Access :: Populating Database With DropDownList Data (vb)
Apr 30, 2010
I am trying to populate (store) an access database with the information from a DropDownList.
At the moment i have a form where the user inputs data into a textbox and on sumbission it adds to the access database. I am unsure how to add data to the database from the selections choosen in the DropDownList. I have a DropDownList for Title e.g. Mr,Mrs,Ms,Miss.
I have provided the code that populates the database from the TextBox's
Here is the code from a datagrid edit command in which I am attempting to populate a DropDownList in the EditTemplate from the database. The result is only one item (the first) from the database, instead of all items.
I have some field in datadase which is filled through checkboxlist , only selected checkbox has save to fields otherwise they remain blank: My problem is I want to show only filled value in label text using ";" , but when i am going to display it id display like:
Protected Sub gvPunches_RowEditing(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewEditEventArgs) Handles gvPunches.RowEditing Dim i As Integer = e.NewEditIndex() Dim ddl As DropDownList = CType(gvPunches.Rows(i).FindControl("ddlDiv"), DropDownList)
the question I have is when i enter this procedure in the code behind, ddl is nothing. what am I doing wrong in populating the dropdown for the row I am editing?
The Insert row in the ListView has an empty DropDownList and GetCountries() is not called. However, if I click the Edit button on an existing row, GetCountries() is called twice (not sure why) and the DropDownList is properly populated. Why isn't the InsertItemTemplate DropDownList getting populated?
On my formview I have a drop down list that is populated with the names of the files in a certain directory. This works fine, but when the drop down list selected value is bound to the database field I get the following error :
'ImageFileDropDownList' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value
I have setup other drop down lists in the same formview populated from SqlDataSources and these all work fine. I can see perhaps why this is an issue because I have not specified a DataValueField or a DataTextField for this drop down that is populated in code (whereas I can for the SQL bound ones) because I'm not sure what these settings would be.
I need to have a "blank" option as well so that the field does not default to the first value in the list.
My code (I have stripped out some meaningless controls) :
1. textbox (Search for staff) 2. Dropdownlist( Search for department) 3. Listbox( Populate staff name based on textbox or dropdownlist)
I am able to populate the staffs indenpendantly according to what is written in textbox or dropdownlist. Whar i wanted to do is mix the population of staffnames from textbox and dropdownlist. In other words, when i search "sandra' in textbox and select a Department A , the listbox will show all the sandra from Department A only.
I have a ListView that I need to populate a dropdownlist while rendering. For each rown in my table has a field called sizes which has data that looks like this "blue; red; yellow; green", I need to render a dropdownlist in the ItemTemplate with these values, I tried placing a PlaceHolder but I don't know how to populate it. I have tried to populate it OnItemDataBound and OnUnload but neither seem to work.
I read your article on ASPSnippets and everything worked great. I am having one problem and this is preventing me from moving forward. When I select the edit for a row (I only have two columns), the drop down comes back blank (no records). I have looked at the code multiple times and can't see where I made a mistake. is it possible to control the width of the drop down list? I can't tell if the column automatically adjusts because I am not returning any records.
using System; using System.Collections.Generic; using System.Linq;
during edit mode i populate the drop down in question with data based on a value selected in another drop down also in the gridview, all works find, but the paramater is not being updated with the selected value, i think this is because i do not call any Bind in the aspx side.
I am making an application that deals with vehicles. I need two DropDownLists:
Makes: All Vehicle Makes Models: Models that belong to the selected value of the Make DropDownList
How is this done in MVC2? My Idea: Do I use an ajax call when my first list is selected and then pull back the Models to bind to the Model DDL? How would model binding come into play that way? UPDATE I posted what I ended up doing as an answer. It is super simple and works great. You can use a get too if you feel so inclined, but you have to specify that you want to like so... return Json(citiesList, JsonRequestBehavior.AllowGet);
I am drawing a blank and need some direction.I am putting together a simple website that has a single DropDownList that is DataBound to table inside of a FormView Template.What I want to happen is when the page loads, it runs the SELECT statement and displays that result(which it does, so that part works).Where I am stuck is that if I Click the DropDownList and select another item, and display the results of that selected item in the associated Databound controls.My code is below;
I have a dropdownlist in EditItemTemplate and InsertItemTemplate which I want it to populate at the runtime while Inserting an item or Editing an item.
I am facing an issue regarding populating a dropdownlist dynamically while in Edit and Insert mode. There are 0 Records in my table and it shows "Empty Data message" in my Listview control. Even the ItemDataBound event does not fire. So I am not able to find the dropdownlist in that listview.
This is my Aspx code which shows only InsertItemTemplate and EditItemTemplate.
I need to create a TemplateField column dynamically , which will contain dropdowlist controls. I've been using this example to create my first dynamic columns and for the last column, the one that contains dropdowlist controls, I've written this class:
[Code]....
But what I don't know is, where should I populate the dropdownlist control?
I have one table which contains branch codes(primary key), Branch name and bank name columns. I have 3 dropdownlist boxes. the first dropdownlist is for the branch codes. When i select the a branch code i need the second dropdownlist box to populate with the appropriate branch name and the third dropdownlist box to populate the bank name at the same time.
Is it possible to have one table like mine and acheive this, if so how do i go about doing this?
I did read up on this but only came across ones with 3 tables.
I'm not sure if I can explain this properly, I just need some advise. I'm working with a formview and datasets to populate the information. However I have a table specifiying which fields to display. In my table If cell, work and home fields are selected then those fields must be populated in the formview if they not selected then it shouldn't be shown. These are 2 different datasets being pulled into the formview.
Right now I have a datasource populating the formview via the wizard, not sure what to do next.
Okay, I have developed VB.NET winforms applications and I understand that working with ASP.NET would be similar. However, this seems way complicated then I thought. Basically, i am working on accessing one table data from a database and populating data in a datagrid. I have few text boxes on the display page and if a user clicks on submit button i want a new set of data with new select statement based on user input.
I don't quite understand how the textbox value can be passed on the same page and a new select statement is generated, which then populates the datagrid.
When the FormView is in Edit mode, ddlCategory is populated as expected by calling GetCategories(), which returns a List of categories. However, when the ListView is in Insert mode, ddlCountry is empty. I put a break point in GetCountries(), but it never gets called. If I change the name of the method, I get an error. So it recognizes the method at compile time, but does not call it at run time. I'm guessing this is an embedded binding issue of some kind, but I'm hoping someone can save me a lot of time by pointing out the solution.
I am getting a problem while working with the Dropdownlist in VS2008. I am trying to populate the DDL using c# codding instead of creating DataSource in GUI. The DDL is getting populated as expected, but then I've added a label that will show the current selected item; for this I've written a code in DropDownList1_SelectedIndexChanged() :
I hae also enable AutoPostback for the DDL. I have placed the PopulateDDL() method inside of the Page_Load(); But whenever I select a item, it's always giving only the first item's name as the Lebel.Text. But when I use GUI and ceate a SqlDataSource and attach that to the DDL all works fine. What to do??
I'm new to MVC pattern and I have a question regarding to a dropdownlist. Actually My Data came from a collection (random string) then it displays it in a list. And yes it display, so I add a dropdownlist. And I can populate it using the same collection. My question is how can I populate the dropdownlist from different collection?
so I am having an issue getting a drop down list to choose the right value when it renders. It always defaults to index zero. However, I do have a view in another place where it renders just fine and selects the right value. I don't understand the difference.
Here is a trimmed down version of the view that works correctly:
@model AppName.Models.Guest @using (Html.BeginForm()) { Attending Ceremony?<br /> @Html.DropDownListFor(x => x.ConfirmCeremony, new SelectList(new Dictionary<string, string> { {"No Answer", "No Answer"},
