Web Forms :: CustomValidator Not Fired With Empty Text?
Feb 1, 2010
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 have a C# 2008 asp.net form, and I need to call a function that will clear all text boxes on the page.
How can I go about doing that (the code for looping thru the textboxes on the webpage, and setting them to empty) ?

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

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?

In my .aspx page, I've a ValidationSummary where I put error messages returned by my Business Layer.
The error messages appears in the summary, ok, but not the "*" that normally appears next to the field =(
In the code behind, I've the following code:
CustomValidator cv = new CustomValidator();
cv.ControlToValidate = field.ID;
cv.ErrorMessage = "Error Message";
cv.Text = "*";
cv.IsValid = false;
Page.Validators.Add(cv);
Basically, I want to add the "*" next to each incorrect field, but without creating CustomValidators for each one... is it possible?

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.

In my current web application I have a listbox containing large number of elements. I have used an ajax listsearchextender to help the users in selecting the elements. I have set the autopostback property of listbox true. The application is working fine as expected in internet explorer. But in firefox while I am typing some text in search lable of listsearchextender the selectedIndexChanged event is fired and the page is posted back. So I am not able to selected the item properly using list search extender control. Can you please suggest me how can I stop the selectedIndexChanged event.

I have a about 6 or 7 text boxes which needs to be validated to make sure they are not empty from server side code. So how I usually do this is, check each textbox 1 by 1 to ensure that they are not empty. Are there any other efficient methods to do this? I have searched on SO and have found out that adding all the textboxes to a list and using a for each is a much better method. Are there any other ways that this can be achieved? Thanx a lot in advance :)

I am using c# with VS 2010 and dynamic data. I have a gridview that is populated by scaffolding. I then want to use the "Delete" command on the row. While the command works fine, it does not seem to know the datarecord has child tables in a one to many relationship, thus it wont properly delete the child tables before deleting the parent table. Which is fine, i can call some linq to sql to get the table id and delete all of its children before the parent table is deleted. Odd thing is, the Gridview is retruning "" emtpry strings for the cell that has the table uniqe ID.
[Code]....
and here is the gridview:

why i am getting a empty string for "GridView1.Rows[rowIndex].Cells[2].Text"?

I am building a Web Content form in which the user enters some data in asp:TextBoxes, and presses submit to store the data in the database.
I am using an Upadate Panel, in which I have put the afore mentioned asp:TextBoxes. Is there a way to set TextBox.Text = string.Empty after the submit?
Note that I have implemented code, which sets my TextBox.Text = string.Empty in my aspx.cs file, which of course does not work since I am using the update panel with an AsyncPostBackTrigger...

[Code]....
A breakpoint is set on FillForm() and this method is called two times but I can't explain myself why this happens. I have client side javascript code, when the form is being send, the onsubmit method is also called twice... Where do I have to search?! Is it a (known) bug? Think I could get it to work with this Thread: [URL] But why is the event fired within the onblur-event when it's fired anyway??
