View 2 RepliesHow do you use the http POST method with a Grid View on another page. I am trying to use the POST method to send the ID from the selected row of a Grid View, I am using a link button set to fire the select command and it has the Post Back URL set, from one page and then retrieve the ID value on another page using an Object Data Source. Also, under the Defining Parameters, I am setting the ID parameter to Form Parameter Source and have entered the Grid Views name in the Form Field.
View 4 RepliesIn order to support a legacy application that's in the field, I need my ASP.NET MVC app to return an empty response that also has a Content-Type. One of IIS, ASP.NET, or ASP.NET MVC is removing my Content-Type when I send back a null response. Is there any way around this? (While not requiring an empty response with a set Content-Type would obviously be the ideal solution, the clients are already out there, and many of them cannot be upgraded.)
EDIT: Since there was a request for code: I'm proxying the request from the new web application to the one that older clients rely on. To do this, I have a subclass of ActionResult, called LegacyResult, that you can simply return for those methods that need to be handled by the old software. This is the relevant part of its code:
public override void ExecuteResult(ControllerContext context)
{
using (var legacyResponse = GetLegacyResponse(context))
{
var clientResponse = context.HttpContext.Response;
clientResponse.Buffer = false;
clientResponse.ContentType = legacyResponse.ContentType; /* Yes, I checked that legacyResponse.ContentType is never string.IsNullOrEmpty */
if (legacyResponse.ContentLength >= 0) clientResponse.AddHeader("Content-Length", legacyResponse.ContentLength.ToString());
var legacyInput = legacyResponse.GetResponseStream();
using (var clientOutput = clientResponse.OutputStream)
{
var rgb = new byte[32768];
cb;
while ((cb = legacyInput.Read(rgb, 0, rgb.Length)) > 0)
{
clientOutput.Write(rgb, 0, cb);
}
clientOutput.Flush();
}
}
}
If legacyInput has data, then Content-Type is set appropriately. Otherwise, it's not. I can actually kluge the old backend to send an empty v. non-empty response for exactly the same request, and observe the difference in Fiddler.
EDIT 2: Poking around with Reflector reveals that, if headers have not been written at the time that HttpResponse.Flush is called, then Flush writes out the headers itself. The problem is that it only writes out a tiny subset of the headers. One of the missing ones is Content-Type. So it seems that, if I can force headers out to the stream, I can avoid this problem.
I am experiencing a problem on my aspx page.
I have a web form on which the user fills in a basic data: date (with drop down lists), an asset class (with a radioButtonList that is bound with en Enum) and other simple controls... The, when the form is submitted, I make a query on the database to retrieve my data and bind these data into a gridView.
Here are some bit of codes
protected void Page_Load(object sender, EventArgs e)
{
foreach (int assetclassVal in Enum.GetValues(typeof(AssetClass)))
{
[Code]....
The 1st time I submit the form everything is working well, the second time even if I change nothing in in the web form, the GridView1_RowCreated fires an exception when the property AssetClass is called. The error message is
Must specify valid information for parsing in the string.
This is because rblAssetClass.SelectedValue is empty, but I don't understand why.
I have this:
<asp:TextBox ID="tbxCustomer" runat="server" Font-Size="X-Small" Width="257px"></asp:TextBox>
<asp:CustomValidator ID="tbxCustomer_RequiredFieldValidator" runat="server" ClientValidationFunction="CheckRequiredField" ControlToValidate="tbxCustomer" EnableClientScript="true" ValidateEmptyText="true" />
So I want my javascript function fired even with empty text, but it doesn't. Is there a workaround or should just use jQuery to do this?
I added this code to the code behind but when there are not records nothing appears:
If GridView1.EmptyDataText = ""
Then
Response.Write(
"No Pending Records"
)
End If
If Pending.SelectedValue = "400" Then
Dim conn As New

I'm trying to set the default button to my master page for logging in.
Basically I've got a master page, with a LoginView in it, with a Login control in it, With a button in it... When you press "Enter" I want it to use that as the default button.
(structure in sudo-code if it helps)
BODY
Form ID=Form1
LoginView ID=MasterLoginView
AnonymousTemplate
Login ID=MainLogin
LayoutTemplate
Button ID=LoginButton
I know I've got to use .FindControl("") but as much as I mess with it I can't seem to get it to hook to the button.
When I Login the page using username and password and then click the logout button and after again click Login button without entering username and password it will be login,I want to show error
View 1 RepliesI have two web forms. One (Form1) with dropdownlist and button. Second (Form2) with the textbox , button and gridview.
I have the product list about 10000 items. When user go to Form1 and click the button. It will go to Form2 in which user will type the text in the textbox. And then click the button for filtering the productlist. the result will show in the gridview which will have select button in the first column.
When user select the product, Form2 will close and go back to Form1. The selected product will put in the dropdownlist in Form1.
How to do in the coding?
(1) Select button in the gridview with closing Form2, selected product put in the drop down list in Form1.
Is there one simple test that a person can do that covers all options where there could be a null, or "" value. When I google, I see so many options. I see:
if txtBox1.text IsNot nothing
if txtBox1.text.toString isNot nothing
if txtBox1.text <> ""
if txtBox1.text.toString <> ""
if isNull(txtBox1)
Is there on test that can cover them all?

fullname is a Label alright, but its Text property is an empty string. How do I get the actual string that is shown in the cell?
if i select a blank field and then insert to the drowdownlist in repeater.
how can i display the text of the blank field but the insert val is empty.
SQL as below:
select '' as Field_1 union select field_1 from table.
i would like to set the value to blank and display text to "please enter".
How to check the field value which is assigned to the text box is empty or not.
I need to set the visibility of the text box to false when the field value is empty.
My understanding is that the ErroMessage is supposed to be displayed in a ValidationSummary control. My page does not have a ValidationSummary and I set the RequiredValidator's Text property to empty. I expected that nothing would be displayed when the validated control is invalid, but the ErrorMessage shows up at the place where Text is supposed to be. I am wondering if this is normal.
BTW, ValidatorCalloutExtender is used. Is this a cause?
Now I have to set the Display property to None to avoid any displaying anything. This is not a big deal, but I am curious.
I am using ListView to display the Data.
I am getting some text or empty string from backend for a particular column.

I'm trying to execute a query and display the result in grid view.Its working well...
However,I wish to display some simple text like"No tuples selected" making gridview visible to false if there are no rows selected for that query executed.Is there a way to do that?
I have an aspx page which has 5 text controls as follow:
<asp:TextBox id="txtStudent1" runat="server" textmode="SingleLine"></asp:TextBox>
<asp:TextBox id="txtStudent2" runat="server" textmode="SingleLine"></asp:TextBox>
<asp:TextBox id="txtStudent3" runat="server" textmode="SingleLine"></asp:TextBox>
<asp:TextBox id="txtStudent4" runat="server" textmode="SingleLine"></asp:TextBox>
<asp:TextBox id="txtStudent5" runat="server" textmode="SingleLine"></asp:TextBox>
How can i set new text to each of these controls dynamically in .cs
WITHOUT explicitly doing something like this:
txtStudent1.text = "freshment";
txtStudent2.text = "Sophomore";
txtStudent3.text = "junior";
txtStudent4.text = "senior";
txtStudent5.text = "grad";
Can I use the for loop and increment the digit in the text control when setting its text?
ex:
For (int i=0; i<5; i++)
{
"txtStudent" + i .....
}
what can I use on a form that will hold images and text and can be sent as the body in an Email? For example, can I use a panel and add a table inside it and then organize text and images in the table and then use the panel as the body in the email?

I am trying to programmatically set some lables inside a DetailsView that is populated by an ObjectDataSource. The detailsview is handled in an unusual way with one TemplateField that has one ItemTemplate that has one table that has two rows of significance and a boatload of bound items. I'll be working on the EditTemplate next. But now I need to set the top row lable values programmatically baised on the type of data that comes-up. I have scoured the Internet looking for ideas and found two possible approaches - neither worked. I get the error about something not being set to an instance of the object - or something like that.
Here is the ObjectDataSource:

I have a GridView (inside an update panel) that has header text that changes based on some user profile information. I set the header text in the Page_Load function of the page - that works fine. The problem is that when I change to the page number of the GridView, the header text is not redrawn. I am handling the OnPageChanging event to try to update the header text but nothing is happening. I've attached the relevant code.
