In my form there is a Data Grid. When the datagrid is populated, I like to display the total number of records in the grid and sum of a particular column of the grid. Is there any method to be invoked?
What could be the code if I want to add the value in the 1st row and 2nd row. I want the total to be displayed in Label1.text. I'm just a beginner in Datagridview.Anyway, I didn't put the code because this is just a very small portion of the program that I am creating.
View 2 RepliesI have a DatagridView control. I have 4 columns. What I want to do is allow the user to add rows and enter data into the grid and then click a button and save the data in the Gridview to a table. I can't find any information on how to do this
View 4 RepliesI want to know if it is possible that the data grid view (DGV) rows dont stat at the top of the DGV, but start at the bottom. When I select de DGV it comes by default with the first row at the top, just below the column header, when I add a new row, it comes below the first row. But I want the first row at the bottom. And if I want to add a new row, it will come above the first row.

Have you design a program that the user choose which material and a number of students in this article and the class and a number of students in grade
For example, if the number of students in Grade 10 students
The number of students selected for the Article 10 The English language program to include material in a cell alone < English >
Though the number of selected students of history 5 and the number of students selected for geography 5 The program develops articles on each Some
History
Geography
To signify that we have five students who went to the study of history goes the rest in the same proportion to the study of geography

Let's say I have ten rows on a data grid and I have changed data of three rows.
I am trying to save data by Linq for those three rows, but I am not sure how it is possible to save them.
I can do it by looping whole rows by checking each row for any change.
Is there any smarter way rather than looping by code, such as For Next.
Let me know if I use the wrong words when discribing my situation, I am a student in college learning VB. I have a a datagrid bound to a table built in sql server 2008.

I am trying to make an address book and need help. I am in the middle of making a search function for the program and I've got that working fine. What I would like to do is take the row that is selected from the search results and make that the selected entry for the main form. To explain what I mean I will include pics..
View 6 RepliesI 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 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 a grid containing rows flagged with different priorities. I want to color the high priority rows red, low ones blue, etc. I'd like to set the shade based on a mathmatically calculated gradient rather than arbitrarily assigning colors to specific priorities. How can I extract a single color from a single point along gradient?
View 1 Repliesi 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.
View 1 RepliesThis 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?

View 3 RepliesI have a databound datagridview.I have disabled automatically adding new rows to the grid. The datagridview is bound to a datatable.In it,I have also set the Protected Overloads Overrides Function ProcessCmdKeyto handle and process the 'Enter' keypress.When the user presses Enter within the Datagridview,I want the grid to add a new single row to the bottom of the grid.I have tried several methods to do so,but the grid always adds the new row to the top of the grid instead of to the bottom.I tried posting this issue in the Windows Forms Data Controls and DataBinding board, but didn't recieve any help there, that's why I'm posting this here instead.The only person to help me there said she couldn't reproduce my issue, even when I supplied her with the exact code I was using.I believe there is more than one way to implement this adding of a new row to a datagridview programatically, and browsing through the various msdn forums, I came across several and tried implementing them all, always with the same result.I don't remember all the various implementations I have tried, but here are my few most recent ones:(This is within a class I created that inherits the datagridview. This custom class was the only place I could specify the ProcessCmdKey function, it doesn't work in an instance of the datagridview instantiated directly onto a form. That is why I'm using the me keyword to refer to the datagridview)#1)

I have the below code that i am trying to have two datagrids with a grid splityter in the middle. The split seems to be working fine but the issue i am having is when I populate the datagrid it is growing in height and changing the splitter instead of leaving the height alone and adding scroll bars.
What simple thing am I overlooking?

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.
