Forms Data Controls :: How To Put Tooltip In Dropdownlist Bind With Sqldatasource
Mar 4, 2010
I have a dropdownlist that's being populated from a SQL datasource. I would also like to have a tooltip for each dropdownlist list item on mouse over. I found the example below which adds a title attribute for each list item using the listitem text as a tooltip but I want to make the title/tooltip value another field in the database. In other words,
item.Attributes.Add("title", someotherdatabasefield);
The end result would be something like this where the text for 'title' comes from the database
<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True">
<asp:ListItem Text="CompanyName1" Value="1" title="a really great company" />
<asp:ListItem Text="CompanyName2" Value="2" title="a really bad company" />
</asp:DropDownList>

SqlDataSource fd = new SqlDataSource();
fd.ConnectionString = "<%$ ConnectionStrings:ConnectionString %>";
fd.SelectCommand="select * from [Department]";
GridView1.DataSourceID = "fd";
it didnt work. And Gave the following Error
The DataSourceID of '' must be the ID of a control of type IDataSource...

I am using Visual Web Developer (VWD)and I dragged in i.e created a Gridview. In the codebehind of the page, I will like to declare an sqldatasource and get data from a database using the sqldatasource and then bind the sqldatasource to the Gridview. PS: I know how to drag-in an sqldatasource and attach it to the gridview using VWD but this time, I want to do this declaratively in the codebehind.

For example,
Dropdownlist contain 7 column name

Below is my current codes which I have a problem.
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)

SqlConnection conn = new SqlConnection("Data Source= EN\SQLEXPRESS;" + "Initial Catalog=ms;Integrated Security=SSPI");
SqlDataAdapter adapSel;
string mySQL = "SELECT '" + dd_list.SelectedValue+ "' FROM examtimetable ";
adapSel = new SqlDataAdapter(mySQL, conn);
conn.Open();
DataSet dsSel = new DataSet();
adapSel.Fill(dsSel);
GridView1.DataSource = dsSel;

SqlCommand sqlCmd = new SqlCommand("select column_name from information_schema.columns where table_name='examtimetable' and COLUMN_NAME not like '%ID'", conn);
conn.Open();
SqlDataReader ds;
ds = sqlCmd.ExecuteReader();
dd_list.Items.Clear();
dd_list.DataSource = ds;
dd_list.DataTextField = "Column_Name";
dd_list.DataValueField = "Column_Name";

I am facing a small issue in using a DropDownList that has only two values (AND and OR) which i want to use to configure a SQL Query in a SqlDataSource. How can i use this thing by passing the value in a SqlDataSource Select Query in such a way to Bind the Result to a GridView. I want something like this -
SELECT [somefields] FROM instinvoice WHERE Namen = @Namen @Option InvoiceNo = @invoiceno where @Namen is from a DropDownList and InvoiceNo is from a TextBox
I m having a problem in specifying this @Option parameter from a DropDownList which contains only two list items - AND and OR. On the Basis of the Selected Value from this DropDownList i want to execute query like
SELECT [somefields] FROM instinvoice WHERE Namen = @Namen AND InvoiceNo = @invoiceno
or
SELECT [somefields] FROM instinvoice WHERE Namen = @Namen OR InvoiceNo = @invoiceno
Using the Query with @Option gives me a Parsing Error. Why is that so. How can I implement this scenario.

I am trying to use a DropDownList in a DetailsView for the ItemTemplate, InsertItemTemplate, and EditItemTemplate. I must bind this DropDownList to a SQL-Server support table using a function that returns a DataTable. I am not allowed to use a SQLDataSource in my backwards IT department. So, not only do I need to load the DropDownList, I also need to make the SelectedValue equal to the current record that I am viewing, editing.

I have a series of dropdownlists on webform in ASP 4.0. The first drop down is filled upon load, and then when a user selects a value from that list, it populates the second dropdown. To accomplish this, I have a SQLdatasource with a parametersource of the first drop-down list control. This works great, except when a user changes their selection from the first drop down. It performs the query, but then adds the list of items to the ones that were already there from the previous selection, instead of replacing it with the new data. Here is the code:
[Code]....
Do I need to do something on selectedindexchanged to somehow "clear out" the previous datasource? I can't find anything about this online, although one person seemed to suggest it was related to using a master page. (which I am using).
