I have a DataGridView with 3 columns (metric_key, metric_name, metric_value).There are for example, 6 ROWS in this table (6 different metrics), added programmatically (DGV is not bound in any way)
Now, when I assign values in my grid I do:
dataGridView1.item("Metric_value",0).value = "value of the metric in row 0, in the column named "metric_Value".

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.
I have a form with some textboxes on it. The textboxes show values from a table. I have a binding navigator that lets you step through the records in the table and the textboxes update. What I want, is to have a control, say a listbox, that allows you to select a value which will filter the data behind the controls so that you only have one record.
So, for example, say you have a table of contacts. There are textboxes on your form that show name, phone, address etc. You could then have a listbox that showed a list of all the contacts and you could select one, which would in turn the textboxes. The filtering field could be contactID for example.
I have a datagridview with several columns, but what I�m trying to do is sum km2 column based on date. I�m using the following
Private Sub Form3_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.CadastroSeqTableAdapter.Fill(Me.Db01DataSet.CadastroSeq)
[Code]....
The query is grouping by DATE (data), this OK, but the km2_FF values not, is not showing anything. To be more clearer, this datagridview has different values of km2_FF for the same date, I want to display the total of km2_FF for each day.
I have an application i am working on which gets data and places it into a dataview.
One of the columns contains a url that shows an image of the item being listed, my question is is it possible to have a floating imagebox so that the image is displayed when i mouseover the url? this would be a bit like a preview the images are not large (64x100 say)
My initial thoughts on this would be to use a tooltip but can i use images from a url with a tooltip? if so how, if not how can it be done?
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...

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

I have a few classes, one is a form, the other is the source of the datagridview. I want to be able to sort the columns of the datagridview by clicking on the header. Here are the classes that I am dealing with:

Public Class ViewDiscoveryFlashCards
Private DBBindingSource As New BindingSource

I have a datagridview that's taking a while to load because my table contains almost 5000 records. How can I provide an easy way for clients to filter the grid based on a product name. I was thinking of having labels with each alphabet on my form and when they click a label it filters the bindingsource according to the chosen alphabet. this seems like an awkward solution though.
View 2 RepliesThere 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?
I have an untyped dataset which is programmatically bound to a form in vb.net 2008. The first record in the dataset is not necessarily the record the user selected to view. I need a way to, after the binding is done, move the dataset to that particular record. I have a currencymanger in play for use of displaying the current record of how many records. I think I need to do a search and find the row number of the select record and then use the CurrencyManager.postion to do this but have had no luck in 3 hours to locate anything I can use.

View 5 RepliesI am working on Datagridview. My task is adding buttons in the Datagridview table based on the case statements. Like In the Present table i have one column called "CategoryDescription". In this column, values are like 3101,3102, 3103........Here 31 is the common. and like 3201,3202,3203......Here 32 is the common. Like there are so many common values are there. So where ever the common values will come there i have to add one button in the Same column.

I have a list box that is bound to a datatable, which works fine. The question I have is this. I have a list of values in the form of a sqlDatareader that I want to use to select values in the list box, that is to say if the value from from the datareader matches the value member from the row in the listbox then select the row. I've come up with the following code, but can't find the syntax to utilize the SetSelected method.[code]...
View 5 RepliesIs there a way to manually select a row? Right now, it uses the default selection method where when you left click it highlights the row, but I would like it so when your right click on a row it also selects the row, because I would like that row to be active when the row is right clicked, and not just left clicked.

I have two datagridview's both are databound. First one shows items for sale and the second stores all the items that were sold. I am trying too transfer selected rows from one to the other but no matter what I keep getting told "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound."

I have bound an array of a class with 3 public strings.
When I run the form app and in the form load call I bind the array to the DGV all works fine and the DGV is fully populated. However, if I change an item in the array I had expected it to change in the DGV.. it doesn't. Or rather, it only updates if I click on the cell that should have changed.
I have a datagridview bound to a table adapter. It displays data just fine. Part of this data is a comments field. When a user wishes to edit this I open a seperate form with the data in a a text box. After the user edits this text, how do I update the database / datagridview?
I can update the datagridview cell's value but that doesn't propagate to the database until the focus is removed from the row. I tried BeginEdit and then EndEdit (which should commit) but apparently it needs to move to another row!
I have a form that contains a datagridview control that is bound to a dataset in design mode. This form contains various other textboxes and combobox controls as well and allows users to create and view Work Orders. It also has a Button control ("New W/O"), that when pressed will clear all values from all the controls on the form. My problem is that it's not removing the rows of data in the dgv.

How can I reset the dgv to retain it's default column headers but remove all the rows for the selected W/O?

View 1 RepliesOkay so I have a datagridview that is bound to a dataset. I have a column called type is a string char of either C, R, A, or V. The problem is that I want to sort the datagridview rows using that column and do so in the order I just gave so I want rows with C on top and then R and then A and then V. Because these aren't alphabetical, how could I sort the items this way? I did look into the icomparer, but really wasn't able to figure out how that works.

How can I do this in Linq. Unfortunately this app is coded in VB.NET as we inherited it that way.

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?
