View 2 RepliesI have a windows application that has a tab control with 5 different tabs. Each of these tabs has a datagrid view that is populated with data on form load with data from SQL Server. I have an event handler for the datagrids for CellValueChanged that appends an asterisk, "*" to the tab, when a change is made, this is meant to mimic the same behavior in VS or SSMS. The issue that I have just realized is that on page load as the datagrids are populated this event handler is raised thousand of times. I have included an If Then statement to exit the sub if it occurs during page load, but am concerned about the performance implications, if any. Is there a better way to handle such functionality? Possibly a way to ignore the event handler on form load? If not is there a negative impact leaving this functionality in?

View 2 RepliesNew to VB.net, and trying to re-factor an 'old-skool' ASP page where all the page logic is happening on the .aspx page itself, to code-behind. Basically, I have a button that has a state, either on or off. If on, I set a hidden field to 1, if off, I set it to 0 (the default when a user visits the page).The goal is to simply change the message I am sending to the user.[code]The above code produces the following effect: when I click the button, setting the state to 1 and the page reloads, in Page_Load, I am getting zero results from the If dlList.Items.Count > 0 Then check, and thus am showing the 'No results' message, but the actual asp:DataList on the MyPage.aspx page is returning results... and then if I click the button again, setting it back to 0, in Page_Load, the datalist is now returning results, so I set the text to 'Results', but again, the control on the MyPage.aspx page behaves correctly, and shows no results, as expected. Now keep in mind that the above works perfectly in terms of checking the number of results if I move the If dlList.Items.Count > 0 Then page logic out of Page_Load and back to the MyPage.aspx file, it all works fine (i.e. results when state = 1, none when state = 0)

View 3 Replies<Visual Studio 2008 / VB.NET /SQL 2008>. I have a form that populates data when Load event occurs. The problem is it looks like a slow motion movie when the form is loaded since there some quite amount data is populated. This is happen because I put a coding to populate data on Form Load event. Is there anyway that I can prevent the slowing down of form load event? I guess best thing is load form completely and trigger populating data.

View 2 RepliesI have an asp.net website that is using update panels on the page that i cant get to reload from the server. I have this for the disable page cache on the master page.

I have a page to which i send some variables with the GET method. In my VB back-end i get those variables using Page.Request.QueryString("<name>")If i then use the IsNumeric method to make shure it is an numeric string i get True back as value.
When i then try to transform the string to an Integer using val, cìnt, Integer.Parse or cType I get an error saying that my string could not be converted to a integer.So i made an error page which gives me all the info i need to deal with the problem (view below) Exception Message: Conversion from string "" to type 'Integer' is not valid.
[Code]...
IsNumeric confirms that it is a numeric string and that it should be convertable to an Integer. So why won't it work. I don't think that my code should provide any extra information because it only gets the querystrings, uses IsNumeric and then tries to convert them.

I have a BindingNavigator and combobox tied to the same BindingSource. I want to allow the user to confirm a delete after hitting the delete button of the navigator.

im having a issue where not all the data from my dgv is being loaded into text boxes on a 2nd form. What im doing is using the "DataGridView1.CellDoubleClick" event to open another form and pass the selected row into seperate columns, this works great but as i added more columns to the DGV it seems that the form is loading and not all the data is loading into the text boxes. Is there a way to halt the opening of the 2nd form until the loading is complete? i tried to simple "sleep" at the end right before the form is made visible but that didnt work. heres the code im using to load the DGV into text boxes, there are 16 columns, this is just the first one:
Code:
Edit.Item.Text = DataGridView1.Item(1, i).Value
as i said before, 13 or so of the 16 work fine, its the last few that refuse to load
Add the items from text file into TextBox and ListBox.[code]...
Where, ";" is the Delimiter and data is just one line only. "A" has to load in TextBox and "Cat,.....,Bird" has to load in ListBox, one line per animal.I've already read the text file and load "A" into text box. But couldn't figure out how to load rest of the data into list box.
I have a datagridview which have 5 columns. The name of the columns are T,C,F,S,H.

T236C1.2F029S48H2000

So i want to display this data in datagried view. I must display the number beside T to T column, the number beside C to C column and so on. It should only display number in the respective column. It should not display the T,C and so on.
I don't want to show the data to the user which is not related to him. So, I need something like the following:
SELECT * FROM Projects WHERE ResponsiblePerson='Sudhakar Reddy' But, as I am using the BindingSource control to retrieve the data, I don't know how to do it.
The following is the code on my form:
Private Sub ProjectStatus_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
