Change Text In Combobox When User Changes Selection?
Aug 19, 2011
I have a combobox on a form with the dropdownstyle set to drop down. Users can either salect a value from the list, or type in any value they wish. This all works fine. However, when one particular item in the list is selected I wish to set a different value. Unfortunately I don't appear to be able to set the combobox Text property from within any of the events that fire when the selected item is changed.
I have two comboBoxes, one is CountryCombo and second is StateCombo.What I want is the that when i the clicks country combo and select a one country then the States of that the country should get populated in the State Combo.I have tried things many many many but nothing working. Below is my code of how my CountryCombo is getting filled.
query="select CountryName from CountryMaster" if dr.hasRows() {[code]......
I have a combo box that has multiple options, when the user selects one of the options (world wide city destinations) a specific value is assigned to a variable. For example if "New York" is selected the variable "x" is assigned the number 155. What I want to do is output the destination that has been selected ie "New York" in a label called "lblOutput1", do I need to store the destination as a seperate variable to be able to produce it in this label as I cannot seem to get it to work:
At the moment I am using:
lblOutput1.Text = "bla bla bla " + cmbDestination.SelectedText + " bla bla bla " + Today()
how can I make program using vb 2005 that will dropdown the datagridview combobox and display to the datagridview textbox everytime the combobox selection change or when you choose the data.The mousemove is not perfect because when the dropdown combobox length more than the datagridview, the mousemove will not work even other features of datagridview.
I'd like to force a user to make a selection from a combobox.I've tried to test it by Combobox.SelectedText = String.empty as well as another version similar to this but a little different.When I test it, it will tell me that it is still unselected/blank even when I selected something.
I have a combobox linked to a table Checklist (ID, Checklistname, and several multivalued fields). I want to have my subform display data from different tables based on my combobox selection "checklistname". All the tables are imported Excel files with the same fields and field types (ie. Discrepancy, reference, reference paragraph, category). How do I get my subform to requery based on the combobox selection? Or is there another method when working with "outside tables"? Import good/bad? Make new table? I have about 20 tables, if importing but only need particular data to save/store in my main table, and I need to know which table it came from.
On my DataGridView one of the columns is set to a ComboBox. When I make a selection from this ComboBox the CellValue change Event is not triggered. What event is triggered when I do the selection?
I have a calculate function that adds twenty text boxes together a+b, etc... 20 +20, B changes value when a selection in combobx is changed, how can i make the calculate funtion work up selection change in combobox ? You would think the selection change or index change , but that doesnt work because the tetbox doesnt actually get the new value till after the combo selection is made, so you actually have to go and make the selection twice I know i can put the code in the textbox value change , but i dont want to do that for 20 text boxes and i am assuming there must be a BETTER way?
I have just realised that ComboBoxes don't have a Change event. I have a combobox filled with a few items, eg. Bakery, Deli, Fruit & Veg, etc. Choose one of these items, all the related items show in the dgv. However, when I blank the text in the Combobox (press Delete key whilst Combobox has the focus), what event fires so I can blank the dgv? The combobox does not contain a Blank item. Even if it does, the Blank item only fires the ComboBox1_SelectedIndexChanged when the user scrolls down to, or clicks on, the blank value.
I want to clear the dgv when the user blanks the combobox without necessarily changing the selection index.
I have a completely basic program here that I want to simply take text from a textbox and the selection from a combobox, and then run the following:
CODE:
Obviously WKID and PROCESS are the variables it will be pulling from the data that was put in by the user. That code was just in a simple batch file that I made with 2 variables. I am wanting to pull those 2 variables in when clicking the "kill process" button, it will run a command simliar to the above and end a process on a remote networked computer.
I have a program that needs to display a playlist of songs, for a band performing someplace, from a .txt file. The songs in the file are listed as follows:
All You Need is Love-Beatles Rock 4.25
[code]....
The first line is the song's title and group name. The second is the songs genre. The third line is the songs length, 4.25 is 4 minutes and 25 seconds.upon clicking a button, I need to display a playlist from this .txt file based on the number of minutes the band has to play, minutes entered into a TextBox, and the songs genre, selected from a ComboBox. The songs cannot repeat and must be random.I have already coded the program to read the .txt file but have not clue where to start with the rest.
How Do I show the values from the dataset to the text box based on the selection from the combobox list i already populated the combobox my code is. [code]
title is a bit vague. Is there any way I can tell if it's the user or the code that's altered a combobox? I want certain things to happen when a combobox is updated, but I don't want them to happen when the code is altering the combobox at runtime, only when the user selects something out of them. Unfortunately, if I use the 'Selectedindexchanged' option that triggers when I change the contents in code too. I've tried disabled the combobox while I update it, but that doesn't seem to work. Any way to detect user input only? My combobox is drop-down only by the way, so it's only if they select an option - they can't type anything.
the below statment is right 100% but what i need is to change the word mobinil when the user choose another item from the combobox
cmd.CommandText = "select * from warehouse where mobinil ='" + ComboBox2.Text + "'".I thought that i can do the follwoing dim x as string x= here will be the item selected by user- and ofcourse i need it to be put instead of the word Mobinil cmd.CommandText =
"select * from warehouse where x value ='" + ComboBox2.Text + "'" is that possible ?
Is there a way to update source combobox to printer combobox selection?So going from printer1 to printer2 the source will update according to what that printer has to offer.
I'm having a problem with combo boxes. I usually use Java and it's been awhile since I used VB but I never remember having this much difficulty.My application is using an SDF file. From Data Sources, I drag the details on one of my Tables to my Form to get all of the fields. Three of them are comboboxes. Each of the three is an INT64 and each corresponds to a primary key in a different table. I click the tasks button on a combobox and for data source I select the appropriate table that has the data to go with the combobox, for display member I select the field that I want users to see, and for value member I select the primary key. Then I run a quick test and start the app, open the form, and add a new record. When I select a value from the combobox the selection won't validate because it doesn't think it's an INT64 like it should be. It seems to be using the display member as the actual value instead because if I change display member to the primary everything works great.
What I to do is really simple. I want to add a group of text boxes in my VB net application. note that the number of text box only can be known at run time.
I want to give default value to this group of text boxes. At run time, users can input text and change the text for each item.
How can I do this? Is there a control to do this?
What I can remember is ComboBox control. However, I only can display the item text and do not know how to change the text for each item.
I am currently working on a piece of code that allows the user to change the colour of some text in a text box. I have done the size and fonts fine but colour i am struggling on. I am using radio boxes to select the option. The code I used so far that works is this but how do I add the colour into it?
Private Sub radioArial_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles radioArial.CheckedChanged If radioArial.Checked = True Then[code]....
I currently have a form with two comboxes. The first cbo is being populated with a project number, which is being pulled from the first column of a spreadsheet. I now want the second cbo to read the first cbo and then find that project number on the spreadsheet; when it finds that project number, I then need it to copy data from the row the project number is on. I have converted to vb from vba. Below is the code I used in vba (which obviously does not work). I only need certain cells from the project row.
Dim proj_num, rng As Range Dim data, i As Long, j As Long With Sheet1
