I have a tab control with 4 tabs. At form load time I determine which tab I need to have the focus (which one to select). I have tried using TabControl.TabIndex = 2 to set the desired index and TabControl.SelectedTab = TabControl.TabPages(2) as well as TabControl.SelectTab(SoftwareUpdateTabPage), however, none of these seem to work at load time. The tab enter of the first tab always seems to be called. Is there a way for me to select the tab I want in my form load function?
The second part is how do I disable (so the user cannot change to another tab) the other tabs at form load time?
I have a aspx page, in that page i have an Iframe. In the Iframe i do some stuff in code behind and when it is done I would like to do a postback from the aspx. In other words, Is it possible to do a postback programatically from the code behind of the iframe to the parent page?
View 4 RepliesI am able to insert a textbox into a Word document using the below code:
Dim opProcedures As Word.Shape
opProcedures = oDoc.Shapes.AddTextbox(Microsoft.Office.Core.MsoTextOrientation.msoTextOrientationHorizontal, 0, 0, 456.75, 24.75)
opProcedures.TextFrame.TextRange.Text = "Operational Procedures"
This adds a textbox to the first page of the document however even when I change the first (top) parameter I am unable to move the textbox onto the second page (only lower down onto the 1st page, any greater values than the height of the first page an it disappears).
How can I get the textbox to appear on the 2nd page of the document?

I've a problem with DataGridView component when trying to set the value of the CurrentCell. What i'm trying to do is :
I've a DataGridView With values. I want to make a button in my forms and when clicking on it I want to change the selection from the current row to the next. To explain more, by clicking my Button I want to simulate the effect of a mouse click on a DataGridview.
I am using Visual Basic 10/I have 2 datagridview tables. The main datagridview can be edited by the user; adding/removing rows, changing data in text/combo columns, sort, etc. 2 columns from the second datagridview are a carbon copy of 2 columns from the main datagridview. I have achieved this by binding both datagridviews to a dataset. So that when I edit the main datagridview the effects are automatically replicated in the second datagridview.
Before I bound the datagridviews to the dataset I had a fully functional system to save the content of the datagridview to a text file and read it back in. This has now stopped working with the error message 'Can't edit a bound datagridview programmatically'.
I have a unbound datagridview for which i want to add a new row at the bottom when a user selects a value in the 2nd column of a 9 column DGV. The issue is that i have a default value (0.00) programmically entered into the last row once this 2nd column value is entered. When i call DGV.rows.add() it places the new row at teh top, but when the user enters or changes the last coulmn value then a new row is added at the bottom. I want my programmically added row to be at the bottom and have not found a way of doing this.
PS. What is the logic behind this different behavior on adding rows?
If have a textbox that is used to search a datagrid when a user types into it. This seems to be working properly, as the correct row is highlighted when text is entered. However, something isn't quite triggering properly because if I try to get the selected row, using dgSchedule.CurrentCell.RowIndex, it always comes up with whatever the last row that was physically clicked on, rather than the row that is actually highlighted.[code]...

how to connect a SQL Table to a DataGridView that was previously created programmatically. Basically, at run-time the user names and creates several empty SQL Tables and DataGridViews. After that the user selects from a combobox the name of the SQL Table and DataGridView that they want to import data into, then clicks a button named "Import"...after clicking "Import" the user navigates to an Excel file, chooses a worksheet, clicks a "Continue" button and then the code successfully connects to the Excel import file and SQLBulkCopies the data to the SQL Table...next I need the imported data in the SQL Table update to the DataGridView...this is the part I can't figure out.
The challenge is the datagridview isn't hard coded it was created and named programmatically at runtime. So now the user selects the name of the SQL Table the data resides in and the name of the DataGridView from the combobox "moduletableCB" and I need the code to update the datagridview.

How do you change the column type in a datagridview programmatically? I have several tables that I want to allow the user to update using the same form. Depending on the table, I need to change the column type to a checkbox instead of text. Following is the code that I run (just exchanging the table name and column #). Everything works well as long as I don't try to change the column type.

I programmatically edit my datagridview cell values. I use the vertical scrollbar to find the row I want to edit, select the row then click an edit button that takes me to another form where changes to the record are made. I then click a button which saves the changes and returns me to the datagridview form. No problems here.
When I return to the grid, the records are displayed with the first record at the top of the grid. That is, the vertical scroll bar has repositioned itself to the very top.
Is it possible for the datagridview to "remember" the position of the vertical scroll bar so that when I am returned to the grid, the rows displayed are the same as when I left?
I need to highlight rows in an unbound datagridview at runtime.I've tried to highlight right after adding the row using dgv.Rows.Add(row0)dgv.CurrentRow.Selected = True

I have a button on the screen 'Next' which performs some activities, but at the end I want to move to the next row in a datagridview to show the user what record they have moved to. I expected this to be easy, using the following code:

DataGridViewPtList.Rows(CurDGVIndx + 1).Selected = True
BUT.... Yes the highlighted record is the next record using this, however the selection (where the little arrow indicator is) stays on the original row. The selector needs to move too!
