Setting Values On DataGridView From Context Menu
Jun 5, 2010I'm have an app that currently allows a user to select a color (from a Color Dialog) which updates an unbound Datagridview with the name of the selected color & also changes the background of the selected row to that color.
I need to do one of 2 things:
Either change the Color Dialog so that I can set the colors available
Or Allow the user to select colors from a context menu and have that update the Datagridview.

Insert A New Right Click Context Menu Item To The Existing Right Click Context Menu For The Active Window?
May 15, 2010VB express 2008 .net 3.5 or .net 4.0 VB express 2010?I have written application to convert RTF to HTML. The main Purpose of the application is to copy VS code to the clipboard and covert it then put it back into the clipboard as a HTML Document so that it can be pasted into a HTML document such as Windows Live Mail. I found that code copied and pasted is spaced out in in the wrong positions.
The applications works perfect with no bugs so far. I then asked Myself how to go about doing the copy with the least amount of operator interaction. So I added an Icon to the Icon Tray with a right click menu to use to convert once the Rich Text Format was copied to the clipboard. This works fine except you have Five steps, Select the text, Copy to clipboard, Right Click the icon, Select the Converter and Paste. The normal is three steps.
To this the best solution is to add a context menu item to the active form such as the RTF editor or window. So that when you select the Rich Text to copy and right click on the form to bring up that menu then to Just Select the menu Item such as "Copy RT and Convert" I searched and found about 544000 Items and tried to restrict down to no avail. I read until I finally gave up. I did not find any code examples of this. Almost every thing I found related to the web or some other explicit document like Excel and not to the Various windows that could be active with RT in it.
how do you add a context menu item to the context menu of an active rich text format window such as WordPad or VB?I have test in my application that tests to see if it is a RTF in the clipboard so if it is not the converter does nothing.

DataGridView ComboBoxColumn List?
Jul 12, 2009I am populating a DataGridView from a DataTable with a DataAdapter (VB 2008 Express, SQL 2008 Express). The dgv is for editing (with SqlCommandBuilder) a SQL table. I have added a ComboBoxColumn ("Type"), with a list, and removed the column from dgv ("Reason") who's index it replaces. What I can't figure out is the binding(?) to have the selected text displayed the same value as that from SQL table that is being edited. The ComboBox displays an index of -1, I need the selected text to be the data from row and field which is to be edited. The list is constant. Code so far is below:

Datagridview With Manually Added Comboboxcolumn?
Jan 14, 2011i am using a Datagridview on my form. It get's it's datasource from a dataset: grd.datasource=set_temp After that I add ComboboxColumns manually. At the end I loop columns and set values into that cells from the comboboxcolumns. Works perfect so far. Now I click on a header and the sorting is changed, and then the cells from the comboboxcolumns all lose their values, they are all empty.
Why and what do I do to avoid that? Or must i refill those manual Values after sorting?
VS 2010 : DataGridView ComboBoxColumn In MDI Application?

View 3 Replies.net - Binding A Collection Of Objects To A ComboboxColumn In A DataGridView?
Jan 24, 2012I have a GUI which allows the user to select a report to view/edit. When the user selects a report, it shows the Items in the report. The Item has many properties - most of which are binding properly. One of the properties is Owner, and this is bound to a ComboBoxColumn.
Report
Items
Owner
I have done something very similar to this a few times and had no problems when I set the DataPropertyName, DataSource, ValueMember, and DisplayMember. The only difference is that this time instead of the Item type having an OwnderID it actually has an instance of the Owner object.giving the items bound in the list a self-referencing property that allows them to return themselves for the purposes of setting the ValueMember.However, When I bind it this way:
OwnerColumn.DataPropertyName = "Owner"
OwnerColumn.DataSource = ownersBindingSource1
OwnerColumn.ValueMember = "Self"
OwnerColumn.DisplayMember = "OwnerName"
I get a lot of errors like: Unable to cast object of type 'System.String' to type 'Owner'.
and:
The following exception occurred in the DataGridView:
System.ArgumentException: DataGridViewComboBoxCell value is not valid.To replace this default dialog please handle the DataError event.I was able to get around some of these errors by binding it like this:
OwnerColumn.DataPropertyName = "Owner"
OwnerColumn.DataSource = ownersBindingSource1
and also by making the ToString function on the Owner display the OwnerName property. This seems pretty hacky though - and I think I'm misunderstanding something fundamental as it still does not function properly.
Selecting Child Object From ComboBoxColumn In DataGridView?
Sep 22, 2010With the two lists (t1s and t2s), I want to display t1s in a DataGridView, and in one column show the T2 property as a comboBox column, which dropdown will show the t2s list such that a new list instance can be selected. T2 has a Name property that should be used for displaying it in the comboBoxColumn.
I'm able to display the dropdown, but remaining a few problems:
1. How to display the correct comboBox "selection" on "load"?
2. How to change the T2 child object instance when combobox selection is made?
3. This is a really basic problem, which suddenly happened and I just couldn't understand what I have changed; The code marked BLUE now just shows empty cells.. While the AutoGenerated columns do show values.. Shouldn't those "manual" columns work?

View 2 RepliesComboboxcolumn In DataGridView With An Event That Autosizes Cell Width
Nov 25, 2009I have a comboboxcolumn in a DataGridView. I have loaded int with string data that appears in the dropdown box. I have added an event to it for an SelectedIndexChanged. What I am trying to do is autosize the width of the cell in the column based on the string chosen in the drop-down box within this SelectedIndexChanged event. This seems to work but it does not work off the initial selection change. When I select the desired string in the dropdown box the width of the cell does not autosize. I am not sure why.
I was trying to get around this by wrapping an IF stmt around the autosize logic by saying if cell value = "" then cell.width = Max Width of all loaded strings/ However, I can't figure out how to access the string array loaded into the dropdown list

Datagridview With ComboBoxColumn Fetching Data From Joined Table
Dec 16, 2009I am using VB 2005 professional and SQL Server 2005 express edition.
For the last two weeks I have been trying to have a datagridview control on a form that will have datasource from a dataset with two tables that are related. I want child the column to be a ComboBoxColumn where userts can select options and update the other data(from the other table).
I have two tables in an sql server 2005 database named computers:-
computers
locations
Table computers looks like thisID is the primary key column)
ID Location
Computer139
Computer240
[Code].....
With the location column being a ComboBoxColumn so that when a user enters a new ID say Computer5,they have a choice of a dropdownmenu for the Location column. In the database table computers the item should be saved as well as the index value(to correspond to the LocationID).
Load The Data From Database Into A Datagridview With One Of The Columns Being A Comboboxcolumn?
Jul 27, 2010easy way to simply load the data from database into a datagridview with one of the columns being a comboboxcolumn. Apparently there is no selectedvalue, selectedindex or value as in a combobox to return the combobox value. What I need is to verify if the database value is 'true' and if it is then I need to set the comboboxcolumn with a specific value.
Ex:
if ds.tables(0).rows(0)("flag") = "true" then
datagridcolumn.selectedvalue = 1
else
datagridcolumn.selectedvalue = 0
end if
VS 2008 Get Datagridview Comboboxcolumn Value Moment A New Selection Is Clicked
Nov 27, 2009I'm pretty new to VB.Net programming, but have already been able to figure out many things using this forum, but also via the many other forums on the internet.I'm currently stuck with a question though regarding getting the clicked value in a datagridview comboboxcolumn.When I use _Selected IndexChanged and then check the current cells value, what I get is the value before I clicked the new one in the comboboxcolumn.When I use _CellEditFinished, I can get the new value, but only after I selected another cell, or changed focus to another object.How do I get the new value from a DataGridViews ComboBoxColumn the moment I clicked it in the pulldown menu from the ComboBoxColumn?
