I have a datagrid view that loads data from a database. This is unbound datagridview.The columns are Description, UPrice, Quantity and TotalDescription UPrice come from database then quantity is typed. I want it so that when my datagrid loads, cursor goes to Quantity column and it is shown blinking like we have in text boxes.
I have a data grid view with columns created when it was filled from a sql table. some of the data types are "bit" (meaning 0 or 1 and automatically shows a check box in the column of in the data grid view).I need to get a handle of the cell that has a check box in it so that when a check box in one column is checked or unchecked, i can change the status of the rest of the columns (only one column can be checked at a time) and then update the entire row in the sql server..when column 3 in the data grid view is checked, app will uncheck column 2,4,5 run sql statement to update changes?
I have the following code that checks if the value in a cell contains a nummeric value.
Private Sub dgvOrderRegel_CellValidating(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellValidatingEventArgs) Handles dgvOrderRegel.CellValidating Select Case e.ColumnIndex Case 4 'Aantal If Not IsNumeric(e.FormattedValue) Then
IF cursor leaves column 0 and row 0 then it displays msgbox but I want to check where column 0 and row 0 has value or empty In case of empty cell it must display msg as msgbox("this is empty cell")
I have a desktop application by which i have to send mail to multiple recipients. There is a grid view in a form. There are some customer list in the grid view and for each row there will be a check box. User can check or uncheck the check boxes. Also there is a send button. when user click on the send button then a mail will be sent to those customer whose check boxes are checked.
I have gridview with checkboxes. I need user to click row in the gridview, then popup the 2nd window which contains the values of clicked row. I can propagate string values, but not the status of check boxes. code is like this UpdateForm.chkboxincomplete.CheckState = dgridview1.Rows(e.RowIndex).Cells(3).xxxxxxxxxx i need to know what to put for xxxxxxx or any other method to do this task.
i m using these code for selecting data grid row [code]but , when no of row more then grid showing rows then grid not show selected row in grid screen, for showing selected row we have to use scroll bar, my problem is how to show selected row in grid automatically
I am almost there but for some reason I don't find the answer to my issue. Here it goes. In my application I have a form which displays a data grid view with some info I get through XML from a web server. The data grid view have as first column a Check Box colum. The second column have the information I get into a variable (from cells), one by one, to pass it to the sub with the XML command.
What I want to do is to be able to select all the rows and send the cell info of the second row (only for the selected rows) to my sub which will execute once then send the second cell info and execute the sub and so on until all the loop is complete. Currently my code works only if I delete one row at a time (sending the XML code will delete the info in the web server and update the datagridview which in return will remove the item).
I want to bind two dynamic column's check box in one grid view like category column have some types and sub category have some types.. I should bind that two fields dynamic check box's with in a one grid view..how to do it.
I have an insert statement which works fine but before the record is saved I want to validate the text boxes. So I just need to know how to check for empty text boxes before the save button is clicked on. I have seen a couple of examples like:
Dim ctr As TextBox If ctr.Text = vbNullString Then MsgBox("empty box")
I'm able to validate the cells if they are empty but I'm not able to check the length of the cell. I want the user to enter 5 digits and if it is less than 5, show up a message box. [code]...
I have data grid view with checkbox as unbound column and a button at the bottom and when button is clicked i want to check all rows in the datagrid view i.e check the checkbox if it is not checked for all rows in datagridview. If button is clicked again i want to uncheck the checkbox for all rows if the check box is checked.
I have students who will be enrolled into a course. The student grid view has many columns like client_no, student_name, date_of_birth, address, etc. There are over 100000 students so I will need to filter the student grid view to find the correct student to enroll in the course. Once they are found, the user selects them and somehow moves them to the enrolled grid view. If a student drops out then they would be removed from the enrolled grid view.This process needs to be easy to understand and use. Are there any examples available or other suggestions on how to do this?
The problem is that if you never enter anything into a cell for a new row then that cell is never validated. This is a problem because I have columns that should not be null. I am doing the check in the row level validation and storing the information about which cells are empty that should not be empty. The row level validation works fine and the row level validation error indicator goes on,(red exclamation mark at the beginning of the row) but I also need a visual indicator on the individual cells that are in error.
I am thinking that setting the HasError property for the cells that are in error should cause them to display n error style (the default red border). Is there a way to this this either from XAML (perferably) or from code?Alternatively I could cause those cells to re-validate when the row editing is finished. Does anyone know how to do this?
I have a datagrid that will be accepting data from an external measuring device via the serial port. The grid is also open to editing records as well. Part of the process of making this grid user friendly is to intercept the "enter" key and move to the next cell until there is a value in the cell. This is only for some cells, other cells can be blank. I have worked out how to intercept the "enter" key from another post on this forum. Here is the code:
I need to display the column header and cell value of the clicked cell in the data grid.

I have a DataGridView that has some columns with dates. It binds to an in-memory Datatable which gets loaded from an string array of data passed back from the backend Some of the rows returned have nulls for the date columns. Solution 1: If I define the Date column in the DataTable as "string" I can easily convert those nulls to empty strings and display it in the grid as empty strings (desired results). However, if the user clicks on the date column header to sort by date, it doesn't order the rows as you want. You get a purely string sort order. Not acceptable
This is a VB .NET application where we are showing the output of a SQL statement in a Datagrid view. using .NET 2005.We need to get the seperators of the headers on the grid control to be the same colors as the GridColor on the form. See the picture below:We've tried looking through all of the properties of the DataGridView control, and found some interesting things that looked promising such as the DataGridViewAdvancedHeaderStyle, and DataGridViewHeaderBorderStyle, but none of it seems to allow you to change the colors on it.Does anyone know how to do this without remaking the entire thing with a GDI+ control?
I have 1 datagridview and i want to transfer all records to another datagridview, how can i possibly do that. Newbie here. This is my code in transferring 1 record to another datagridview to another one.
i have datagridview populated with stock code, name and description.And i have docked my datagridview to the bottom. so whenever the form is resized, the bottom section will be occupied completely with the datagridview.But i want to display one extra empty column and multiple empty rows to completely fill in the datagridview.The extra empty column width will be adjusted to the right end side of datagridview.And the no of empty rows will be generated based on how many is required to fill up to the bottomSo that i can create datagridview with full column and row even though some columns or rows are empty.

I was knowing that For Each loop can only be applied to those classes that implement IEnumerable interface . But recently i accidentally wrote a code that is using For Each on my class's objects collection and my that class is not implementing IEnumerable interface .Below is the sample code that i am testing on :
Sub Main() Dim personList() As Person = New Person(2) {} personList(0) = New Person("s1", "s2")
