User Adding Row In DataGridView?
Dec 9, 2010
I'm having an incredibly frustrating problem with datagridview that seems like it should have a very simple solution, but I haven't been able to find it yet.I have a form with a datagridview on it that is only usually 1 to 2 rows long but can be much longer. So when the form loads it populates the datagridview with values for however many rows there should be, and there is a blank last row. On the column header on that last row is an asterisk. If you click on the asterisk or anywhere in the blank line, it adds a new row where you can enter data, however, the blank line with the asterisk does not move down to be under it. In fact the asterisk stays on that line, and if you click anywhere on that same line, it adds another row, placing it on top of the one that was just added, and this can happen forever. I have a sub that refreshes the whole table and repopulates, however I can't run it in the new line code with an "Operation is not valid because it results in a reentrant call to the SetCurrentCellAddressCore function." which I can't seem to get past. If I exit the form however and come back in (it runs the refresh on loading), now all the lines that were added show up, with a blank line with an asterisk at the bottom.

I have a DataGridView where Cell_Validating is being done. I have a Cancel button on my form that allows the user to exit out of the DataGridView changes. The problem is that if a cell was currently flagged as in error, I cannot exit and remove columns from the DataGridView. I get the following error: Operation did not succeed because the program cannot commit or quit a cell value change. Is there a way to cancel the validation once the focus has been removed from the DataGridView? Here is my Cell_Validating

how to add an icon to a user control - I'm talking about the icon that shows up in the toolbox. I have found some articles on the Microsoft site, but honestly they are so complicated and esoteric that I simply cannot follow them - it's like every synaps in my brain is misfiring when I try to read it!
I would love to see a very simple example of how this should be done.
I've tried embedding the image into the resources, setting the build action to Embedded Resource, creating a ResourceFinder class (as per MS advice) and then preceding the class with:
<ToolboxBitmap(GetType(ResourceFinder), "ExposureMeter.Exposure.bmp")>
.. but so far I feel like I'm shouting into a cave without a single bat flying out...

I have been set a project from school to design snake in VB.Net but i am struggling to dynamically add the user control which acts as one of the dots in the body of the snake. Every time i add a dot on to the snake the previous vanishes. I assume this is due to me overwriting the previous one by creating a new instance of the object but i cannot find a way of adding a new one in.[code]I have tried using body(i) and other ways of adding a new instance of the object but am stuck.The subroutine will be called up when a new control is needed.

I using vb.net vs2008.
I have a datagridview and two datatables. I am comparing the information in the two datatables. Now, if the data exists is datatable2 but does not exist in datatable 1 I would like to add a row to the bottom of the datagridview and fill in the necessary information.
Can someone give me an idea of the necessary syntax that I will need to accomplish this goal? Also, I know this post is a little vague and if more information is needed to answer the problem I can give it.

I would like to add a row into a DataGridView: The first column is a string All of the middle columns are of integer type (for sorting) The last column is a string All the values above are passed to the Sub by a array (currentRow) of type String. However, the middle values have to a go through a type change to type Integer for sorting The following Sub works perfect except: The number of items in currentRow (the columns) may vary Then the hardcoded dgProduction.Rows.Add() code at the bottom with not work properly because it is fixed with a total of 6 columns. note that the length of currentRow() will not vary during the population of a single population event. Instead it may vary once I have cleared the grid and click on a different date. So all the rows within the grid will have the same number of columns.

Public Sub addRoll2prodGrid(ByVal currentRow() As String)
Dim rowCount As Integer = currentRow.Count - 2

I have a User Control which returns a table of data, which in some cases needs to be looped, displaying one on top of another. I am able to dynamically add a single instance of this by placing a fixed placeholder in the page. I am now trying to work out how to add more than one, given that I don't know how many might be needed I don't want to hard code the Placeholders. I've tried the following, but I am just getting one instance, presumably the first is being overwritten by the second
My HTML
<div id="showHere" runt="server"/>
VB
Dim thisPh As New PlaceHolder
thisPh.Controls.Add(showTable)
showHere.Controls.Add(thisPh)
Dim anotherPh As New PlaceHolder
anotherPh .Controls.Add(showTable)
showHere.Controls.Add(anotherPh)
How do I make it add repeated tables within the showHere div?

For my user system, I require each user to have a unique id. The reading in and saving of the user data is all done, but now I'm focusing on adding new users. In my add user dialog, I have the information fields required to create a new user, one of which is the ID (which must be unique). For this I have created a function that I thought would always give a unique id but it does not. paste the code below:
Function getnextuserid()
Dim id As String
Dim unique As Boolean

I have 1 list view box that has 2 colums. one for the product and the other for the cost. My question is how would I allow a user to add values to that?
My basic layout is, There is a settings window that has about 10 rows of text boxes and 2 colums. I want the user to be able to type in multiple items and prices then hit save and exit for the products to save to a my.setting
and then use this my.setting to bring the users lists up in a list view box.
Since the product and the list price are paired I also need to keep them together in there pairs.

I have a DataGridView that is bound to a DataTable. In this DataTable is a column that contains an image path location, ie; c:imagesmoon.jpg. In the DGV, I'm only displaying 2 columns, the "Name" of the image and the "Image" itself, which basically is the path information. how do I get the image to display in DGV Column? Because even though it's bound...no data comes up when I run the app.

I am trying to add and update data in a db from a DataGridView. I have a save button that runs this code. The code works fine. It figures out which rows are new and add it into the DB and which rows are updated and updates them in the DB. BUT if you press the button again it will add the new row in again. it does not mark the new row as one that needs updating when the button is pressed again

I am having problems adding a new row to a datagridview control in my form. I have a simple formwith a textbox, a button and a datagridview. When the user types in an item number and clicks on the button, the system will populate the datagridview with the relevant data from the database.All these works fine but, when the user tries to add another record, the first record added to the datagridview is cleared off the datagridview before the next record is displayed. I would like the datagridview to add all the records without clearing the screen. The datagridview is not bounded to the database.
