I have a DataGridView containing a large number of columns. I want the users to be able to select multiple columns and then select a menu item to hide the selected columns. For example a user might selected columns 5 through 10 and I want the program to hide those columns. I know how to hide columns, one at a time. I can get the count of selected columns but I have not figured out how to get the index to the left-most selected column. Trial and error is such a slow process.
Considering the huge number of options offered by the DataGridView tool, it would be nice if this forum had a special category for the DataGridView (common to VB and C#).
Finally I got the desired results but it took a lot of coding, looping through the selected cells to find the one with the lowest column index, then a second loop to count previously-hidden columns, then a third loop for hiding the selected columns, stepping past previously-hidden columns and declining to hide frozen columns.
I'm hiding the "EmployeeID", my Primary key that is part of my datagridviews datasource. I need to get the value of that hidden column of the selected row of my datagridview. How do I go about doing that?
I'm trying to validate that a particular column in a datagridview has been selected.
I've created this code which transfers the value of the selected Customer ID cell in the datagridview to another form.
Private Sub mnuFileEdit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnuFileEdit.Click 'Define variable for the current selected cell value
It's working fine but at the moment any column in the datagridview can be selected and transferred which causes an error.
So I want to create an If Then statement which confirms that the selected column with the dgv is the PK_ID (customer ID) column before processing the rest of the code. I've tried playing around with "If dgvCustomerSearch.SelectedColumns("PK_ID") Then" but a "Value of type...cannot be converted to Integer" error occurs.
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?
I can't seem to set the selected index or selected value of a DataGridView combobox when loading data from a database. My DGV has two combobox columns which are bound to datatables. The DGV itself is not bound initially. After adding a row, I select a value from each combobox which then populates the rest of the cells in the row. I'm using the EditingControlShowing event to add an eventhandler to catch the SelectedIndexChange of the combo boxes. This all works as needed. My issue comes when populating the DGV with saved data, I need to add the rows and set the selected index and/or selected value of each combo box. I've searched through various forums and articles for the last week with no luck.
I'm using VS2008 sp1, .NET 3.5 sp1 and SQL 2005 sp2 Express.
I am using vb.net 2010 and winforms and DataGridView. The DataGridView has a DataGridViewComboBox column. When I show the form with the DGV it shows this and empty grid but the column that contains the ComboBox shows the first item on the dropdown list. How can I have the ComboBox display nothing until it is clicked on and selected?
how do i get the selectedindex/item of a datagridview combobox column?what i want to do is change the back color of datagridcombobox when something is selected from the combobox?So, selecting 'false' will change the color to RED and selecting 'true' changes the color to GREEN.
I am using vb.net and winforms.I have a Form with a Bound DataGridView. On the DGV I have 5 columns with ComboBox. I am using the Editing Control Showing Even to catch the ComboBox Selection. (see code bellow).Here is the problem: After I click on a Cell with a ComboBox and make a Selection and then update the underlying cell (cell = selected value) and then click on another Row of the DGV it goes haywire. If after I update the Cell I do and EndEdit on the corresponding row of the DataSource it seems to work find.How can I determine whe corresponding Data Source row so that I can automate this? [code]
I have a Data Grid View and some of the columns are of type ComboBox. What happends is that when I click on a cell that's a ComboBox it Selects the ComboBox but I have to click it again for it dropdown and show the Combox Items
I have a datagridview containing 1st column (combobox), 2nd and 3rd column is textbox. The combobox was filled-up using datatable. My problem is on loading form, I will get a records from my database and set the value of my combobox base on those records. So if I have 5 records from my database then I should have 5 rows containing combobox in my datagridview.
I tried the code below but there's an error saying "the following exception occured in the datagridview...." but it will display correctly, but if I click in any cell that error always appear.
Private Sub frmEditIngredientManagement_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
I have a datagridveiw combo box with a few values in there. I am trying to capture what user clicked. I tried CellValueChanged, CellContentClicked etc. but nothing works. I want to store this value to a variable (important) and then shift the cursor to Column after user has selected value.
in order to create my own type of columns. USERNAME to have type ComboBox NAME to be type normal like it comes from dataset But I don't know how to create a a column that is combobox and another one that is normal like it comes from dataset.
actually i have 3 fields in database which are Sid Fee status what i want to add combo column in field [status] with two option PAID or UNPAID which a user can select and update it .i am all clear with filling the datagridview from database and updating but only problem is adding a combobox in third field that is status.

I have a string field, EventAction, that is in the database.I want that column to be a combobox column.I want to add the different EventActions to the list and let the user select the action they desire.
I have a Form and I have a DataGridView in this Form. My DataGridView does have a Combobox Column, when I am trying to Databind this DataGridView into my Datatable, it gives me an error: DataGridViewCombobox Cell Value is not valid. I have read all other examples , but I did not get anything because I am new at it.
I have an unbound DataGridView control that displays a few columns of account data. The first column is a combobox that I fill with data from a dataset of names filtered by what's in a customer field on the form. When you click on a combo on one of the populated rows, the available names come up in the combo. But if the first click in the datagridview is on a new row's combo, various (incorrect) names appear. Only after you click on one of the populated row's comboboxes, does the correct data appear in the new row's combobox control.
I don't really understand why this is happening. I have been using the EditingControlShowing event to populate and add the combo to the new row, but it doesn't seem to be working very well. I hope someone out there has some ideas about the correct way to do this.
I have a qestin of how to access the ValueMember after setting it? A useer adds values to a row on a grid and selects a value from the combobox. Now I need to roll through the rows to validate and insertt the records into the database. I cant seem to access the ValueMember property. I have set a a looping structure and want to access the ValueMemeber property. I can get a property called Value, but it seems to be the DesplayMember value. How to access the Valuemember?
I've got a window with multiple datagridviews. Each with data from a separate dataTable. All of which are part of the same DataSet. There are a couple of places where one DataTable has a field joined with the lookup dataTable from the dataset. For example a lookup table for LugSizes has a field called LugSize that is also it's primary key. Another table called Device Terminations has a field called LugSize to which the user can only select those values from the LugSize lookup table. I thought it would be as simple as using the Items.Add method for the combobox column whenever a new lookup table row was added to its own datagridview. Unfortunately, when I try to initially clear the items list, the data error event is triggered for every row.
Here's a sample of my code if it helps:
Private Sub FillLugSizeComboBox() Try If colDTLugSize.Items.Count > 0 Then colDTLugSize.Items.Clear()
I have a datagridview which has mixed values in one column. Is there a way to add a control into the Value cell depending on the row? For example, for Name and Age row, it will be a regulator textbox but for the Products row, I want to be able to add a combobox.
