Forms Data Controls :: How To Load DropDown On The Basis Of UserProfile
Mar 4, 2010
I required to load dropdown with the section name on the basis of UserProfile when the page load anytime.
The dropdown is bounded by sqldatasource configured to TblSections.
TblSections with datafields sectionId(numeric) and Description.
There is another table Users with field sectionId and UProfile.
There is a gridview grvResult bounded by objecdatasource configured to TblFltReg.
TblFltReg has field Owner(numeric).
Actually Owner and SectionId are same.
I don't know how to do this task.

I have dropdown and I have to bind that dropdown on the basis of user login so that when the page load the drop down should show only one item on the basis of user login and i may have use that dropdown item as a search parameter.I have a objectdatasource named TblFltReg having one of the fields named "Owner" which is the SectionId.
There is a table named TblSections having "SectionId" and "Description".User can be selected in a Session variable.I have another table "Users" having "UserName", "UProfile", "SectionId".Actually I dont know how can I get SectionId from Users table into Session variable.So I have two tasks: one to get SectionId into Session Variable and another is to show dropdown item on the basis of User login.Hope you understand.
How can I perform that task?

I have a dropdown menu with too many items bounded by sqldatasource.
I want to show only those records which matches the Session("UserName) so that if user login to the webpage he may be able to see only those records that are related to him and further if he selects it then data should populate to gridview.

For insertion, I have dropdown inside a form.
The dropdown is linked with sqldatasource which is retreiving distinct records from table.
In table there is no NULL value.
What I want to do that when user will access Insert page to insert record then like all textboxes, dropdown should also load with NULL value.

I am experimenting with 3 dropdowns bound to 3 different datasources. I want the contents in each dropdown depending on what is selected from the above dropdown and the datasource queries reflect this.
<asp:DropDownList ID="DropDownList_CostCentres" runat="server" Height="16px"
Width="138px" DataSourceID="CostCentreDataSource" DataTextField="CostCentre"
DataValueField="CostCentreID">
</asp:DropDownList>
<asp:SqlDataSource ID="CostCentreDataSource" runat="server"
ConnectionString="<%$ ConnectionStrings:corkABCConnectionString %>"
SelectCommand="SELECT [CostCentreID], [CostCentre] FROM [CostCentres]">
</asp:SqlDataSource>
<br />
<br />
<asp:Label ID="Label2" runat="server" Text="Manager:" Font-Bold="True"></asp:Label>
<br />
<asp:DropDownList ID="DropDownList_Managers" runat="server" Height="16px"
Width="138px" DataSourceID="ManagerDataSource" DataTextField="EmployeeName"
DataValueField="EmployeeID">
</asp:DropDownList>
<asp:SqlDataSource ID="ManagerDataSource" runat="server"
ConnectionString="<%$ ConnectionStrings:corkABCConnectionString %>"
SelectCommand="SELECT [EmployeeID], [EmployeeName] FROM [Employees] WHERE ([CostCentre] = @CostCentre)">
<SelectParameters>
<asp:ControlParameter ControlID="DropDownList_CostCentres" Name="CostCentre"
PropertyName="SelectedValue" Type="String" />
</SelectParameters>
</asp:SqlDataSource>
However, the second dropdown does not load with the relevant data when I select a value from the first dropdown (stays blank). Must I still provide an event handler and how do I combine this with the sqldatasource?

I am looking for a way to set certain cells in a GridView to have DropdownLists instead of the bound fields I currently use. I understand how people are able to do this on a whole column, but need to do this based on which cell it. Let me explain why. A fellow programmer who is as I am newer to ASP, built a GridView that only shows one record. This Record being the current ticket if you will. He builds a Data Table like this.

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.

I have a page with 14 dropdown lists. In the first page load (ie. not isPostback) I set the selectedIndex of the dropdownlists individually but I find that they are all set to the value I use for the last dropdownlist set. Here is the code
comboFirstJudge1.SelectedIndex = 0
comboFirstJudge2.SelectedIndex = 0
<so on for all the dropdown lists until the last one>
comboFirstJudge14.SelectedIndex = 4
The result is that all dropdown lists have SelectedIndex = 4. If I run the same code on a postback it works just fine (the first lists have SelectedIndex = 0 and the last one = 4).

I've noticed that page load time increases dramatically as you load up a ddlistbox with items. 10,000 or so results in a pretty much unacceptable wait time for my setup. The dropdown I'm trying to load is Airports - like all of them. What are some alternative UI solutions that give the user the ability to easily select any (literally) airport, but without a ginormous page loading time? (Currently the dd is keyed to the airport's 3 letter code, so it's convenient for the prepared user to just type the 3-letter code and have the right airport selected. The display is then set to code, city, country.)

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]....
Till here it works fine how do I fill the dropdown from database.Eg Active text is coming from Database,so DDL should show Active along with Inactive value.
