View 4 RepliesI'm trying to write small piece of code in Visual Studio (VB.net) that will change value of a particular field of the database for all highlightetd rows. So, I'm running my form, which displays some data from the datatabse. I then highlight some rows (holding Ctrl and clicking). Next I click a button that will trigger a value change for all the highlighted rows (only). Say, I want to change the "Name" column's value for all of them.

I have a datagridview linked to a dataTable loaded from a sql server via an adapter.I wish to sort one of the column: Filenumber.The Columns is a string. For example:
M-099
M-756
M-777
M-1000
But when i sort the columns by using Me.DataGrid.Sort(DataGrid.Columns(9), System.ComponentModel.ListSortDirection.Ascending), it turns out to be:
M-099
M-1000
M-756
M-777
I would like to know how to sort it like:
M-099
M-756
M-777
M-1000
How should i go about it? I've thought of getting rid of the M- in front and putting it into another column, but it makes filtering nuisance.Also, is it true the a custom sort via an IComparer is only applicable to things without a binding source?
I am using VB 2010, .NET Framework 4.0 and am currently loading an unbound datagridview control from an object. Once I've added all the rows, I want to automatically resort the rows based on the values in the first column, which is a textbox column.
If I click on the column header, the sort works. However, I want the sort to automatically take place once the grid is loaded without clicking the column heading to sort. This would also apply if I add a new row to the grid - I want the grid to resort automatically after the row is added, to display the row in the right spot without clicking the column heading.
I have a database that dynamically loads from Access into a datagridview. I have to enter data manually into one column in this datagridview. I need to be able to perform calculations to this data, for example I need to sum the data in this column, sqaure it and substract it from individual sqaures of the data in the cells. I should be able to sum it sum(22,33,44,53,67,23)^2-sum(22^2,33^2,...23^2). The number of columns keep changing depending on the database I choose to load, so I need to code this dynamically too. I am not really a VB person. I did the same in excel using Visual Basic and I am trying to do it in this Visual Basic environment.I built a tool in excel(VBA) that do some statistical calculations and data analysis and I am trying to build the same in Visual Basic.

View 4 RepliesI have two rich text boxes, and two buttons on my screen. The first button grabs HTML from a URL and then converts the HTML to XML which resides in rich text box 1.
The second button is to grab the XML from the rich text box1 and then parse it to grab all the input elements by their ID.
My issue is that my parser isn't doing anything. My guess is that I'm not quite getting the XML from the first rich text box.
What would be the best way to grab the XML from a rich text box load it into memory and then parse the XML to grab all the ID tags?
Here is my code --
Imports mshtml
Imports System.Text
Imports System.Net

I want to have my current row stand out as the current row by virtue of the background color.I also want my current cell stand out from the row color.
in other words i want to controll the background of the current cell as well as the current row, and have these colors different from each other as wel as the background from the non current cells.
I am getting confused with the notion of the current row vs the selected row.I have tried messing with the default row style.selectedbackgroungcolor as well as the same for the default cell style, but cant get it to work the way i want.
i can almost get it if i set the selection mode to full row, but then cannot get the current cell to have a different background color.
I have three tables in SQL server which I would like to show and access on a form. Table 1 contains account data, address, contact details etc. Table two contains data attached to a Person, tel no , Mobile no, Email etc. Table three contains details on what awards the person holds, i.e. one person can hold several awards.
Therefore I have a one many relationship between the first two tables and a one many relationship between the second two tables. This is set up in SQL
The first two tables are shown on a form, table 1 via a set of text boxes, table 2 via a datagrid control.
I would like the functionality whereby I could select a row in the datagrid showing the persons name and find the Persons_ID number then use that as a filter to a second datagrid view so that only the selected persons awards show in the datagrid.
How to get if the datagridview has a seleted row or current row? Ex. If datagridview1.HasCurrentRow = False then Messagebox.show("Please select a row first prior to click "change" button.") end if
