View 4 RepliesI am building a form in access database.
I have a combo box which is linked to a query which is looking up a unique reference number from a table called Tbl_Submitted_Requests.
What I need the form to do is auto populate the other text boxes when the user selects the unique reference from the combo box. How can I get the text boxes to auto populate with the data that is associated with each unique reference?
I would like to populate a drop down list using values from the database. I would like to know how I can add to the dropdown list both the display member and value member straight all from the database
Display Name: Account_Name
Member Value: Account_ID
Is there a way to populate the value in a dropdown? I am using the following command:
ComboBox1.Items.Add(DropDownData)
I have a GRIDVIEW with columns, one of which contains a CSV of possible values for the dropdown that must appear on each row.
Private Sub GridViewParameters_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridViewParameters.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow Then[code].....
Depending on whether the type of control is a dropdown, textbox, or check box (feined in the table) it hides or shows the relevant control type. If it is a dropdown it needs to get its values from a CSV in a corresponding column. I have a SP that returns a these in table form if passed the id of the relevant row.How do I get that is from the gridview to pass to the drop down and load it correctly?

View 1 RepliesI am trying to get my head around datasets, etc. The following code pulls data from an sql server and stores it in a data set. I then set the grid's datasoure to this data set. Now I want to populate a combo box on 'form load' with information from a field (surname) within the authors table.How do I approach this? I can do it in design mode but I want to do it in code as I feel you get a better understanding of what is happening under the hood.

I am trying to create a unit converter program. At the moment I'm trying to populate my combo box with results that have been calculated. I have two sets of results to display. I want them displayed side by side and have been trying very hard to do this. So far I've managed to get the result to display but only the original unit, it's start, increment and end value. Not the converted unit, start, increment and end value.
Then I managed to display both the original inputs and the converted inputs but they were showing directly below one another instead of being seperated into two seperate columns, i.e. original input, start, increment and end and the converted unit, start, increment etc.
This is the code snippet I am working with:
lstTableResult.Text = "" + (FormatNumber(lcInputValue, CInt(mdDecPlaces))), "" + (FormatNumber(lcResult, CInt(mdDecPlaces)))
The code above is incorrect and shows errors, i.e. is asking for end of statement.
The code below works, but it is only one code line, I've just split into two to make it work... not what I actually want.
lstTableResult.Items.Add(FormatNumber(lcInputValue, CInt(mdDecPlaces)))
lstTableResult.Items.Add(FormatNumber(lcResult, CInt(mdDecPlaces)))
I am using the following code for populating the combo boxes in my application. It is really nice. If any one requires, may use this. It takes three parameters. The first, the name of the Combo Box and the second, the SQL Statement to populate the combo box and the third is the number of column to be displayed (from the SQL statement)

Recently started working with VB.NET, and I'm just playing around with the controls and everything. What I want to do, is populate a drop-down list or a combobox (on program load) with data from a dictionary. I'm used to php, so I tried a for each dictionary.items as newitem combobox.items.add(newitem) but I can't get it working. Can someone give me an example of this? And what if i wanted only the key to show in the drop-down, and the corresponding value shown on a label besides it when I make a selection?

How to use a databound combo box to display one field in the drop down, and another as the combo box text on roll up? Using VS 2005... For example, I have a datatable that has 2 fields. One called "ShortDesc" and one called "LongDesc". I want to be able to see the "LongDesc" column values in the drop down on the combo box. When I make a selection, I want the text in the combo box to read the corresponding "ShortDesc" value.

My program handles XML files that have certain elements within a root-child node that are identical expect for their inner text value. So while populating my combo box with all of a root-child's child element's names I get like five identical items listed. Which brought about the problem of selecting say the third item and getting the value of the first displayed. So I came up with a loop function that determines if the selected combo box item is preceded by one of the same name, if it is, then it adds +1 to a counter variable and keeps checking farther and farther up the list. Once it loops to an item that doesn't have the same name it exits and it reads the Xth (X = counter mentioned earlier) element's inner text from the file. This works great for elements 1, 3, 4, and 5. But not for 2. A while back when I was focused on this problem I discovered the root of the problem but I was unable to circumvent it. I'll put the loop below so you can see the problem in action instead of trying to follow my verbose explanation:

The code works until it gets to the last item if there is only one item in the dropdown box it does not populate the text boxes, if I loop through the code it is going to the droplist index change but it goes from dr.Read() and just jumps to dr.close() without populating the text boxes?

I'm working in this application in Visual Basic Studio 2010 I have a combobox where user select phone model and textbox where a text file is loaded when user select model, I added text files to the project resource because I don't want to put them in files in the root directory of my application

what I need is a code to make text box load the text file wich have the same name of selected in combobox for example when user selct : CT-810 in combobox the text file with name: CT-810 must be loaded in the text box and so on for other combobox records
I have a combobox and have 10 items in it (Name of countries). I want to make the users life easy so that when they click inside the combobox and start writing then the text box will start predicting the rest of the text in the combo box. i.e. if i start writing "U" then the textbox will start predicting "UK" as "UK" is already a pre-populated item in the combobox.
How can I restrict the user from selecting only values within the pre-populated items of the combobox. Bearing in mind the combobox allows the user to write inside it (for the benefit of predictive text). But lets say there are values of UK, USA then I dont want the combobox to accept the value of "Ukraine" when the user clicks away from the combobox.
how to go about populating some text boxes with results from calculations. To be more specific, I'm trying to do some trig to calculate various parts of a ci0rcle and will be populating any two of the text boxes then click on a button to get the missing values. I was thinking along the lines of a loop until all values have been calculated.
