Forms Data Controls :: FormView EditItemTemplate DropDownList Loaded From Codebehind Via Stored Procedure?

Sep 3, 2010

I'm attempting to load DropDownLists from the C# codebehind as the FormView switches modes to Edit and displays the EditItemTemplate. I present the data in a FormView ItemTemplate using text boxes. When the user selects Edit, I have been attempting to load the EditItemTemplate dropdownlists by creating a dataset and binding it to the control, without success.

I've successfully loaded them in previous projects from within the .aspx code using <asp:ListItem> and within the C# code behind using Control.Items.Add(new ListItem), which are essentially the same thing of course . This project is different in that I want to get the data from a stored procedure on a MSSQL server.

In my latest attempt, I can see the data in the datasets. I'm getting "Error connecting to database.'eitRace' has a SelectedValue which is invalid because it does not exist in the list of items.Parameter name: value"

I include the code below. If someone could point me to an example I would be greatful. There has to be an elegant way of accomplishing this.

Forms Data Controls :: How To Empty A Textbox In Detailsview Codebehind

Oct 27, 2010

I have a detailsview with three textboxes as itemtemplates. Each for holding a different date. To avoid the option of users entering invalid values the textboxes are disabled and the user can use a calender control to fill the dates. Because the textboxes are disabled I added a linkbutton to empty a date, if the user decides to clear it.

Asp:

[Code]....
In the code behind is the following for linkbutton on click:

Now, the problem is that no matter which linkbutton a user clicks all three textboxes are cleared/emptied. Why?

Forms Data Controls :: How To Move A Detailsview Sqldatasource To Codebehind

Apr 5, 2010

I have working code similar to the following in my Detailsview:

<asp:SqlDataSource ID="SqlDataSource3" runat="server" ConnectionString="<%$ ConnectionStrings:DATABASE %>"
SelectCommand="SELECT Id, PracticeId, FirstName, LastName, Notes FROM Providers WHERE Id=@Id"
UpdateCommand="UPDATE Providers SET
PracticeId = @PracticeId,
FirstName = @FirstName,
LastName = @LastName,
Notes = @Notes
WHERE Id = @Id"
InsertCommand="INSERT INTO Providers (
PracticeId, FirstName, LastName, Notes
) VALUES (
@PracticeId, @FirstName, @LastName, @Notes)">
<SelectParameters>
<asp:QueryStringParameter Name="Id" QueryStringField="Id" Type="String" />
</SelectParameters>
<UpdateParameters>
<asp:Parameter Name="Id" Type="Int32" />
<asp:Parameter Name="PracticeId" Type="Int32" />
<asp:Parameter Name="FirstName" Type="String" />
<asp:Parameter Name="LastName" Type="String" />
<asp:Parameter Name="Notes" Type="String" />
</UpdateParameters>
<DeleteParameters>
<asp:Parameter Name="Id" Type="Int32" />
</DeleteParameters>
</asp:SqlDataSource>

I would like to move all of this to codebehind so it's easier to work with programmatically. For instance the PracticeId is a selection from a dropdownlist that is populated from another table... i need to determine what the current selection is first so i can display the record / bind properly.

Forms Data Controls :: How To Disable Button Inside EditItemTemplate Inside DetailsView

Jan 20, 2011

I have a boolean / bit value in the database called "is_paid". Depending on this value I want to Disable a button. (the same would go for example to set a textbox not Visible, but anyway)

What I want is to Disable the button, if my boolean is 1 (true).

First I tried to convert my boolean value to text:

<asp:Button
ID="btnCalculatePayment"
runat="server"
Text="Submit"
onclick="btnCalculatePayment_Click" Enabled='<%#
Convert.ToBoolean(Eval("is_paid")) ? "False" : "True" %>'
/>

But got an error:

CS0030: Cannot convert type 'string' to 'bool'
However, if I use it one a Label it works fine: <asp:Label
ID="lblIsPaid"
runat="server"
Text='<%#
Convert.ToBoolean(Eval("is_paid")) ? "True" : "False" %>'></asp:Label>

So another trial I did was to CAST the data from the database to be the text that I want, like so:

SELECT not_paid = CASE WHEN is_paid = 0 THEN 'True' WHEN is_paid = 1 THEN 'False' END ....

And my code changed to:

<asp:Button
ID="btnCalculatePayment"
runat="server"
Text="Submit"
onclick="btnCalculatePayment_Click" Enabled='<%#
Bind("not_paid") %>'
/>

But got this error:

System.InvalidCastException was unhandled by user code
Message=Specified cast is not valid.
Source=App_Web_absjd3ob
StackTrace:
at ASP.manager_aspx.__DataBinding__control74(Object sender, EventArgs e) in c:Documents and SettingsAdminMy DocumentsVisual Studio 2010ProjectsWebManager.aspx:line 219
at System.Web.UI.Control.OnDataBinding(EventArgs e)
at System.Web.UI.Control.DataBind(Boolean raiseOnDataBinding)
at System.Web.UI.Control.DataBind()
at System.Web.UI.Control.DataBindChildren()

So I wonder, is it possible to change the "Enabled" property based on by boolean value?

Forms Data Controls :: Detailsview Mode Updates Read Only Field To Null Or Empty

Sep 10, 2010

I have a detailsview on my page binding a table with information about the employees. They can update their information. Some info should be visible but not updateable. I could change the update command not updating but I like the control where I can set the column to read only. In that way the employee will find the data visible and they will see that the field/column cannot be changed. But having the column read only will return a null-value into that column when editing and updating anything. Why is that? Shouldn't it just update it's read only value?

Forms Data Controls :: DetailsView - Binding Datafield To TextBox On Update?

Jun 29, 2010

I have a bound field in a DetailsView that I want updated with the contents of TextBox2.Text when I update. I have TextBox2 set AutoPostBack True. Cannot remember how to move the contents on update. I tried converting the "Description_Update" to a template field without success.

I can copy and paste the contents of TextBox2 into the DetailsView and it does update as do the other DataFields.

<asp:TextBox
ID="TextBox2"
runat="server"
Height="80px"
TextMode="MultiLine" Width="360px"
Font-Size="Small"
MaxLength="120"
Text=""
Font-Names="Calibri" AutoPostBack="True"></asp:TextBox>
<asp:BoundField
DataField="Description_Update"
HeaderText="Descrip"
SortExpression="Description_Update"
/>

Do I need to use adn Eval or DataBind function or both. I have triued several combinations and do nothing but continue to butcher the database tables.

Forms Data Controls :: DetailsView's ObjectDataSource Update Method Fails?

Jan 15, 2011

I am using a gridview to select a record and control that record using a details view. I am using a class based objectdatasource to link the data for select, update and delete. Sofar the select works but the update fails. Here is my error message:

ObjectDataSource 'odsDetailsView_1' could not find a non-generic method 'UpdateSet' that has parameters: setId, TYPE, iHPlayer, iAPlayer, iHRuns, iARuns, iH8Break, iA8Break, iHe8s8, iAe8s8, iH15BRn, iA15BRn, iHWins, iAWins, SET_ID, MATCH_FK, HOME_MEMBER_ID_FK, AWAY_MEMBER_ID_FK, HOME_TABLERUN, AWAY_TABLERUN, HOME_8BALLBREAK, AWAY_8BALLBREAK, HOME_E8S8, AWAY_E8S8, HOME_15BRN, AWAY_15BRN, HOME_TOTALWON, AWAY_TOTALWON, HOME_POINTS, AWAY_POINTS, LOCKED, GROUP_FK.

The first group of parameters have lower case letters and they come from my objectdatasources update method parameters. The second group of parameters are all capitalized and they are the fields in my SQL database table (and I don't know how they wound up in the error). This might be a clue.When executing the code my class method never gets the chance to execute because the error pops up before the code gets there.

Here is my objectdatasource:

Here is my detailsview:

Forms Data Controls :: How To Handle Blank Fields In DetailsView Update

Nov 18, 2010

I'm trying to use the DetailsView to make Updates. The problem is that it can't handle empty fields even though the underlying table field allows nulls.

I get a message like this if I change the "State" field to blank when doing an update

The parameterized query '(@Cust_ID int,@Cust_DL nvarchar(7),@DL_State nvarchar(2),@Last_N' expects the parameter '@State', which was not supplied.I'm using an object data source control which is calling the EditCustomer method in my Customer Class. I'm not sure how to fix this.
