Hide Buttons In Select Rows With ButtonColumn In DataGridView?

May 6, 2009

Is it possible to add a button column to a datagridview and then remove a select group of these from rows without removing the rows themselves? That is, I want the ability to hide or remove these buttons in certain rows after certain actions have occured. I realized that I could simply delete the rows with these buttons, but I want to keep the data in these rows visible without the user thinking they have to use the buttons. I am assuming that I can also disable the buton in the desired rows as well.

Mar 11, 2010

I need to select multiple random rows in DatagridView with keypress.Ex:

Row1 -selected
Row2 -not selected
Row3 - selected

I do have part of code that will update certain field in database on keypress, but i have no idea how to create multiple selection and display it on DataGrid.CTRL+Click is nice, but I would like to have option of selecting rows with keypress.In following code I am checking if certain field is marked for selection(i want to give user an option to start selection, exit program then continue selection later) but it allways select all rows in table (even if only one is marked).

Dim NumRow As Integer
NumRow = 0
Do Until NumRow = dbtShow.RowCount - 1

[code]....

My question is: What is the best way to select multiple random rows in code?

Datagridview:need It To Grow And Shrink Depending On The Number Of Rows?

Sep 22, 2011

I have a datagridview created for my windows app in 2005 and I'm not sure how to get it to grow and shrink, depending on the number of rows that are displayed. The form contains several filters for the user to use in order to get their desired recordset displayed in the grid and therefore, the size of the grid will be constantly changing. How is this usually handled?

C# - Limit Number Of Rows That Can Be Entered In A Datagridview Based On Property Of DGV?

Feb 24, 2010

I have a UI that uses datagridviews / bindingsource / datatables of typed dataset for data entry. The dataset itself is serialized to a varbinary(max) in SQL. (i.e. no tableadapter, backend schema).I would like to limit the number of rows the user can enter into some of the grids (the data is used to fill PDF forms and I don't want them entering more rows than the forms can accomodate.).I have subclassed the datagridview, added a rowlimit property and tried to manipulate the AllUsertoAddRows property

Imports System.Windows.Forms
Public Class dgv
Inherits System.Windows.Forms.DataGridView[code]......

The behavior I see is that the messagebox comes up after leaving the max row even when the user is trying to leave the grid. I can lose the messagebox and deal with notification some other way but I thought someone else may have come up with something a little more sophisticated to handle simply causing attempting to add to many records to navigate out of the grid to the next UI control.

Forms :: User To Be Able To Select Any Number Of Those Checkboxes/rows And Then Return A Value To The Table "stamping" That Users ID?

Jan 8, 2010

I'm working on a project and my boss insists I use a DataGrid for this. The grid holds information for work orders, one of the cols has a check box in it. I need the user to be able to select any number of those checkboxes/rows and then return a value to the table "stamping" that users ID. This is what I have so far to get the grids populated... I'm using 2005 with a 2000 Access Database if that helps. Though this will be changed to SQL Server once we get it working (yay more work)...

[code]...

I removed the code from the second grid to make it easier to read, obviously once I can get one to work the second shouldn't be as much trouble.
This is the check box: dgvNewBiz.Columns(1).HeaderText = "Select"At this point if someone knows how to get it to recognize the click event of the check box and pass that row info to a variable that would be super as I'm sure I could probably figure it out from there.

VS 2008 (DataGridView) :: Delete Successful Inserts Of Rows And Move Rows Up?

Jul 30, 2010

How would i delete only the successful inserted rows for insert and then move the non successful rows up and allow the user to correct the data and get it ready for an insert. If i dont delete the successful rows then i will have multiple inserts of the same dataRow and we dont want that! AND if i dont move the data up then it will have blank rows uptop and will end the try and not insert the corrected data. You can better see what logic i am trying to perform at the bottom of my code, right after I insert into the database. Here is my code.

Private Sub btnLaserGenerateTicket_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLaserGenerateTicket.Click

Can anyone tell me why "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound." I keep getting an error "Invalid Operation Exception was Unhandled" error. All I am attempting to do is allow the user to select products from a list(or a second datagridview) and have it added to the datagridview so they do not have to type in every cell since the other cells are not visible because they do not purtain to their needs. Plus they will be able to save all items at the same time.

Save Datagridview Rows As New Rows?

Apr 26, 2012

It was even difficult coming up with a Question title for this.

Am not sure whether am using the right approach to my problem. See i have this datagridview that contains rows that i would like have saved back into the Database as new rows but with a column altered to a new value.

Eg

PKColumn1 FKColumn2
Column3 Column4
1 1

[Code].....

What am looking at is Change FKColumn2 (some foreign key, maybe i can also have a combo box somewhere on the form and an "import to") values to something like 2 and save the rows back to the database without loosing the original rows.

DataGridView - Nonvisible Rows Are Still Visible And The DataGridView Is Empty Despite Having A DataSource

Jul 30, 2009

I have several problems with rows in a DataGridView. Background information: The DataGridView (DataGridViewCalib) is in one TabPage of a TabControl, some columns of the DataGridView are automatically DataGridViewCheckBoxColumn as the DataSource have some colums which are Boolean. This is a Windows Form written in VB.Net with Visual Studio 2008. The user loads an input data file.

The problems:

1) At first arrival in the TabPage, ShowDataGridViewCalib (code below) is called. All rows are then shown in the DataGridView, despite the code saying that some rows should not be visible. Breakpoints in the code show that the code do arrive at the Rows.Visible = False events. Despite all rows beeing shown a Watch in the debugger shows that:

[code]...

There are two alternative ways of handling the rows in the code. The first attempt (commented away here) is probably the "nicest".
