Is There A Way To Edit Columns And Rows Manually
Feb 25, 2011
I am using Datagridview to show some table data from database. It is working but its appearance is not what i am looking for. Is there a way to edit columns and rows manually ?
This is a list of what i want to do :
1. First of all i want to change column captions. because they are like "Fld_name" etc.
2. There is a column that shows date. I want to write a code for it ( convert date type )
3. I want to add a button at the end of each row and write a code for it ( show detail about that record )

I have Dataset ds filled up with values Until now I was displaying values in GridView. Now I want that all the rows should be columns and columns should be rows.I have 2 options: Either 1 I can directly convert grid to columns and display it, or 2 I can convert the GridView to html and then write loops to convert. I was trying the 2nd option but I cant figure out how I should do that.[code]With this code I am still getting same as GridView. Please help me for converting rows to columns and vice versa.

I have a form to edit data, with a manually created navigator.Everything works, including the record movement, saving and cancelling changes, etc.My question is...how can I detect if there have been changes to the current record prior to moving to a different one?If the user has made changes to the current record and tries to move to a different record without saving them, I want to prompt him to save.All of the events I've found don't detect a changed record until AFTER the change record has occurred.I assume that typing something in any of the text boxes has to implicitly call the beginedit method.Does that not set a flag or generate an event I can use to set my own flag?
I've looked around here and seen stuff about capturing key down events, looping through the text boxes, etc.Is something this normal really that difficult?If I wanted to write 50 lines of code to do stuff I'd be using C instead of VB.I'm switching from Delphi to VB because Delphi costs $2500.But if I have to spend 5 times as long trying to do standard stuff like this...maybe I need to rethink that choice.

I need to set some of the columns in a DGV to specific widths. What I am looking for is to line the columns up with the labels above them. I am trying to do it like this(the numbers are just for testing):
Me.DataGridView1.DataSource = dsForm.Tables(0)
' column 6
Me.DataGridView1.Columns(6).Width = 100
[Code].....
what I might have to change in the properties of the DGV for the code to set the widths, I've changed so many that I am not sure what the default settings are any more. Also the look of the form is not open to suggestion as this is what the customer wants.

I'm adding rows to a DataGridView via the following function, passing in one or more DataTables.The DataGrid is not aware what column(s) are coming back, but appears to build the column names okay.It's when it adds the individual cells (highlighted) that I get the following message:
ArgumentOutOfRangeException was unhandledSpecified argument was out of the range of valid values.Parameter name: rowIndex

I am stuck on how I go about using the nested for loops.Add code in the Draw button�s Click event to create the number of rows and columns selected, using the character selected Use nested For loops to create the rectangle of characters based on the user selections. The outer loop will control the number of rows. Use the value selected in the Rows combo to determine the stopping value of the outer loop. Use the value selected in the Columns combo to determine the stopping value of the inner loop, which controls the number of characters per line.
Public Class MainForm
Private Sub MainForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I'd like to copy some rows of data from a data-bound datagridview to a different datagridview.I thought adding a row would just be like this: [code]The trouble is that, instead of copying all the data from the row and putting it in the correct cells in the other datagridview, it seems to be taking the whole row object and putting it in the first cell, so the first cell contains this: [code]And the other rows are empty. How do I make rows copy properly?

how to print, and got it working pretty well. The text string I have printing into a rectangle, and if a word does not fit it will wrap down to the next line, and then keep going like that, but now I need to split my page into three different areas that will each print different text.I am pretty sure I could draw three different rectangels then draw the text I need on each of them, but is it possible to somehow merge them together into a single rectangle that will be printed?

I have divided the circle into rows and columns and each block(square) formed in the circle is of equal size. I have the X and Y co-ordinates of each square/block. Each block is either defined as good or bad.
Problem: I need to add 2 blocks on the same row and determine if the result is good or bad. If any of the block is bad, the group of two block is called as bad. If both are good, only then group is good. what would be the algorithm for it? I need to do in visual basic language. Also, I need to do more cases like adding 3 blocks and determine if the group of 3 block is good or bad. In this, if any block is bad, the whole group is bad.
Update: When I divided the circle into rows and columns i.e blocks, I remove the blocks that are not in the shape of square. That is, those square/blocks which are touching the circumference of circle are deleted. I can upload the photo tomorrow now.

I want to change the row color of every row in my DataGridView where a particular column value = "RBF3". I am currently using the DataBindingComplete event which seems to work fine, but it fires every time I change a cells value. I'd like for this bit of code to only fire when the datagridview is first displayed, sorted, or filtered. Is this possible?
