VS 2008 - Cant Find Drpdownlist In Formview EditItemTemplate Which Is In ModalPopup
Oct 22, 2010
I have a dropdownlist in my eidtItemTemplate of my formview which gets displayed in a modalpopup.
I try to get the ddl object like this:
Code:
Dim rateddl As DropDownList = CType(Me.fvTimeSheetDetail.FindControl("ddlRateType"), DropDownList)
but I get nothing. weirdly I can find a textbox like this:
Code:
CType(Me.fvTimeSheetDetail.FindControl("txtNewTSTimestamp"), TextBox).Text
howcome the ddl doesn't get detected? what am I doing wrong? the ddl is definitely there and it gets populated

I have a FormView and I want to set a default value from the database. I can't get it to bind to the value in the database. My FormView looks like this:
I have a formview on my aspx page containing various controls arranged using table. There is a DDL "cboClients" which i need to enable or disabled depending upon role within Edit mode.
The problem here is that i am not able to get that control using FindControl() method.
I have a Formview which contains a radiobuttonlist control in the EditItem template. I want to access the radiobuttonlist control and change the selected item client side using javascript.I've tried various combinations of document.getElemetByID and getElementsByName etc. but with no luck.Does anyone know to get to a radiobuttonlist controls in a FormView Edititem template using javascript?
I have a formview which binds to a table where one of the fields is an integer zip-code field. I want to pad the zip with a leading zero in the edit template when the zip is something like "02134". How do I edit the bound data without "breaking" the two-way binding?
I wrote simple function to add the zero and return a string:
Public Function padZIP(ByVal zip As Integer) As String Dim tmpStr As String = CType(zip, String) If tmpStr.Length = 4 Then tmpStr = "0" & tmpStr Return tmpStr End Function
How to write code in vb.net to control the Dropdown which is inside FormView EditItemTemplate. FormView named "frmFaultsReg" DetailsView named "lstStatus" Actually what i want to do that there is a textbox inside FormView EditItemTemplate and ItemTemplate to insert Closing date. lstStatus has a value PENDING and CLOSED. If a user select CLOSED from lstStatus then the date textbox named "ClrDateTimeTextBox" should show current date time and to insert into database and if user again selects PENDING from lstStatus then the date textbox should show empty. I think the postback of lstStatus should work but lstStatus is inside the FormView thats why I am unable to hook it.

The EditItemTemplate does not even load when I click the edit button on my FormView control, but I don't get an error message either.
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.

I have a dropdown list within a listview 'EditItemTemplate' and 'InsertItemTemplate" which I am trying to populate from the database with code behind with ItetmDataBound event. Problem is I am getting NullException when I use this code which works fine for ItemTemplate.
I have a gridview and it has two EditItemTemplates. I want to update the items inside the second dropdown (EditItemTemplate) when I select an item from the first dropdownlistbox (EditItemTemplate). I want to update dropdownlist2 when I select an item from dropdownlist1. How can I do this?
I have a Gridview Custom Control (class library project). What I want to do is, add a button to the page. Once the button is clicked, I need a ModalPopupEctender to come up with a checkboxlist of all the Columns in the SQLDataSource that populates the Gridview.
Now since this is a class library project that inherits from the Gridview, I'm not sure how I can add a div at the very top of the page, with the "Choose Columns" button.
Should I create a user control that contains my Custom Gridview? Reason I want to do what I ask is because I want to reuse this in as many projects as I can, I wan this functionality built in to my dll.
Below is a line I have in my ItemTemplate of a FormView. The value in the table is null rather than true/false. Is there any way I can set the default for this to be false if it is null? Or can I do this in my stored procedure in the Select statement to return false if null?

The user is getting a 500 internal error occurred. What he is trying to do is create a datagrid. The error only happens when there are a lot of data used to build the grid. But why exactly is it too much data? And can I increase a buffer or set something in a config file to allow all the data? The data come from a web service.
I am trying to update SQL 2008 to SQL 2008 R2 but it is asking me for my product key, which I don't know where its at. Is there a way to find it in the server, or something?
