I have a detailsView bounded by some other datasource. There is a dropdown in detailsview which is bounded by sqldatasource named "sdsNature" . Here is the templatefield for dropdown:
[Code]....
I want to show FNature instead of FNatureID in the selected mode as Label and in Edit mode as dropdown. When I am running this project, in Select mode it is showing FNatureID instead of FNature and if I click to Edit the record it is displaying following error:
'lstNature' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value Do I have to give some If else condition that if FNatureID is .... then dropdown should display FNature.... If yes then what should be the code?

I am using a dropdown inside gridview with sqldatasource but when iam executing this the output in simple colmun that is not showing dropdown list plz check my aspx code.
I think it is possible, what steps should I go through? And those videos all using Linq as data source, what if I have my own object data source and binding them in code behind, what about it?

View 6 RepliesI am displaying selectable rows in a gridview. The selected row uses a stored procedure to display all the fields in a formview when the Select button is clicked.
Only a small subset of the fields in the selected row are editable. When I click the Edit button only the EditItemTemplate fields show up, the read-only fields from the ItemTemplate disappear. I want the read-only rows to remain visible with the editable rows.
If I include the read-only fields in the EditItemTemplate, I get an error when I click Update on the FormView. The error states that there are too many parameters being passed to the stored procedure to update fields. How can I continue to show the read-only fields with the editable fields on the FormView and avoid getting the input parameter error on the stored procedure for the Update command?
I've currently got a form with two dropdown boxes on, and an XML file sitting on the site.
My two drop down boxes are Location and Date and what i'm trying to do it get the Location box to filter the XML and put the dates in the Date dropdown box.
I'm using C#.
Unfortunatly, its not working.
My code is:

and my XML is like this:

why my dropdown boxes are not being populated?
.I have a search page where I would search for an item and it would dispaly the results in a gridview...
I have allowed paging and set page size to 10..now I can see the 10 results in the first page and also see the page numbers at the bottom of gridview. But now when i click on the page 2, the method gridview_pageindexchanging is triggered but the result set is not dispalyed. My code is as below..
[code]....
i understand that the data is not binding in the GridView1_PageIndexChanging method..I do not know how can I make data bind..
Setting up the editItem template of a gridview. I have a template field with a dropdown list for editing. When the gridview goes into edit mode the dropdown list is displayed with all the right options but the current value of the field (pre-editing) is not the selected value of the dropdown list? How do I make that happen? I have a couple fields where the editItem template will use a dropdown list and I'm sure a user will not realize those values have changed and they will just edit what they intended to edit and save the changes, inadvertently also making changes to other fields.
View 3 RepliesI'm using ASP.net membership system with SQL Server 2000 database. What I want to do is create a view (or stored proc if that's better) which will return a table with the following columns:
UserName | Role1 | Role2 | Role3 | .... | Role*N*
Where the columns (besides Username) are generated to include all the ASP.net Roles in the application.I need this to be generic (i.e. when I add a new Role, I want the procedure/view to compensate and list that new Role as a new column). I want the values in the Role fields to be 1 (True) or 0 (false) if a user in in that role. I can make a table that has such columns using Dynamic SQL to create the variable number of columns, but I cannot seem to populate them.
How can I accomplish this?Tables involved are shown below:
CREATE TABLE [dbo].[aspnet_Users](
[ApplicationId] [uniqueidentifier] NOT NULL,
[UserId] [uniqueidentifier] NOT NULL, [code]....

I have a listview that shows the user the details of the members who have sent friendship request. The table from which the data come has two fields namely, sender_id[id of the one who sends friendship request] and receiver_id[id of the one to whom the request is sent].
There will be two columns in the listview. The first would show the pic and the name of the user. The problem is that how am I going to show the pic and the name if the table from where the data come does not contain these info. I know that the sender_id can be used to fetch the pic and name of the sender, but how should it be done?
Earlier I would do something like <%#Eval("fieldName")%>. But in the above described scenario the field is not present in the current table but the other one.
Say I have a table which as two fields Category and Subcategory. There are multiple sub categories under a particular category. when displaying in grid it shows all subcategories along with the category which is the same is this case.
How can I display records so that the category is displayed only once and all subcategories are displayed.

I just hit the same problem as described here: [URL] - GridView paging with ObjectDataSource. I see the column headers but no data, and I know for a fact my method returns a DataTable with data in it.
View 1 RepliesI have a page with a gridview control that shows files that have been uploaded to our site. The name of the uploaded files, who uploaded them, and if they have been downloaded, etc are stored in a table. The gridview is bound to the table through a sqlDataSource control. I have a button column in the gridview that downloads the file associated with a row when the button is clicked. All that works well. I have a check box column that shows checked if a file has been downloaded. When the download button is pressed.
the file downloads and then a short routine is run to update the downloaded field in the uploaded files table to set the downloaded field to true. This is done through a command string. All this works. Here is the question. After the update is run I do a databind on the gridview to update it. The databind is run in the PageLoad event is the page is a postback. This does not cause the current row to show downloaded =true (checked). If I refresh the page in the browser then it displays correctly.
in my page i have grid view and a add button which insert data in the grid view. when a new user (a) open that page and add few items in the grid view, then another user (b) open that page from another computer, the grid view is filled with the item those the user (a) added. but what i want, user will have the grid view with empty.
View 3 RepliesI have a Gridview here. My problem here is that my Gridview is not showing up any data after I clicked on the 2nd page and above. (Which means that my data is only showing up on the 1st page.)
[Code]....
Note: I'm using C# as my code behind. I don't have any code controlling the Gridview. I only have code to control the SelectCommand for my SQLDataSource.
I have a GridView, with a DropDownList as one of the Columns. I can get the SelectedIndexChanged method to trigger - but I cannot figure out how to get other Data regarding which row this triggered on i.e. if I could get the value in the ID column (DocID below), that would be great. My code is a bit too long, so I am just posting snippets. In the *.aspx file I have:
[Code]....
In the *.aspx.cs File:
[Code]....
I am wondering if I can get the DocID from within StatusDropDownList_SelectedIndexChanged - so that I can make appropriate changes to the Database. For e.g. in the RowDataBound event, which I had a GridViewRowEventArgs e, I could easily do e.Row.DataItem - to get the DataItem, I am wondering if I get/do something similar in the SelectedIndexChanged method. (I would prefer this be not the GridView Row Index i.e. I would prefer the DataItem if possible.)
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?
when i am selecting an item in dropdown list datasource is bind and after another selection it is bind again .but i want it bind only once.
