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
I need my program to output and input a customer ID and sales amount multiple times. I need it to display both outputs, customer ID and sales amount, on mulltiple lines. It also will need to accumulate the sales amount and then display the total sales. it should look something like that.[code...]
I think that I was supposed to use a messagebox but wrote the program a different way. the form.vb was already locked, but I added two text boxs. Not sure if I did this right because I need to enter multiple sales for one customer ID.[code...]
First form has 1 listbox and 2 buttons. Second form has 1 datagridview and 1 button. The first form opens the csv and list the location+filename of the CSV file. When the CSV files are listed in the listbox, the user can edit the selected csv file in listbox through edit button, when edit button is pressed, the second form will show as dialog and automatically opens the CSV files in DataGridView. The user will edit some fields and save and the second form will autoclose. Now here's the problem, when i select another CSV file in the listbox and press the edit button, the previous CSV still shows, even other CSV files I select, still the previous CSV file was showing.
I'm working on a project where I've loaded a database into a DGV. I also have an additional unbound checkbox column for the users to select entries with. I have code in place to read the selected rows and save them into a CSV string, which is then saved in the usersettings. All this works fine.
PROBLEM AREA: I'm trying to reverse this effect so that when the DGV loads, the checkboxes that the user selected previously are checked (and the others left unchecked). I've debugged this extensively, and using watches have confirmed that all the values in the loops are right, and the conditionals are all kicking correctly, but it seems the code I'm using to actually check the boxes doesn't work. I've searched dozens of web pages, msdn white papers, and forums, but no suggestions will check the darned box. Below is some example code.[CODE...]
In debugging, it seems the value for the Cells IS changed, but the checkbox never gets selected. The try/catch was just to pick any error messages (but there are none with this code). What am I doing wrong here?
I am trying to display unbound data in a DataGridView.I set up columns already design-time. I am at a loss for creating code that adds a new row using the column schema that was created in the Designer?Something like this?
dim newrow as DataGridViewRownewrow.cells.item("name").value = "text here"datagridview1.rows.add(newrow)
I get an error saying the 'name' column was not found?
I have a form created which an unbound datagridview that has three columns. "Position", "ID", "Name". The data is being added at runtime into a database upon the forms completion. (I don't want to add unnecessary rows to the database in the event a person clicks Cancel.) What I need to do is on the deletion of a row in the datagridview, search through the rows "Position" for a "HJ" value. If it's not found, change the "Position" value of the first row to be "HJ".
I am trying to transfer the entire contents of an unbound datagridview (excluding the headers) to the next row of a bound datagridview. This is what I have so far but I'm not sure if I'm on the right track or not.
vb.net Dim rowcount As Integer = dgv1.Rows.Count dgv2.SelectAll()
I have an unbound datagrid control I am using to store inspection information. The program records the information from the user, validates the values, and saves it into a database. It will then show the last inspection data in the datagridview. The user has the option of doublclicking a row and changing values and resaving the row. The number of rows per piece inspected varies, so that is why I used the grid to show the inspection data, however, they want to see a running total of each inspection point at the bottom of the grid so when they add the new values, it will update the running totals. I can see how to add a new column for a running total, but the layout requires the sums to be in the last row of the grid. I can add the row to the grid, but I need to make sure it stays at the bottom of the grid when I add a new row, and if possible freeze the row so it is always visible like excel. The program we are re-writting is excel based so this functionality is critical for the inspector to see the running totals for each inspection point.
I have an unbound datagridview with three columns already setup. I load data into a dataset. I bind the dataset to the datagridview. My issue is that new columns for the dataset is added to my datagridview. I would like to place the datainto the predefined columns. I have tried this:
I have an unbound Datagridview which gets its data from an array from an Excel sheet. I give the user the chance to amend this data in a Datagridview. I then need to know if the user has changed this data before processing it further. I have in vain, tried to use IsCurrentRowDirty, IsCurrentCellDirty, looping through DGV matrix etc. It seems that because the DGV is not bound to a dataset then the normal properties like HasChanged and the 2 above don't seem to work. Here is my attempted code which is not working:
Dim DGRow As DataGridViewRow Dim DGCell As DataGridViewCell For Each DGRow In DGV_ReviewDetails.Rows
I am using VB 2010 with an Access 2010 database. The Access table is the data source for a DataGridView created by dragging the table from the DataSet onto the form. The table has 3 columns - First, Last and DOB (Date of Birth). I want to have a column in each row to show the person's age. I added an unbound cell in the DataGridView called Age, but cannot figure out how to fill the cell with the information I need. I tried using the DataName property, but that will only allow me to enter columns already in the grid. I think what I need to do is fill this cell (Age) by a value computed from DateDiff(DateInterval.Year, DOB, Now), but I cannot figure out how to do so.
I am creating a form to display data in a DataGrid that is bound to a .mdb Query. I am semi-experienced in VB6 Programming, but relatively new to VS8 and all of the features. I created the form, and have the DataGrid that displays all of the info in the query. I would like to be able to filter the form to only display data that matches what the user would type into a text box on the form (I have a text box created as well as a command button that says "Search by...").
Additional Info - I do not have, nor do I want, the DataGrid Navigator displayed on the form.
I want the user to be able to type a value in the text box (Rack Number), then press the button (Search by Rack Number) to only display the data in the DataGrid that corresponds to the rack that matches the text box.
For Each row1 as DataGridViewRow In dgvImport.Rows Dim drv as DataRowView = row1.DataBoundItem ' this results in nothing why? Dim row2 as DataRow = drv.Row Me.TblRecBindingSource.Add(row2) Next
I have an unbound datagridview that I populate with data. When the user clicks on the column head the datagridview is sorted - which is fine for alphabetic fields but I have a column that contains numeric fields and goes from -100 to +100. This is sorted incorrectly by the number (all the 1s first then all the 2s and so on, ignoring the minus sign). How do I get it to sort my column numerically?
I'm populating the datagridview at runtime based on user input. The issue I'm having is that the the combobox is displaying blank. The item I need is in the dropdown (I've added it), but I can't get it selected by default. I've tried the display member but that's not working.
