I have one datagrid with bound items and Radio button.
I want a index of the row which i selected by chacked the
the radio button.
i used Datagrid.selectedindex
but it gives -1 every time.
I have a DataGridView containing a large number of columns. I want the users to be able to select multiple columns and then select a menu item to hide the selected columns. For example a user might selected columns 5 through 10 and I want the program to hide those columns. I know how to hide columns, one at a time. I can get the count of selected columns but I have not figured out how to get the index to the left-most selected column. Trial and error is such a slow process.
Considering the huge number of options offered by the DataGridView tool, it would be nice if this forum had a special category for the DataGridView (common to VB and C#).
Finally I got the desired results but it took a lot of coding, looping through the selected cells to find the one with the lowest column index, then a second loop to count previously-hidden columns, then a third loop for hiding the selected columns, stepping past previously-hidden columns and declining to hide frozen columns.
I can't seem to set the selected index or selected value of a DataGridView combobox when loading data from a database. My DGV has two combobox columns which are bound to datatables. The DGV itself is not bound initially. After adding a row, I select a value from each combobox which then populates the rest of the cells in the row. I'm using the EditingControlShowing event to add an eventhandler to catch the SelectedIndexChange of the combo boxes. This all works as needed. My issue comes when populating the DGV with saved data, I need to add the rows and set the selected index and/or selected value of each combo box. I've searched through various forums and articles for the last week with no luck.
I'm using VS2008 sp1, .NET 3.5 sp1 and SQL 2005 sp2 Express.
how do i get the selectedindex/item of a datagridview combobox column?what i want to do is change the back color of datagridcombobox when something is selected from the combobox?So, selecting 'false' will change the color to RED and selecting 'true' changes the color to GREEN.

Isn't there something fundamental like this? Is absolutely everything in VB.NET buried beneath a colossal heap of bureaucracy?

I have a huge text in a RichTextBox. There are few things in that text that I want to pick up and add in a ListBox. Each words I need from that text box are not identical but has got some identical keyword before and after them. Let me give you a sample...
"href ='displayCompany.php?name=BERGERPBL' class='abhead' target='_top'>BERGERPBL 958.00 <img src='tkdown.gif' border='0'><br>-25.30 -2.57%</font></span></a><br></td></tr></table></td><td
valign='top' height='30'><table width="120" border="0" cellspacing="0" [code]....
Here, I need to pick up the words, "BERGERPBL","BEXIMCO", "BEXTEX". They have got identical word "displayCompany.php?name=" before them and "' class=" after them.So how would I do it. I need a code in VB.NET. I use visual studio 2010. Remember, this is just a short sample. The real document is far larger.
P.S. Upper cases are not applicable. Because they may also be in lower cases.
I know this is a very noob question but would it be possible to find a word in my coding and replace it with three lines?

So far I can only replace it with "ex1.Message) Finally Application.exit" but it's going to take me forever to go through my coding to change it. I'm not sure what character I could use to start a new line in between "ex1.Message)" and "Finally" and "Application.exit"

I am working in VB 2008 and I have set up a datagridview to display rows of data which can then be selected. When I select the first row I get the error: Index was out of range. Must be non-negative and less than the size of the collection. When I select any other row the program executes as it should. From what I have learned so far is that the DataGridView has an index of -1 and that it counts the header row as part of the index which is the -1.When I select the first row through either DataGridView1_RowHeaderMouseClick or DataGridView1_CellContentClick the index is 0 for the first record. If the index is 0 I think it would fire off, but I have no idea what is happening behind the scenes. I can check the index, so when it is 0 and the code attempts to access the row, that is when I get the message.On an index number of 1 and up the code executes fine.So, is there a way to re-index the DataGridView, or is there a work around/fix for this issue?

Above event gives me the index,when i select the tab.
The first would be, how would I go about making each index in a list box an integer or decimal value? For example, If I wanted the 1st (or 0) index to = 300 and the next one (1) = 400. The next question that I have is that, if I had two or more list boxes with each index as a certain value as listed above, how would I go about adding up the total for each index that is selected?
View 10 RepliesI need a way of converting the listbox.selectedindex into hex and then writing it to a file(The writing is done using PackageIO.writer).

Dim Writer As New PackageIO.Writer(Filepath, Endian.Little)
