Databinded Datagridviewcombobox Column Not Showing Anything In VB 2010?
Jun 8, 2012I migrated a project from VB 2005 to VB 2010. I have a datagridview binded to a dataset populated by the MySql Connector. One of the columns, with integer values, is displayed in a datagridviewcombobox type column. In VB 2005 it worked perfectly. But now, once migrated to VB 2010, the column doesn´t show anything. If I change the type a a textboxcolumn type, it does show the data. The column in the dataset is Integer, and the column in the datagridview is Integer also. But, strangely, although the value of the cell (when debugging) is Integer 1, the formatted value is String "" (empty). If I add integer items to the combo manually, the formatted value is the first added item, but still string, and not equal to the value property. It is the same whether the column is designed and added programatically or visually with the editor of the datagridview. It seems a bug in the combobox type.

Oct 7, 2011I am using a datareader to pull data from my database. I store the data in a multidimensional array in a seperate class file. I access the values in the array from a form through properties.The problem I am having is when I run the project as I step through the code I can see the values being added to the array but when access it from a string property it shows up as string System.String[,]. I would like to have my array transposed accross the listview under the corresponding column. below is the code I am using.

DataGridViewComboBox Seems To Be In The Way
Jul 25, 2010The code below works as it is now. It creates a datagridview with a combobox on it. The combobox updates a common field called personid.
My problem is I need to add a new column to the left of the combobox. If I just add this field to the sql (right after "SELECT") for the dgv it doesn't work. It does work if I put it after the combo but I need to have this column to the left of the combo.
How do I go about doing this? The dgv is created entirely in code and this cannot be changed.

Which Event To Use For DataGridViewComboBox
May 16, 2012I have a DataGridView that has a column defined as a ComboBox. When I select a value from this ComboBox, I'm not sure which Event I need to check. Ultimately, I need to read a DB Table to retrieve data based on the value selected from the ComboBox.
View 2 RepliesAdding To DataGridViewComboBox During RunTime?
Mar 23, 2011I have added a DataGridViewComboBox to my DataGridView during design time. It has 0 items in it and I need to add a bunch of items to it during runtime.
In most controls, they have some kind of direct method like ".Items.Add("etc")", but for the life of me, I can't figure out how to access the DataGridViewColumn programmatically.
I can create a new ComboBox during runtime and add it to the DataGridView, but that's not what I need to do.
I played around with IntelliSense, I've searched on Google and I've looked through the documentation. The only thing I could find on MSDN was DataGridViewControlCollection, but I didn't see anything that would allow me to directly access that control.

View 8 RepliesIDE :: Datagridviewcombobox Closes Immediately
Jan 13, 2011I have an issue with VS 2008 datagridview combobox control.
The combo box in question closes immediately after the CellValidation method that I wrote invalidates the input in the combo box cell. What I mean by closes immediately is that when the drop down arrow is left-clicked, once I remove my finger from the left clicking of the mouse instead of staying down so that the user can see the selection options the combo box just closes.
I'm currently using EditOnEnter as my EditMode style. (I've tried switching between the different option the same behavior exists). The datagridview is bound to a dataset which was created from my database in MS Sql Server 2005.
This problem exists on two different forms and occurs exactly the same way. I don't know what other settings to mention to help in the troubleshooting of this error, but please feel free to ask me any questions so that I may resolve this issue. By the way both forms use datagridviews tied to the same dataset, just different tables and table adapters.
Set Datagridviewcombobox Value Based On Valuemember?
Aug 24, 2011box withing a modal form. The combobox shows a list of ingredients where the displaymember is the IngredientName and the valuemember is the IngredientID, and a user would select an ingredient in the combobox and the returning value would be the ID for that ingredient. My issue is that within this same datagridview, i'd like to prepopulate it with items already existing in the database. However i'd like to set the display value in the combobox using the id value from the database. So if "Pasta" was the ingredient name and 101 was the ID, i'd set the value as 101 and it display Pasta in the combobox.
Here's what i have so far:

Example Diffrent Color For A Specific Value In A Datagridviewcombobox Column
Dec 23, 2010I wanted to visualize to the user the diffrence if they opted for certain values. In mycase certain choises would show phonenumbers on intranet.To show how I wil leave the control names default. To recreate the the project. Start a windows form application, place a datagridview, and 2 bindingsources on the form To start we need some data to show and a list to choose from.To make a simple example I chosen to make a person class containing an Id, Name and Position.Id If the Position is a staff position it should be blue others should remain the default style.But lets start with the colorScheme Interface so we can store the colorscheme we want to show for a certain positionitem in the datagrdview It wil need back and forecolors but also colors for teh item whilst selected. To show the Displaymember we want to see I've also added the toString property that should shadow the toString of the object.[code]
View 2 RepliesIDE :: Cannot Exit Form After Updating DataGridViewComboBox Cell
Oct 22, 2010The form opens a simple form to accept a password if a name is selected from a dropdown. The form is opened modally from the validating event. If I select an item, fill in the password, close the modal form , it will not let the parent form close depending on how I exit the dropdown. When I look at the closing event cancel is set to true implying that the control still thinks it needs vaidating.
It works if i leave the dropdown cell in focus when I hit close.
If I click (even just once so the dropdown still is highlighted but just closed) on another cell in the grid the form will not close. It corrects itself if I repeats the first method.
Even worse if I press enter twice it crashes without going through any of my code when the grid tries to do its own commit edit on the editableControl but seems to have a wrong reference as it tries to use the DataGridViewComboBox as the editablecontrol and gets a cannot cast exception
Updated as I have found the cause.
The pop up password form is a home brewed modal form by disabling all open forms but leaves some menu items active.(mdi is used). It is the disable form that causes the issue. Without that it always works. So it seems the grid cant handle being disabled while changing cells.
A solution that works is to use ShowDialog but that changes the systems behaviour so I may not be allowed to do that.
.Net 2008 : Multicolumn Combobox Like Access?
Jul 17, 2009I am running VS2008 and developing a Windows Form App in VB.Net. Is there not a bound multicolumn combobox like Access has had forever? If there is one buried in VS2008, the Windows OS or MPF 2010 or somewhere else would you mind sharing? I could hardly believe my eyes when I did not see one in the common controls list.
Not knowing the correct terminology, I would like this control to be a tool component that I can drag onto my form and set the binding and column properties and be done with it.Come on Microsoft VB.Net Dev Team... where have you been on this? This type of control has been out for umpteen years in Access and 3rd party took kits. There is nothing that says Rapid development like roll your own code! I have seen serveral articles on how it can coded;?

View 2 RepliesVS 2005 Displaying Multicolumn Data - Which Control?
Jul 17, 2009I would like to create a multicolumn list of items, similar to the right pane of the Windows Explorer window. There are rows, one for each item.

(I mean, no database, no spreadsheet is available as a source.)
