I have a webform that the user inputs a date via a javascript popup calander, then it auto populates a textbox with 45 days after the inputed date.
My question is is there a way to have a postback once the input date loses focus. Here is my page.

When I write something to first textbox and press tab key to write something to second textbox, the second textbox don't be focused. I have to select second textbox with mouse to write something it.

View 6 RepliesI try to postback my page to the server using ctrl+Enter sequence.Without UpdatePanel it works well, but it works only two times inside updatepanel and then my control loses the focus. So I have some questions:
1. Why my control loses the focus if it is located inside updatepanel?
2. What is the best way to use ctrl+Enter sequence to post the page to the server?
Here is my code:

I noticed that with some of the data controls (like gridview and listview) the page loses focus when you click edit, update, etc. So if your data control is somewhere lower on your page, you'd have to scroll down to get to it again. Is this normal or is there a way to keep the focus or location on where you were previously?
View 2 RepliesI have a GridView that has approximately 800 records. I have a search feature that finds a record and focuses to it. When I click Edit for that record, the Gridview flashes and goes back to the 1st row. If I search for the record again it is in edit mode. Is there some setting to keep focus where it is? I added the following code to try and keep focus, but it doesn't work.

I have a form with several textboxes. All of these have AutoPostBack="True".
My problem is that the focus disappears to goodness knows where after each postback. The behaviour I would like to enforce is as follows,
If the user hits the Enter or Tab key after filling in a textbox then the focus should go to the next field on the form (to be explicitly specified in my code).
If the user clicks on textbox X after filling in textbox A then the focus should go to textbox X after postback, even if it is not the next in the list.
In other words, I want the form to behave in the way that most users would intuitively expect.
I have Googled for potential solutions to the loss of focus after postback but the few that I have found were many years old and I am unsure that the advice is still relevant for ASP.NET 4.0. Some of these old solutions also appeared to be invalid for browsers other than IE. What is the current best practice for handling this issue?
BTW, VB.NET solutions are preferred though I will also be happy to accept C# suggestions (which I would run through a code converter). Note that I have a single sub in my code for handling the TextChanged events for all my textboxes. This means that I have to use the following code to work with the textbox that has called the sub.
Dim CurrentTextBox
As
TextBox =
DirectCast(sender,
TextBox)
If addressing the focus problem means that I have to have individual TextChanged event subs for each textbox then so be it, but I prefer the simplicity of my current single sub approach.
I have a Gridview that provides the user the student name for a particular class, a dropdown list to enter grades. If a grade of 'U' is given, a textbox appears in which the last day of attendance must be listed.
It works... though not as conviently as it could; the faculty would like to be able to tab from one dropdownlist to next in succession.
On each ddlGrades changes I write the value to the database and if a 'U' was chosen, display the textBox... but I can't figure how to set focus on the next ddlGrades control, or even the same ddlGrades control that initiated the postbock.
Below is my simplified .aspx followed by the codebehind

I have a page that when auto or partial post back happens, focus is set to the address bar rather than the next control. The interesting thing is that when I put an alert in my RadScriptBlock, after the OK is clicked, focus goes to the correct control -or- if I put in an invalid location, focus is returned to the ExpLocation control & when a correct location is input the second time, the tab order/focus command works correctly (see code below).
That has this up top

Is there a way to have a textbox autopostback when the 5th character is entered into the textbox?
I have a zipcode textbox that I would like to fire an autopostback as soon as the 5th character is entered. Currently I have it so it will fire when tabbed out of or when the next textbox is clicked in but it would save one step for the customer if it fires on the fifth character.

<asp:TextBox ID="TxtDeptName" runat="server" class="formField"
Width="188px" AutoPostBack="True"></asp:TextBox>
<asp:Button ID="Save" runat="server" CssClass="ibutton" Text="Save"
Height="30px" Width="70px" />
The problem is, when i type something in Departmetn textbox, and click on the button, you have to click twice to get the actual results up. This is because the first click is doing the "AutoPostBack" part from the text box, and then you have to click again to make the actual click postback to happen.
There is button(btnOpen) and a textbox (txtResult) in the page.
Once I clicked on btnOpen, a modal dialog will appear, displaying TextBox1 and Button1.
The user is required to type something in TextBox1 and I want to pass the TextBox1.Text into my database but when I try to do that, the value actually = "", which is gone.
So I created this test program to illustrate by passing the value into a txtResult.
Can anyone guide me on getting the TextBox1.Text value?
Besides that, is there anyone to tell more about what does this lines of code do?

I used three textbox and one submit button,When that program run first two data enter
after cursor automatically move to button.
I have an gridview with 3 columns. As default I entered for each columnns an headertext, but depending on an language parameter in the data the headertext is changed on page_load with a SetLabels function.
Recently I added an templatefield textbox with an autopostback=true and an ontextchanged event :
When a user changes the text in the textbox all events are executed properly BUT my headertext is set back to the default value (from the .ascx) even tho page_load event is executing properly WITH the SETLABELS function.

In my gridview, I have a column for Amount. I want to calculate the amount as soon as user changes the Amount and display calculated Amount in a textfield.

[NullReferenceException: Object reference not set to an instance of an object.]
