I would like to ask if it is possible to access data on a master FormView from a nested detail FormView.
I have a main form (master) with several tabs (detail) and would like to display a label with text from main form that is hidden by the tab at the moment of editting. My asp page looks like this.
[Code]....
Is it possible to get the value of the label CompanyTextLabel from CompanyTextBox using just ASP.NET expressions or something similar without writing c# code in .cs file?
I have a nested formview. I need to set a value for a textbox when I'm in insert mode from parent formview which is editmode.
View 4 RepliesI have a formview that use the formview iteminserted event. The information inserts into the formview fine, but all cells blank out after the insert. How can I make it so I can show all the values I have inserted show up in the formview after the inteminserted event?
View 2 RepliesI have a page with a FormView on it. The page is strictly for adding records to a Table. I have the FormView bound to an EntityDataSource and everything works greate except for one thing.
I want to initialize a date field in the FormView to today's date. So, in my page_load event I have:
if (!Page.IsPostBack)
{
//Initialize SetupDate to today.
TextBox setupdate = (TextBox)fvJob.FindControl("txtSetupDate");
setupdate.Text = DateTime.Now.ToShortDateString();
}
The first time this page loads, the txtSetupDate field is initialized.
Although, and subsequent loads of the page doesn't initialize the Text Box. I step through the code in the debugger and I can see that the code is executig, but something (the FormView bind?) is "clearing" the Text Box.
I'm attempting to load a GridView dynamically on a button is pressed.The gridview has AutoGenerateColumns="True" (set in skin definition) and has a declarative column definitions as follows:
<asp:GridView runat="server"
SkinID="GridViewDetail" ID="gvReport"
DataKeyNames="dateofcompletion">
<Columns>
[code]...
This all works fine the first time, but as soon as I select a different ddlCampaign item, it throws the"A field or property with the name 'FieldName' was not found on the selected data source" ERRORI kinda understand that it has retained the column mappings from the previous datasource assignment/binding and because the new datasource has different column headings it is throwing the error. What I can't seem to achieve is a clear or reset of defined gridview columns before adding the new columns. I cannot clear all columns because part of the GV defn is declarative.e.g.
gvReport.Columns.Clear();
gvReport.AutoGenerateColumns = true;
I have also tried clearing the previously added columns before new assignment/binding but it gives the same error.e.g.
for (int i = 2; i < gvReport.Columns.Count; i++)
{
gvReport.Columns.RemoveAt(i);
}
I am trying to bind the XML data to a datagrid from an XML file. I don't know why I am getting the message: "A field or property with the name 'User_x0020_Name' was not found on the selected data source."
The "User_x0020_Name" field does exist in the XML file. This is a portion of the XML file.

I am trying to reconstruct a date/time period from five data elements Year, StartMonth, StartDate, EndMonth, EndDate If the event starts on June 5 and ends on June 6, 2010 - The label would read June 5 thru 6, 2010. If the event starts on June 30 and ends on July 2, 2010 - the Label would read June 30 thru July 2, 2010. and if the event starts on June 5 and ends on June 5, 2010 - The label would read June 5, 2010. I've tried a few variations without success. This one comes closest to what I'm aiming for.

View 15 RepliesI have a dropdownlist that I'm binding to an objectdatasource within a edit template of a gridview. Everything works fine on our staging server, but when I view on our production server I get the following error:
"The type specified in the TypeName property of the ObjectDataSource 'ObjectDataSource2' could not be found."
The typename is correct. It works on our staging server. What would cause this to not work on our production server? Any way to re-write the code to get this to work? See the code below.

I have a dataview on a page. I am binding a list of Items, and each item has a Person object. So I get this exception "field not found in selected datasource" when I try to bind to any property on the person object.
[Code]....
It appears that the dataview is having problems with the person object because it will display all the properties for the Item correctly.
why I get a not found on the boundfield and not on the eval?
