SUMIF Calculation (similar To Excel) In Datagridview

Mar 2, 2010

I have written a code that performs calculation similar to SUMIF function used in excel. My data is in a datagridview and is all dynamic. My data is in the following format

X1 X2 Yj
1 1 11
1 2 12
2 1 13


I am getting a PE value for every cell in the code. How can I modify my code to get the results above. Kindly guide me through it, I know I am probably missing a minute detail somewhere but I am really struggling with this.


Make A DataGridView Similar To An Excel Function?

Jul 2, 2010

I am trying to essentially convert an Excel spreadsheet into a Windows Form. On the first worksheet I have setup an IF statement to work as a search function =IF(C10="","",VLOOKUP(C10,'Price List'!$A$2:$D$40008,2,FALSE)) to read a price list on a separate worksheet. It works by taking a partnumber then puts the description in the next column (description column) and then the price in the "price each" column then finally totalling the row based of the quantity selected (see below).[code]...

Use A Function In Vb Similar To Vlookup In Excel?

Jun 22, 2012

een using excel extensively. In excel I use vlookup function to connect and retrieve data from other workbooks. I want to know how I can do it in VB. So far I have created a form.The form has say three text boxes viz (i) A unique Number (ii) Name (iii) Address. I want that when I write the unique number in the text box for unique number the other two text boxes i.e. of Name and of Address should be auto populated. I have also established and tested the connection with the access database file using ADO.NET. I do not know whether I need to write an SQL or LINQ query for this purpose or I should write some codes. What should i do it and how should i do it?

Bind Combobox Similar To Datagridview?

Mar 26, 2010

I have combobox in a form.  The combobox is bound to a table and displays the list of values as expected. What I want to do is also bind the combox to another field in a different table similar to the way the datagridview with combobox works.  That is the dgv is bound to the combobox column but the dgv's bound value sets/reflects the value selected by the combobox.  I can't figure out if this is possible with a standalone combobox.

Office Automation :: Excel Throws Exception In Set_Calculation(Calculation Property)?

Jun 17, 2009

Error: System.Runtime.InteropServices.COMException (0x800A03EC): Exception from HRESULT: 0x800A03EC is thrown after execeution of Microsoft.Office.Interop.Excel.ApplicationClass.set_Calculation(XlCalc ulation RHS)

Out of nowhere COM start throwing exception when I set change excel's Calculation property. Line of code that followed set_Calculation was.Workbooks._Open. This used to cause exception every second try. Than I changed order, first open workbook and than set calculation property. Amount of exceptions start decreasing than I added thread.sleep(200) and exception is not thrown anymore. This happens only on one some of user machines while others are fine.Application itself is single threaded so this delay should be of importance if and only if set_Calculation is executed asynchronously. What I'm missing here?

VS 2010 Perform Calculation After User Input On DataGridView?

Oct 6, 2011

I have DataTable, and is bound to DataGridView. So, when the user inputs some values in 4 columns, it would calculate the sum and put it in the last 2nd last column.

Here's the code that I'm experimenting:
Private Sub DataGridView1_RowLeave(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.RowLeave
Dim i As Integer
Dim intTotal As Integer = 0
For i = 5 To DataGridView1.Columns.Count - 3


So, basically it should sum up certain columns when the user enters numbers into it and then display it in the last column.

.net - Going From Excel To A DataSet Or DataGridView

Jul 28, 2010

I have data that I'm taking from an Excel sheet with the ultimate goal of displaying in a DataGridView.

Currently I am just going over the UsedRange of excel data and plugging it into a datagridview. This works fine, but can get bogged down when there 100+ rows of data.

I have also toyed with going from excel into a dataset (using the same wasteful method), and as expected it takes about the same time to load the data. Maybe use the XML from the Excel file?


Some Additional Information:

This is a WinForms application and the user will be picking and loading the excel file at run-time.


The Return of Some Additional Information:

The Excel file is located on the user's pc. The general assumption is that they will be loading different files each time they use the application. [not sure if this helps, but might be good to know :)]

DataGridView Add Lines From Excel?

May 27, 2012

I am required to make a program for a small company that reads data from an Excel 2010 file. I have no issues reading this data into my DataGridView control and displaying it for the user.

However, one particular column header is titled "Complete", to which the entire column will either have a "Y" or "N" value. What I want to do is to fill the entire data set from the Excel file (I have done this already), but I need to only display those rows that have the "N" marked under the "Complete" row.

I imagine this would require a For...Next loop based off the DataGridView1.RowCount, but I cannot figure out how I would add just one particular row at a time after checking for a "Y" value in that column. I am only familiar with filling the entire DataGridView.

I included a picture of a sample of what this program would look like (this is how the customer wants it), in case my explanation was not enough.

DataGridView To Excel File?

Aug 21, 2010

So I'm working on this project. I got around 60 images or so which I need to OCR, then I'll be inputting that data into my program which formats it and inputs it within this DataGridView. Now, I need the same data to be exported into an excel file. I saw several tutorials online but none of them are current (for VB 2008 or 2010). Either that, or they're not for VB.NET Windows Form Application. [I'm using VS 2010]

I'm fairly new to Datagridview as well. Just learnt how to add data to datagridview using this tutorial: I was hoping you could help me out with where to start once I get my data all set up in the datagridview?

Exporting A DataGridView To Excel?

Mar 13, 2006

I have a datagridview(DGV) which contains data based on a user selections from a pre-defined dataset

In point form:

User starts program

program builds datatable

user opens file and program read all data from file into the dataset.datatable

user defines the data they want to see

program displays datagrid based on dataset.datatable and user choices. (basically it displays the whole dataset and removes unwanted columns

I want to be able to export the datagrid to excel (not sure which method yet). I have tried the excelexporter component i found somewhere on the msdn forums (it exports the data to look exactly like the datagridview) but its painfully slow. It exports something in the region of 100 records per minute. Most of the time, the datagridview can contain anywhere from 3000-32,000 records. As such, at 100 records per minute, the excel generation can take updwards of 50minutes. Unacceptably slow for the purposes of the program.

What do people recommend as the best method to quickly dump the contents of a datagrid into excel. By quickly, im talking at the speed of about 10,000 records per minute. In all honesty, anything over 5000 records per minute will be fast enough, but the quicker the better!

Is there a way of creating a new dataset.datatable that is built of the contents of the datagridview and then building an excel sheet by connecting to the new dataset?

I would like to be able to export to Excel 2000-2003 at a minimum, but if i can do excel 97 as well it won't hurt.

Exporting To Excel From DataGridView

Jun 22, 2010

I am filling a datagridview with very lengthy results. Roughly 60k rows on average. I am filling them via an oracle database using a table adapter. The records then have a filter placed on them in the datagridview so the results displayed are a bit different.

My problem: I built an export to excel function which populated a dataset and then red through it and wrote to excel. Bad idea with the amount of records I am using. I tried just writing the records straight to a csv file using streamwriter but I don't very much like this way.

My proposal: I would like to fill an array from the datagridview and then be able to dump the array into excel. However I am having some trouble finding examples on creating an array from a datagridview.
