Forms Data Controls :: Showing Read-only Data With Editable Data In FormView

Jan 4, 2010

I 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?

Forms Data Controls :: EditItem Template Of Gridview - Template Field With Dropdown List - How To Make Current Value Sel

Dec 4, 2010

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.

Make A SQL View Showing Data From 3 Tables Like Crosstab

Nov 18, 2010

I'm using 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 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]....

Forms Data Controls :: Showing Data From Multiple Tables In A Listview?

Jan 22, 2010

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.

Forms Data Controls :: GridView Control On Page Not Showing Current Data On Databind

Jan 29, 2010

I 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.

Aug 5, 2010

I 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.)


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.

Forms Data Controls :: Get Row Data In SelectedIndexChanged Handler For Dropdown Nested In GridView

Aug 2, 2010

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:


In the *.aspx.cs File:


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.)

Forms Data Controls :: Dropdown Doesn't Load With The Relevant Data When Select A Value From The First

Jun 10, 2010

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"
<asp:SqlDataSource ID="CostCentreDataSource" runat="server"
ConnectionString="<%&#36; ConnectionStrings:corkABCConnectionString %>"
SelectCommand="SELECT [CostCentreID], [CostCentre] FROM [CostCentres]">
<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"
<asp:SqlDataSource ID="ManagerDataSource" runat="server"
ConnectionString="<%&#36; ConnectionStrings:corkABCConnectionString %>"
SelectCommand="SELECT [EmployeeID], [EmployeeName] FROM [Employees] WHERE ([CostCentre] = @CostCentre)">
<asp:ControlParameter ControlID="DropDownList_CostCentres" Name="CostCentre"
PropertyName="SelectedValue" Type="String" />

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?
