/disabled, if the use is using the arrow keys the selected cell cannot move to a locked/disabled cell.So this means that setting the cell as read only will not work, the user can still place the cursor on that cell.
