Control Datagridview Selected Row Color And Selected Cell Color?

Jan 16, 2010

I want to have my current row stand out as the current row by virtue of the background color.I also want my current cell stand out from the row color.

in other words i want to controll the background of the current cell as well as the current row, and have these colors different from each other as wel as the background from the non current cells.

I am getting confused with the notion of the current row vs the selected row.I have tried messing with the default row style.selectedbackgroungcolor as well as the same for the default cell style, but cant get it to work the way i want.

i can almost get it if i set the selection mode to full row, but then cannot get the current cell to have a different background color.

Checking Treeview Nodes - If Parent Is Checked Check All Child Nodes

Aug 31, 2011

I'm all new to this treeview business. I have a fixed treeview, very simple and basic. Only two levels, parent and child nodes. I just need two things out of this treeview.

1) If parent is checked, check all child nodes.

2) If just one child node is unchecked, uncheck parent node.

That's it! I've been looking for this for 30 mins and I cant find it. Maybe because my vb.net is old, it doesnt seem to be the same as others =/ I'm using vb.net 2003.

Loop Through Treeview Nodes To Delete Certain Nodes?

Dec 16, 2010

I call the sub as follows:

Datagridview Selected Row Color Change ?

Jan 2, 2011

I have a datagridview with the rows color coded for specific values...To make it easy on the user, i want to do what I did in vb6, something like

MSHFlexGrid1.BackColorSel = MSHFlexGrid1.CellForeColor

MSHFlexGrid1.ForeColorSel = MSHFlexGrid1.CellBackColor

basically, when a user selects a row... the colors should inverse. for instance, if the background color is red and the foregrould is black when the user selects the row, the foreground becomes red and the background black... and then goes back to its orginal color when the user leaves the row.

Change Either Selected Tab Font (to Bold) Or Color?

Jul 18, 2010

I've been googling, testing, etc for a couple hours and I'm right where I started off. the vb.net tab control sucks... Does anyone have an tips or code to make it so when I select a tab the font color changes OR it just makes the tab heading text bold?I've messed around with the draw commands and while that does work, it draws the borders/backgrounds so they are very old / outdated looking.This is basically for a simple tab text editor I'm working on when a textbox in the control changes I can update the associated tab with either a red font or just bold it to indicate the textbox on that tab is modified. I've definitely be open for alternative tab controls as long as they are free and come with a vb.net example :)

This is in vb.net 2008 express
