View 5 RepliesI have more than 30,000 rows in a table. It takes a lot of time to load all the data in the gridview. So I want to display 100 rows at a time. When I click next page button, another 100 rows should be displayed. When I click previous page button, previous 100 rows should be displayed. If I type page 5 in a text box, then I want to jump over to the 5th lot of rows.
I also want to display how many pages there will be. Can we implement this concept in vb.net [winform] gridview. I am using database PostgreSQL.
I'm working on a VB.Net windows application.In the top half of the form application, I have a vendor number with a "GO" button and in the bottom half I have a list of tab pages. We have built the application to only go to the database and display data when the tab page is selected by the user. If I'm in one of the tab pages, and I change the vendor number and click the GO button, the data on the current tab page goes blank (it does not refresh). I have been told that I have to find a way of programmatically clicking on the tab page's tab a second time. How do I do that? I've tried using _Selected event, _Selecting event, _Click event. I've even tried to do a .Focus() on the tab page itself. Nothing seems to work to reload the new data without clicking off of the tab and back onto it manually.

View 14 RepliesI have written an application which extracts a list of URL's (currently in Internet Explorer cache) from an XML file and displays them in a data grid view. From here i would like to launch Internet Explorer in a hidden mode and capture an image for each of the selected URL's in the data grid view. Is this possbile? If so what is the best way to go about it?
View 2 RepliesI have a form that contains two datagridview. I need to load the form first or anything that shows a "loading please wait.." form while the two grids load.Basing on your experience what are the ways to do this?
View 1 RepliesI have a form that opens another. I want the second form's checkbox to match the first form's after the second has loaded. I tried using MyForm2_Load, MyForm2_Activated and MyForm2_Shown but the checkbox checked state of the second form always changes the checkbox in first form. The code below works if I check the checkbox in either form, the other changes to match it. The problem occurs only when MyForm2 is first loaded. How can I get it to work the way I want it?

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.

EMP_IDTextBox is from datasource on a form, and I tried to show messagebox to see what the value is
Whenn I try case 2, the messagebox shows me correct value, but not for case 1. It shows me no value even though there is a value.
How do I do it and what is the diffrence between case 1 and case 2?
I tried with a textbox which is not binded to datasource on case 1, then that shows me the value.
Case 1
Public Sub Save_Data()
Dim L_EMP_ID As String = Me.EMP_IDTextBox.SelectedText
MSGBOX(Me.EMP_IDTextBox.SelectedText)

In my userform I have a WebBrowser control to load PDF files. I have added a FolderBrowserDialog to allow user selection of drives and or folders.
What I am trying to do now is after a file has been selected and viewed, the user may want to change drives and or folder locations. How do I remove the current contents of the WebBrowser control to be a blank screen (just like when the app starts, its blank).
I want to make a message box appear to show that the webpage has already loaded. I have used the code below:
Private Sub Button11_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button11.Click
WebBrowser1.Navigate("[URL]")
If WebBrowser1.ReadyState = WebBrowserReadyState.Complete Then
MsgBox("yahoo is now fully loaded ")
End If
The message box is not showing at all . I have looked for "DocumentComplete" but can't get it working ..

I am using VB 2008 express and would like to know, If i can Replace a string inside of Javascript on page loaded into axWebBrowser so i can then execScript that function. The specific string i wish to replace is "_new" to "_self" this is so when i call the function it will load in the same page instead of popping into a new web browser. Also, is there a way I can just insert my own javascript function in the DOM as well?
View 3 RepliesThis is a VB .NET application where we are showing the output of a SQL statement in a Datagrid view. using .NET 2005.We need to get the seperators of the headers on the grid control to be the same colors as the GridColor on the form. See the picture below:We've tried looking through all of the properties of the DataGridView control, and found some interesting things that looked promising such as the DataGridViewAdvancedHeaderStyle, and DataGridViewHeaderBorderStyle, but none of it seems to allow you to change the colors on it.Does anyone know how to do this without remaking the entire thing with a GDI+ control?
View 2 RepliesI have a datagrid view containing a customer list that if if double click on a row it brings up a customer maintenance window. Once I hit a save bottom on the second form how can I automatically update the database, refresh the grid on the initial window but remain on the same row on form1 that I double clicked on in the first place. Currently I am re-loading the datagrid on the initial form with all the data once I close the second window down.
View 6 RepliesI have the below code that i am trying to have two datagrids with a grid splityter in the middle. The split seems to be working fine but the issue i am having is when I populate the datagrid it is growing in height and changing the splitter instead of leaving the height alone and adding scroll bars.
What simple thing am I overlooking?
<Grid x:Name="gdHistory" Grid.Column="0" Grid.Row="2" >

I have tried to add a splash page to my app. I've tried the MinimumSplashScreenDisplayTime" Property, but it doesn't seem to work. (Don't bother trying to explain that to me again. I've given up on that.) Therefore, I will just work the splash screen as a form (like everything else). start it when the application starts and close it (automatically) after 4 seconds?
View 4 RepliesI 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.
I have two data tables within my data set that are loaded onto my form on form_load using statements written in code (not the designer. When I change a value for the first table via a text box the change is made to the data set. But when I try the same for the second table, the change doesn't remain in the data set when I switch to a different company and come back. I query the second table using the primary key of the first table but no code is needed when I change the values for the first table so I don't understand why the same doesn't work for the second when I change a value via a data-bound text box....
Here is my code that initially binds the data:
'This is used to read our data from the data base
Public Sub Read_Data_SQL()
Call Clear_Bindings()

Here is the code I call when the selected index of my company combo box changes to have the second table reflect that of the first:
