Forms Data Controls :: Searching Database By A Dropdown List AND Text Box
Aug 10, 2010
I am very new to coding in asp.net, I've never done anything before, but heres my problem, I have a Microsoft SQL Server 2005 Database, and basically I need to be able to search that database by 3 different things, basically there is tons of data, and I need to be able to search by a member ID, a location, and a group name So basically I wanted a drop down list, with these 3 column names, and than a search box where you can actually type in what you are looking for, than have the results display, I have been trying to do this with gridview, but I can't seem to get it to work correctly

I am stuck at this point "Displaying a dropdown list of Categories with a --None -- Option. I want the gridview control to display 2 dropdown list one in read-only mode and the other in edit mode. When a record is in read-only mode, the dropdownlist's enabled property will be set to false."When it's on a read-only mode, it doesn't display the selected Category. it shows but the "No Category". When i click on edit to edit or change category, it doesn't display the selected category.
The example is given below( I am reading the book Sams Teach yourself ASP.NET 2.0 by Scott Mitchell. page 628)

I'm building a small website using ASP.net/C# and I wanted to know how to implement a simple search feature using a text box and a dropdown.
The datasource is a products table and in the text box I enter the product's name and in the dropdown are the categories. (I have managed to populate the dropdown with the available categories already)
It must follow these conditions:
If both text box and dropdown are blank all products must be listed;
If a category is chosen all products from that category must be listed;
If only text is filled, all products that match are shown;

On my website, registered users can make a profile about themselves suchas name, Favoirite color, hobbies, etcI have a DataTable called User which hold this information.also there are other datatables for Hobbies and Colors which list all possible options.To let the user update their choices I have a FormView in Edit mode on the aspx page whichis binded to the UserTable with a GetProfileByUserId Method and objectdatasource.
Within the formview, i have added drop down lists that are binded to the hobbies and Colors tables so they can edit their previous selection.On clicking Uodate update formview calls an Update Method that adds new selections to the User databaseNow I have two questionsIs it possible to show in the dropdown list the selected value that the User has already made?If the user only changes hobbies and not colors when they click update will a null value be passed into the data table for colors that replaces their previous selection?

I have a databound dropdownlist and have a problem with the default value it selects.When I attempt to edit a record the dropdownlist shows the first value in the list rather than the current value. I want the dropdown list to display the current value.
I'm sure this is very simple but I'm very new to ASP.NET.
I'm using .NET version 4.

First, a user select a country from a dropdown list. The selected item & its value are store in a seesion. Then the user leaves this page.
<asp:DropDownList ID="ddl1" runat="server">
<asp:ListItem Value="US" Selected="True">USA</asp:ListItem>
<asp:ListItem Value="AF">Afghanistan</asp:ListItem>
<asp:ListItem Value="AL">Albania</asp:ListItem>
</asp:DropDownList>
Dim arr(1) as string
arr(0) = ddl1.SelectedItem.ToString
arr(1) = ddl1.SelectedValue
Session("arr") = arr
Later on, the user may come back to the page and change the selection of the country. However, I want the dropdown list to remember the previously selected item and value. The item name and its value are now stored in an array. How do you assign it to the dropdown list as pre-selected.

I have several dropdown boxes. After user selecting those drop down box, I will insert those values to the database table.
Here is my code:
string InsertString = @"insert into Table..user(PID, GID, TID, SID, SSID) values ('DropDownList_PID.Text', 'DropDownList_GID.Text', 'DropDownList_tid.Text', 'DropDownList_sid.Text', 'DropDownList_ssid.Text')";
OleDbCommand myCommand = new OleDbCommand(InsertString);
myCommand.Connection = myConnection;
myConnection.Open();
myCommand .ExecuteNonQuery();
I always got the error.
OleDbException (0x80040e57): The statement has been terminated. String or binary data would be truncated.] System.Data.OleDb.OleDbCommand.ExecuteReaderInternal(CommandBehavior behavior, String method) +745 System.Data.OleDb.OleDbCommand.ExecuteNonQuery() +113

I will try to keep the question short:
1. I am new to ASP and I can not get this to work:
2. I am Using a <asp:DropDownList in a <InsertItemTemplate> in a <asp:ListView
3. The dropdownlist during insert does not get polulated (it is empty) while the same construction and same datasource works in the edittemplate: <asp:DropDownList in a <EditTemplate> in a <asp:ListView
4. I noticed that filling the dropdownlist with a <asp:ListItem works; the insert list is populated. (not usable for me) In both cases I use the same datasource from the code behind like this : Edit:
<asp:DropDownList ID="DropDownStartday" runat="server" SelectedValue='<%# Bind("startday") %>'
DataSource="<%# GetDataSourceStartDay() %>" DataValueField="daynum" DataTextField="dayname"
Insert: (with or without Selectedvalue: NoJoy)
<asp:DropDownList ID="DropDownStartday" runat="server"
DataSource="<%# GetDataSourceStartDay() %>" DataValueField="daynum" DataTextField="dayname"

I want to display the selected value from gridview in a dropdownlist.Here I am not getting the Dropdown from Database as it contains two values.After getting the data user can modify the DDL and change the selection.The data type where the values are saved is declared as Bit.
<asp:Label ID="lblQuery" CssClass="labelbold" runat="server" Text="Query"></asp:Label>
<asp:TextBox ID="txtQuery" runat="server"></asp:TextBox>
<asp:Label ID="lblStatus" CssClass="labelbold" runat="server" Text="Active Status"></asp:Label>
<asp:DropDownList ID="ddlStatus" runat="server">
<asp:ListItem>--Select--</asp:ListItem>
[code]....

Can these two properties of a dropdown list in ASP.NET be used independently?
I wanted to retrieve a null value when the user selects some text; I couldn't as it retrieves the Text property whenever the Value is null. Eg:
l1 = new ListItem("Cat", null);
Console.WriteLine(l1.Value);
The output is
Cat
In another situation, when both the properties have different strings, I get the string in the Value property when I use the Text property. Eg:
l2 = new ListItem("Cat", "Mouse");
DropDownList ddl = new DropDownList();
ddl.Items.Add(li);
ddl.SelectedIndex = 0;
Console.WriteLine(ddl.SelectedValue);
Console.WriteLine(ddl.Text);
The output is
Mouse
