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.

View 6 RepliesI 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.
ASPX

<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.
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.
I am using an asp.net autopostback enabled dropdown list. Here i want to restrict the autopostback property fot the value "Select" in the ddl. I have used javascript for this purpose. but not working.My code look like this.

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. What I have done is I have Amount as Templatefield and have set Autopostback = true. In the event handler for textChanged I have function for calculate Amount which will calculate the amount and set the calculated value in a textbox. But I am getting an error message:
[NullReferenceException: Object reference not set to an instance of an object.]
UpdateInvoice.calculateamt() +87

View 3 RepliesI have two textboxes insie an updatepanel, the same update panel also has a trigger from a Clear Button from the other update panel. The first Textbox AutoPostBack is set to true. The first time when the textchanged event is fired, everything work as expected--the labels got populated, the focus is set to the second textbox. However after I click on the Clear button, i entered something to the first Textbox, its TextChangedEvent fires--the labels got populate, the focus seems set correctly to the 2nd textbox, but I
cannot enter anything to the second TextBox. it seems like the form is not active--when i hit tab, I expect the focus move to next control, instead it moves to the URL box. Turn off the AutoPostback then put a button next to the first textbox will fix the problem, but I am wondering if there is other workaround to keep the AutoPostback of the 1st textbox?

I have an updatepanel with some textboxes and dropdownlists they have autopostback set to true. They are all defined as triggers on the updatepanel. I want the user to be able to change data in a textbox and tab to the next and have the text selected in each textbox he enters. My problem is I receive the first postback fine, make some database updates, then exit. The next textbox is not being selected, so I added thge final instruction in the data changed event to nexttextbox.focus. That seems to work, however the nexttextbox does not have the text selected. How can I do that?

When I place a value in TextBox1 and then click inside TextBox3 (which is there to have a place to go to get out of TextBox1 and TextBox2) the value from TextBox1 remains and is displayed in the MessageBox.Show correctly.
When I pick a value from the drop down calendar extender in TextBox2 for a brief micro-second the value from the calendar displays in TextBox2 and then the MessageBox.Show displays and the value in TextBox2 returns back to the orginally set value. The MessageBox.Show shows the orginally set value.
For TextBox2 if I set AutoPostBack=false then the TextBox2 works correctly and keeps the date picked from the calendar extender but the ontextchanged="TextBox2_TextChanged" never fires.

I have aproblem that when i add some special character in the textbox and submit the page it give error. A potentially dangerous Request.Form value was detected from the client (ctl00$ContentPlaceHolder1$txtname="<test>"). I found the solution of this porblem by ValidateRequest="false". But if i do this then the request will not be validate and then attacks probablity will be increase. what should i do to for this whithout using ValidateRequest attribute.
