Adding Combobox To Bound Datagridview

Jun 2, 2011

Has anyone here tried putting a combobox to a bound datagridview? The selected value of the combobox will depend on the value of the corresponding column in the database.

I have a datagridview. When the user clicks the edit button, the application fetches the records from the database and binds it to the datagriview. But I want to show the Gender Column as combobox with selectable 'Male' and 'Female' values.

How could I add a combobox to bound datagridview?

Read Combobox Selected Value From Datagridview Instead Of Bound Value?

Oct 1, 2011

I'm loopiing through a datagridview and I want to get the selected value in a combobox, not the bound column's value. (I'm putting the contents of the dgv on a Word document.)

For icounter = 0 To Me.ConversationTblDataGridView.RowCount - 1
range.Text = range.Text & Me.ConversationTblDataGridView.Rows(icounter).Cells("PersonID").Value <-- I want to change "Value" so I get the displayed value, not the person's id
range.Text = range.Text & CHR(13)
Next icounter

It will not take .DisplayMember or .SelectedItem and .Selected returns True of False. Can anyone tell me how to get the name that shows in the combo box instead of the id number?

DB/Reporting :: Displaying DataGridView Text Column In A Mixed Bound/Unbound DataGridView?

Mar 15, 2011

I have a DataGridView (dgv) on a Windows form (VB.NET) which is bound to a datatable. One of the bound columns is a an ID (Foreign Key) to another datatable. All I want to do is Hide the ID column and populate an unbound column with the Name (ParmName) for the user. I searched the foreign value in the datatable and retrieved the information. I set the Value of the cell in the Datarow. All works well, but does not display. The cell accepts the value...I can even Debug.Print the values to the console. They are there just nothing displaying in DataGridView. Nothing odd about DataGridView. Should be straight forward...

My Code
,
Dim dtParm As DataTable = MyDataSet.tblParameter
Dim dgv As DataGridView = Me.dgvResultNum_DataGrid

Bound Datagridview Not Bound?

Jul 9, 2010

There is something strange going on with my datagridview.

I've a data adapter that fills the underlying data table from a database. Then I assign this datatable as datasource to the datagridview Then I add a row to the datagridview and immediately I need to update the table in my database (as soon as user leaves the newly created row).

At this moment I have more rows (+2, not +1) in my datagridview than in the underlying datatable (the new row doesn't exists yet in it so the data adapter .Update method doesn't write anything to the database).

When DataGridView's .RowLeave event fires the undelying datatable is not yet updated. I've a question - is this behavior normal?

Jan 5, 2012

I bind a datatable to the combobox.DataSource on load. I then give the combobox aisplayMember and a ValueMember (2 different columns out of the datatable). In the SelectedIndexChanged of the combobox I would like to use the SelectedValue property of the combobox, just to test I MsgBox(combobox.SelectedValue) and I get "Argument 'Prompt' cannot be converted to type 'String'." Why isn't it displaying the value?

Set Bound Combobox Based On Value Of ValueMember?

Jan 25, 2010

I am using a bound combobox control in a vb.net application. How do I set the combo box to an item if I know the value of the ValueMember, but I don't know the DisplayMember. I can use the FindExactString method if I know the DisplayMember, but not if I only know the ValueMember.In explanation, the value member is an employee Number, the display member is the Name. I get the employee number from a detail item in another table and now I want to set the combobox to display the Name that goes with that detail item.
Can someone post some vb code to show how to do this.

Combobox Taking Values From Another Table Than That To Which It Is Bound?

Mar 18, 2010

I have looked all over the web for a way to set up a VB 2008 combobox but what I have seen makes me shudder! I want to , as In Access VBA, set the recordsource/datasource for the combobox i.e. the list shown in the combobox, to the values of another table (currency) and then when the user selects one of these values to store it in the (already) bound field of the combobox (to another table). In Access of course there was a wizard for this sort of thing, but in VB 2008 looks like it is just lots of code.

ToolStrip ComboBox Using Data Bound Item?

May 4, 2009

I have created a search/query facility after watching one of Beth Messi's videos. I notice that we can convert the textboxes on the auto generated search toolstrip to buttons, comboxes, etc. So, when we wanna search for a data in the datagridview, we enter a keyword. I wonder if it is possible to change the textboxes to comboboxes and make it bind to the datasources, so that users can use the drop down, instead of typing?

Validating And Storing Selections From A Dataset Bound Combobox

Oct 20, 2009

I have a combobox that is bound to a dataset. The dataset has 3 columns of data. at any given time there could NOT be any data in the dataset.

When someone selects an item from the box I want to store data from 2 of the columns of the row they selected.I do the 'store' in the selectedindexchanged event.

so currently I am assigning each column/row value to a property from a datarowview i get from combobox.selecteditem.

Code:dim column1 = drv.row.item(0).tostringdim column2 = drv.row.item(1).tostring

But I am getting NullReference exceptions all over the place when there is not data.So i have to wrap it all in a try catch and assign nothing to the properties when the Null exception fires.

I want to also validate that there is a selection made. There must be a selection made if there is no data in the DS fill it.I do this in the combobox validate event.

It just seems like there is a better way to check for no data coming from the combobox.

I wish there was a way to do some sort of .count on the datarowview you get back from the combobox.selecteditem but anything i have found also gives a null ref exception if used.

Also what is used to programmaticly change the selected item?

VS 2008 Changing Bound Data When Entering Text In ComboBox?

Aug 9, 2009

I have a data-bound combobox that pulls values from a BindingList(of T). Combobox loads fine, correct values are displayed (I'm not using SelectedItem or SelectedValue). I'm using properties and connecting the data to the control via a bindingsource.

What I want is if the user types text into the combobox, I want the data from the bound table to change to that new text, i.e. edit the bound data directly.

Easy as pie to do with a textbox, but can't seem to get a combobox to work this way.

I was trying to use the validated event of the combobox to write the data to the datasource, but it doesn't fire when I press enter. Is that the way to do it? Can I not link the data to the combobox directly?
