Web Forms :: Finding Textbox Fields In Templates?
May 11, 2010
I have 2 textboxes that I am using for StartDate and EndDate in DateTime format, I am using DetailsView with Insert and Edit Templates, I was provided this code by "compguy2100", in order to make sure that the EndDate comes after the StartDate by at least 1 Minute. What I can't figure out is how to get the code to find the textboxes in question so it can validate them. I've used Detailsview.findcontrol with other controls however they are used with Item updating or inserting. I need this to run once the user has either entered a Date and Time and tabbed to a different dataentry cell. I've tried to use this code in the TextChanged event with no luck.
Dim StartDate As Date
Dim EndDate As Date
Dim Difference As TimeSpan
StartDate = CDate(txtStartDate.Text.ToString())
EndDate = CDate(txtEndDate.Text.ToString())
Difference = EndDate.Subtract(StartDate)
If Not Difference.Seconds >= 1 Then
lblDifference.Text = "Please make sure the end date is greater than the start date"
Return
End If

I have a Listview that is connected to an EntityDataSource. What I'm having trouble doing is showing fields of an association in the Item Template rather than just the id.
For example, what it currently shows:
Name: John Doe
Race: 3
What I wish it would show
Name: John Doe
Race: Caucasian
Some example code:
[Code]....
Obviously, I'm getting the number because Race_ID is an integer. What I'm less sure about is how to bind it or Eval it in some manner that will let me match that id to a name in the other table (which is associated). I've tried <%# Eval("Race.Name") %>' and a few other things to try to get a name rather than an ID but I always get either the id or nothing at all.

i am working on an asp.net mvc 2 web app and inside my model i would like to include a field named "" that has the values "Male" and "Female". I would like to use custom templates and Data Annotations in order to take advantage of model metadata. Specifically, i would like to create one DisplayTemplate (displaying the value) and one EditorTemplate (displaying a dropdown list) for the "Sex" type field.

I built an application where I use the ListView control to display data from my database. The user will be able to see a product image, product name, a dropdown list that contains various sizes of the product, a textbox and a button. All these controls are shown for each product from my database. The user is going to be able to select the size from dd-list and enter how many pieces he wants, and click the button. I wonder if there is someone out there who knows how I can check if the user has typed in the correct textbox. I have been using the findcontrol to find the correct textbox. But it turns out that it is not working properly. I want to verify if the user typed in the corresponding textbox, where he has chosen the size of the dd-Llista.
Here is what a bit of my code looks like now:

I have a gridview that have 5 columns. The first column is the select button, 2nd to the 4th are just displaying of data which I have used HTMLdecode to set it to disable the htmlencode so that I could display 2 lines in the gridview. However, after enabling htmldecode. my 2 fields, the select button and the text box columns are not able to be displayed out.
Here is the code for the gridview:
Protected Sub gvTransaction_RowDataBound1(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gvTransaction.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow Then
Dim cells As TableCellCollection = e.Row.Cells
' cells
For Each cell As TableCell In cells
cell.Text = Server.HtmlDecode(cell.Text)
Next
End If
End Sub

Is it need to use HttpWebRequest? how does it works? i want to pass data from a asp.net page's textbox to a textbox in a given URL/ a given website, how can i do it? For example, i want to pass a text box value which is entered by a user in my asp page, then the textbox value will be passed to the website's text box and get the response. I want to pass some data to a website-for example [URL] then call the submit button of the given website from my ASP.NET page, then get response from it. Â
Which means when user fill in the textbox in my asp.net page, Â [URL] the hotel search textbox will be auto fill in with the data (such as the date) that user typed in my ASP.NET page. and this will call the submit button of the website, so that the given website can response.

I have a GridView and a linqdatasource. The GridView is editable and when the user clicks to edit a row I want to concatenate two of the fields in the linqdatasource and place it in a single textbox.
I tried something like:
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("Field1") %> - <%# Bind("Field2") %>'></asp:TextBox>

I have a sql data souce that returns several columns of data, and they are displayed in a DetailsView on a pretty simple vb.net page. I'm stuggling with one field though for the details view.
It's a template field, and if ClientType=1 (this value is determined else where on the page), then the label in the template field should have Text='<%# Bind("ClientName") %>', but if the ClientType = 0, then the label in the template field should have Text='<%# Bind("ClientTemporaryName") %>'
How do I tell the details view to set the text for ClientName to one or the other?

I am using TempleteFields for all columns in my GridView. In that columns I am using only some fields for customization but not all.
Is there any performance issue with Databound Fields vs Templete Fields in a GridView...?
Do I need to replace the remaining columns with Databound Columns instead of TempletField columns...?
