DataGridView - Programmatically Select A ROW Based On Values Find In The Grid?

Nov 19, 2010

I have a DataGridView with 3 columns (metric_key, metric_name, metric_value).There are for example, 6 ROWS in this table (6 different metrics), added programmatically (DGV is not bound in any way)

Now, when I assign values in my grid I do:

dataGridView1.item("Metric_value",0).value = "value of the metric in row 0, in the column named "metric_Value".

Getting Cell Values Into Variables In DataGridView Based On Grid Coordinates?

Mar 20, 2011

Im working with a DataGridView with an imported CSV file where the values are delimited with (,).. The grid works perfectly fine. My ultimate goal is to hide the grid out of view from the user and access the data in the grid based on the coordinates of the grid specified i.e (The cell in column 5, row 6 contains the value "Taco") and I want to save that value to a variable...Eventually I want to loop through all the values of a column and save them to individual variables to be later used. So far, this is what I have...

Dim sReader As New StreamReader("book1.csv")
Dim Record() As String
For x As Integer = 0 To 17[code]....

Presently, that will only display the data in column 0, row 0 in those labels...

Note: 17 in the for loop is the amount of columns in the data i provided.. that number will never change.

[2008] Datagridview - Filter The Grid Based On A Product Name

Feb 4, 2009

I have a datagridview that's taking a while to load because my table contains almost 5000 records. How can I provide an easy way for clients to filter the grid based on a product name. I was thinking of having labels with each alphabet on my form and when they click a label it filters the bindingsource according to the chosen alphabet. this seems like an awkward solution though.

Programmatically Select A Row In A DataGridView Not Registering

Apr 25, 2012

If have a textbox that is used to search a datagrid when a user types into it. This seems to be working properly, as the correct row is highlighted when text is entered. However, something isn't quite triggering properly because if I try to get the selected row, using dgSchedule.CurrentCell.RowIndex, it always comes up with whatever the last row that was physically clicked on, rather than the row that is actually highlighted.[code]...

Select Multiple Rows In Data Grid View And Loop A Sub With The Values?

May 19, 2010

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).

Programmatically Edit My Datagridview Cell Values?

Mar 15, 2012

I programmatically edit my datagridview cell values. I use the vertical scrollbar to find the row I want to edit, select the row then click an edit button that takes me to another form where changes to the record are made. I then click a button which saves the changes and returns me to the datagridview form. No problems here.

When I return to the grid, the records are displayed with the first record at the top of the grid. That is, the vertical scroll bar has repositioned itself to the very top.

Is it possible for the datagridview to "remember" the position of the vertical scroll bar so that when I am returned to the grid, the rows displayed are the same as when I left?

DataGridView Cell Formatting - Red Columns Based On Values

Jan 12, 2009

I want to make a certain column of my datagridview red based on values from 2 other columns. I have a "HI" column, a "LOW" column and a "Result" Column which are all strings. Now I want to make the result column red if it's values is less than the "LOW" columns value or if it's value is greater than the "HI" columns value. I tried the following code but something is wrong because cells that shouldn't be red are red:

If dgvTests.Columns(e.ColumnIndex).Name.Equals("Result") Then

DB/Reporting :: SQL Select Query In Form - Form With A Datagridview That Displays All Of The Values

Mar 26, 2008

I am using VB2008 Express and a MSSQL Server 2005 db by the way! I have a comprehensive SQL statement, which should fill my Grid:

DECLARE @Sum NUMERIC(9,2)
SELECT @Sum = SUM(I_LS.lmenge)
FROM dbo.lfs AS I_L

[CODE]...

Now here is my problem! I want to have a form with a datagridview that displays all of the values I am querying. This shouldn't be a problem I guess. However, I have no idea how I can integrate two textboxes that can be used to enter the selection criteria (WHERE I_L.lfsnr LIKE '%1253') AND (l.sped_journal = '11-08')[/SIZE]. I have googled and read many threads so far but didn't stumble upon anything that would suit my needs and answer my question. Maybe it's just too elementary!? By the way, it is very important that the input of textbox1 ((WHERE I_L.lfsnr LIKE '%1253')) is linked to 3 positions in my SQL query to define the search criteria!

The worst thing is that I don't want to have a bindingnav displayed! I do not need any delete, update or add functions just the select option, however!
