How to increase the number of cells dynamically according to the need?
I'm trying to dynamically create a listview. on reports.aspx user selects a bunch of checkboxes. On the next page, user sees reports.aspx, and should see a table with columns of the checkboxes he selected. My idea was to create a listview, then dynamically change the header row of the LayoutTemplate, then change the select statement depending on which columns selected. This is what I have:
<asp:ListView runat="server" ID="ReportListView" DataSourceID="ReportListViewSDS">
<LayoutTemplate runat="server">
<table runat="server">
[Code]....
Problem is that this doesn't work because i can't put a code block (<%%>) inside the LayoutTemplate. Is there a way in the code behind to edit the LayoutTemplate, or another way to cycle through the Request.Form vars and build the table header row with it?
I have a Windows form which contains a DataGridView within a GroupBox which is within a TabPage which is within a TabControl.The scrollbars property is set to 'Both' so that the user can scroll down to see all available rows in the grid.
I want the Windows Form to initialize to allow the user to see 7 rows but to expanded vertically to the size of 32 rows which is the maximum possible in this application.
Is there a way to size the form dynamically so the Form's Height property can be changed as the DataGridView's rowcount increases?

101
102
103... to infinity

Why did they choose to add a new keyword AndAlso, instead of just changing the functionality of the existing And keyword?
Why would one want to use And, instead of AndAlso anyway?
Is it not just increasing the number of keywords unnecessarily?

How do i make the number in a particular column of an MS Access database to add up by 1(one) each time a button is clicked? I have tried the following code but everytime its clicked, it just seems to "replace" the 1 which is already in the database.

ds.Tables(0).Rows(i).Item(10) = +1
da.Update(ds, "Students")
End If

View 1 RepliesI have a DataGridView that is showing some weird numerical data. For example, my under lying datatable of the datagridview has 4.69, but the datagridview shows 4.6899999999999999995. What is weird is it doesn't do it for every cell in the column. For example, my underlying datatable has 2.66 and the datagridview cell shows 2.66, which is correct. I should note that the underlying datatable column that contains the numbers is of floating point data type which comes from the database column and the datagridview column is TextBox. Here is what the values look like in the database, underlying datatable and datagridview.

I am using VS2008. I worked on this problem for a time, but I was not successful doing it. Below is the VS file.I need to produce a grid of cells and have some random features as shown below which is an example of a world of (500 x 500) units (or any other size and grid size). It contains three areas (of 11 cells, Value of each cell = 108), two green areas (of 8 cells, Value of each cell = 137) and one river. The start point of the river should start from one of the world edges and finish to another one. Please note that number of feature could increase or decrease according to user inputs.The question is, how can I produce these features randomly? To clarify the question, I will read the number of areas from a form. I need these features so that the number of cells should be distributed randomly beside (attached to) each other in the world. The rivers occupy one sequential grid line. My problem is how can I randomly generate the features according to number of cells??

View 8 RepliesI'm working with datagridview.I found an example on the web about creating a datagridview: firs I make my array containing data, then I make a datatable from array, then I make datagridview from datatable.I don't know if it's the correct way but it seems work.In a column I make random numbers for test: for example I have on column "Time" these values: 1155, 1725, 584, 996, 1352.Then I try to sort with code when I press pushbutton: it doesn't work because I have the values:1155, 1352, 1725, 1758 (until now it seems to work correctly), but then I have 584 and 996 values: wrong!Ok, let's try with the manual sorting: same result.I filled cells with "integer" values, let's try using strings, then I used "value.tostring" same result.I also tryed to fill strings with blankspaces to obtain same length, but nothing changed. "1155", "1352", "1725", "1758", " 584", " 996".Then I tryed to fill with "0" values:"1155", "1352", "1725", "1758", "0584", "0996".The same.How can I fill cells values?

I am dynamically creating an unlimited number of background workers and would like to handle errors from them.
In a try statement I am using the following:
