Copying Rows And Columns From One Datagridview To Another

Apr 23, 2012

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?

Highlight DataGridView Rows Based On A Columns Value?

Jan 27, 2012

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?

Copying Specific Columns From One Datatable To Another

Nov 25, 2011

This doesn't seem like something that should be confusing or difficult, but I'm having a hard time finding the answer to this problem. I want to copy columns with their data, not rows, from one large DataTable to a smaller one.I have a DataTable with many columns of data (around 20), and a string array of the columns (4 ) that I want in the copied DataTable. Is there a reasonable way to accomplish this task?

VS 2008 (DataGridView) :: Delete Successful Inserts Of Rows And Move Rows Up?

Jul 30, 2010

How would i delete only the successful inserted rows for insert and then move the non successful rows up and allow the user to correct the data and get it ready for an insert. If i dont delete the successful rows then i will have multiple inserts of the same dataRow and we dont want that! AND if i dont move the data up then it will have blank rows uptop and will end the try and not insert the corrected data. You can better see what logic i am trying to perform at the bottom of my code, right after I insert into the database. Here is my code.

Private Sub btnLaserGenerateTicket_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLaserGenerateTicket.Click

Print Rows And Columns?

Feb 14, 2010

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

Divided The Circle Into Rows And Columns And Each Block?

Jul 21, 2011

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.
