View 2 RepliesI have a TextBox, The situation is that when a user leaves it empty, OK button is disabled. If user types in a value of duration based on days, the button gets enabled. The problem is: let's say the user clicks on text box, types in : 100, and he realizes that he made a mistake, he erase that value and tries to start filling some other textboxes and come back again afterwards, at this level at the time user clicks on other part of form, the value becomes 0 automatically and Ok button is Enabled Now.
Private Sub txtMembershipDuration_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtMembershipDuration.TextChanged
If txtMembershipDuration.Text = "" Then
btnOK.Enabled = False
End If End Sub
Also, how can I control that automatic 0?

I have a texbox that I'm using for a P2P IM program. The box stores all messages but I cannot get it to automatically scroll down to the most recent IM when the box is full and scrollbars are necessary. eg. When a user gets enough messages that they must start using the scrollbars, when a new message comes, the scrollbars reset to the top instead of the bottom where the new message is. Here's the code for adding the message into the box:

Private Sub txtlog_TextChanged()
txtLog.SelectionStart = Len(txtLog.Text)

The code above simply produced no results, it didn't move the scroll bar at all.

I have a strange problem with a DataGridView I'm using which is bound to a table in VB.net
I've added a checkbox column to allow a user to tick a bunch of rows that I can then loop through and save off to a different table. All the checkboxes are enabled by default. So it's really a case of unchecking the rows which aren't required.
However, the DataGridView re-enables any checkbox that I click after I click on a checkbox in another row. So in effect, only one row can be unchecked at a time.
EDIT: I forgot to mention this is a Windows form, not an ASP.net application.
How can I get my textbox to automatically insert 'http://' before the url? It is an address bar in my web browser.
It needs to check if http:// is already there, and if it isn't, add it before the url.
I have a multi line textbox (in a windows form in vb.net application) that displays values from an array. What I would like is to have the height of the textbox increase automatically so that all the rows are visible in the textbox without the need to scroll down. Also I would like to know how this will affect any controls directly below the textbox in question. ie if the textbox grows in size, will it push the items below it further down or will it overlap them?

I am working on a LAN chat and I am having a problem. It's about the textbox that shows the conversation, it doesn't scroll down automatically, you have to do that manually. So is there something could make it scrolls down automatically? Something like showing the end or the bottom of the textbox.

View 7 RepliesI have two DataGridViews in one window. The first one displays 2 columns, itemNo and taskWhen I click on a row in this grid, I want to populate the second grid with corresponding material. It is organized so that the itemNo in grid1 is 1, 2, 3, and so on, and so when a row is clicked, I want grid2 to show data that is 1.0, 1.1, 1.2, 2.0, 2.1 and so on. This data is all available in a table that exists within a dataset. However, tableAdapters do not use the .StartsWith function. I am able to get the information from grid1 when it is clicked on using Me.DataGridView1.CurrentRow.Cells(0).Value.ToString but how can I use this to get the data from the table into grid2

View 14 Replieswhat I need to do is automatically (through a timer or similar method) look up a newly added record, and if it exists, have a number returned and populated to a specific textbox. I have the looking up the record and getting the field I want returned working fine, but I just cannot find any way to have it populate a textbox. Another small wrench in the works is that it's a web form. I think I'd be ok with a Windows form.The reason I need this is, the user will not be sure when this record has been added and it would work fine if they wanted to click a button until it is actually added to the table, retrieved and the number needed populates the textbox. However, the folks who gave me the spec prefer the user not to have to keep clicking a button for an undetermined amount of time. So, I've been trying to use a timer. I've tried everything I could think of to get it to populate the textbox. Even javascript didn't seem to work and neither did trying to a redirect back to itself. Everything is fine except for filling in the texbox.
View 8 RepliesI have a standard DataGridView. One of the columns is a DataGridViewComboBoxColumn. When I select one of the ComboBox items, I want to trap the change and add additional columns based on the item selected in the ComboBox. I've tried using CellValueChanged for the DataGridView column, and a bunch of other events, but none of them is fired when the DataGridViewComboBox value is changed. What event can I trap to make this happen? Right now as I said, I am using CellValueChanged, but of course the event doesn't fire until I click on another cell...

View 4 RepliesI have a textbox that represents a primary key in my database. Because the values are nvarchars I can't automatically increment for a new insert. Instead I have to read a value from a drop-down, perform some magic, and create a new incremented value for the new insert.
I've written codebehind that does all this when the drop-down is selected. It works, in that it puts correct values into the textbox. However when I try to insert, I get an error that that field cannot be null.
I'm pretty sure it's because I'm doing this in the codebehind : myTextBox.text = newValue
which wipes out the binding the textbox should have : Text='<%# Bind("UniqueName")
How can I calculate the needed value for this field programmatically and set it back to the screen so the user can see it (and possibly override it) and still keep the databinding intact so I can create the new record?

View 4 RepliesIve got a Listbox which displays a data/record from a SQL database, it displays "Amount" and only numbers would appear. it has a datasource.
Goal: I'd Like to get the total sum of those numbers from the Listbox and Display it to a textbox automatically or by button click event.
I thought of two ways to do this, but I don't have a clue on what to do.
1. I tried summing it all up on that exact Listbox and display the total on the textbox, here's the code that i came up with..
[CODE]...........
But the data im working with is from a database, so i got this error:Conversion from type 'DataRowView' to type 'Double' is not valid.
2. I thought of having another Listbox and "Copy" the contents shown on the Listbox1 and then sum it all up on the Listbox2, then lastly display the Total on the Textbox. I did a little research on how to accomplish that but all the clue i found is that i have to disconnect the listbox data from the datasource from being bound, and reconnect it again.. I really don't have any idea on how i could do that with an SQL database.
Here's a quick flow on what im trying to accomplish to make things.
Record from Database -----Displays on---> Listbox1 -----User Clicks--> Button1 ----Displays Total sum on----> Textbox1
