I have one drodownlist which show data based om textbox values...
Let us consider i have Select Name from table1 where Type IN(@typ) here @typ is textbox values here for example textbox will have some thing like this L1,L2,L3.. How to filter Name based and shown in drodownlist based on this L1,L2,L3(on textbox)..
I'm trying to bind a dataset (where the data is coming from a webservice) to a dropdownlist; the problem is that I'm getting duplicates in the list... how can I display distinct values only:
How do I bind data from an Excel file named Book1.xlsx in Column A to a dropdownlist? I've tried like this:
Code: connExcel.Open() cmdExcel.CommandText = "SELECT distinct BCName From [Sheet1$] where BCName <> '' and ProjectName like 'Total%';" oda.SelectCommand = cmdExcel oda.Fill(dt2) connExcel.Close() dropdown1.DataSource = dt2 dropdown1.DataBind()
But the dropdown is filled with "System.Data.DataRowView" for all the 5 lines in the dropdown. How do I get the values shown instead of this? It must be some formatting of dt2 I think.
I have a GridView control that has a SQLDataSource.
The GridView provides me with a list of musical artists (from the tblArtists)
In the Grid, I have a field, FKGenreID, that is a Foreign Key value for music Genres.
(An example of the data in that field would be "7", which upon lookup would mean Classical in the tblGenreList table.)
What I'd like to do is add a DropDownList control that looks up the tblGenreList table and populates the DropDownList with the ID and Description from the tblGenreList Lookup table.
Now the tricky part is that if the GridView field (FKGenreID) has a value, then I'd like the corresponding Genre Description to be displayed in the DropDownList
Alternately, if there is no value for FKGenreID in the GridView, then I'd like the DropDownList to show that nothing was selected, but have the list of Genres available.
Most importantly here, when the user makes a selection, I'd like the GenreID (from the DropDownList) to be entered into the FKGenreID field in the GridView field.
My thought is that a gridview record may or may not have a value in the FKGenreID field. Either way, the DropDownList is bound to that field. The DropDownList would display a list ofGenre Descriptions for the user to select from. Upon selection, the GenreID column of the DropDownList becomes the value in for the FKGenreID field in the GridView.
Is this possible?
In case it matters, I'm using ASP.NET 4, Visual Studio 2010, and coding in VB
I have a gridview with 3 nested dropdownlists in one cell on edit like this:To get the exact fields when the user clicks on edit I used the following code(yes it's messy)
[Code]....
The BLLOnderhoud is a class and the getReserveInfo is used to get the Model - Brand(merk) Information.Since the dropdownlists are nested in the gridview I can't call them directly and they can't call any of my functions.And this is the problem, when I change the dropdownfield Model the Auto field wich is the last dropdown(in the picture is a typo) should be binded like in the following code:
[Code]....
But the dropdownlist onDataBound event can't call any of my functions that are in my class.So my question is how can the onDataBound event of the second dropbox trigger a function? The only thing that the function has to do is to bind the 3rd dropdownlist
I m using the following code to bind dropdownlist using ADO.NET
Code: Protected Sub HeadsData() Dim conn As SqlConnection Dim cmd As SqlCommand Dim reader As SqlDataReader Dim constr As String = ConfigurationManager.ConnectionStrings("ams").ConnectionString conn = New SqlConnection(constr) cmd = New SqlCommand("Select HeadId,HeadName from Heads Order By HeadName", conn) conn.Open() reader = cmd.ExecuteReader() While reader.Read cmbType.DataSource = reader cmbType.DataTextField = "HeadName" cmbType.DataValueField = "HeadId" cmbType.DataBind() End While End Sub
I have 5 records in Heads table, but when i run the project it misses the first record and shows the remaining 4 in dropdownlist. Is there anything worng with this code ?
