I have a timer control on my gridview that refreshes it at a 3 minute interval, but when a user is updating the gridview it will mess us the update and then they have to start over again. How can i set some kind of focus event on the gridview to shut off the timer update that refreshes the gridview.
View 2 RepliesVS2010 ( Vb.net ).I have a masterpage that contains a gridview, giving stats and information on client files sent to us. This gridview is updated by means of a timer control every 10 seconds. In my grid I have an image field, to display either a tick .. if everything is ok or a cross for any problems.When the timer control timer event forces a gridview databind every 10 seconds.When the page first loads, i get the default red Cross in the gridview imagefield, however when the timer loops forces a 'databind' I lose the redCross and it is replaced with the default image control ( as if no url is set ) . Then I get a server 404 error.I am using the OnDataBound event to fire my vb sub. I have commented out evertything just to get a solid starting point but im still getting errors.

I have a Gridview and I allow fullscreen editing. I have some RequiredFieldValidators in my Gridview and this works fine. But if the user clicks on a dropdownlist in the Gridview and chooses "Rejected", I want to turn off validation. But I am not sure how to do this. Here is my code in the SelectedIndexChanged event for the ddl:
Protected Sub ddlPOACKCodes_SelectedIndexChanged(ByVal
sender As
Object,
ByVal e
As System.EventArgs)
[Code].....
But I get an error on this line: rfv = gvPODetail.SelectedRow.FindControl("rfv11"). the error is:
Object reference not set to an instance of an object.
I have an updatepanel in my content page with a timer which re-renders the updatepanel every 5 seconds.I also have a textbox outside of this updatepanel in my masterpage.Whenever the timer ticks, focus is lost from my textbox. What possible reasons are there for this happening?
View 19 Repliesi have three textboxes in a page and one datagird and 1 timer control, i have 2 update panels.
i placed (all textboxes) in one update panel and i placed (data gird and timer control) in an other update panel, because i want to reset or clear all fields when cancel button is clicked so that update panel should be updated,and where timer control tick event is fired i rebind the gird or refresh the gird, i have done this and it works properly but problem is that when i am going to write some text in any textbox or i want to focus on any text box it should lost focus when timer control tick event is fired so how can i maintain focus, or even how can i get focus of current control and after firing of timer control tick event i should reassing focus of such control
my code is below

On the home page of my site I have an UpdatePanel with a Timer which ticks every couple of seconds. Un-related to that I have a user login forum (username / password) If you are typing your username into the textbox while the timer ticks, it takes focus off the textbox.
View 9 RepliesI have some code where I need two separate required field validators for one control, both in separate validation groups which are then validated by two separate buttons.This approach works well when the buttons are clicked but both validators show if I enter a value in the textbox and then remove it.
Is there a way to turn this"lost focus" validation off? I only need it to validate when the buttons are clicked.
EDIT,Unfortunately, if I set EnableClientScript=false then I dont have any client notifications. What I want is for the dynamic error message to show (effectivly in the OnClientClick event of the button) but not the "lost focus" of the textbox.Is there some way I can disable or "unhook" the lostfocus client event?
EDIT,A combination dDejan's answer and womp's answeer here sorted the problem perfectly.
My final code looks like this (for anyone else with a similar situation)...
Javascript...
<script type="text/javascript">
$(document).ready(function() { [code]....
So, now there is no validation until a user clicks either the "Get Email Confirmation Code" button or the "Register" button. If they click the "Get Email Confirmation Code" button all of the controls validate apart from the textbox where the user is to input the email validation code and we only see one validator message.
If they click the "Register" Button then all of the controls validate and we only see one validation message.If either button is pressed, the user goes back, adds and then removes some text then we only see one validator. Before this change you used to see both messages saying the same thing.
I am trying to set the focus to a control in a gridview (QTY).
<asp:TemplateField HeaderText="Quantity Needed">

I need to set the focus on the QTY control in the next row in check_qty. I was able to set the focus on the control in the current row by using:
row.FindControl("QTY").Focus()
but I need to set it on QTY in the next row.

I am updating a gridview. Problem is that when I hide certain fields that I do not want the user to update, they lose their values ie. the data is wiped out in the field unless I show them on the grid and make them writeable. Is there a property I need to set for the field to retain the value when the grid is updated or is this in the sql statement?

Here upon loading the page there will be 4 panels having their own timer controls (having interval 1000) for incrementing a variable "a". But the problem is that, as I have used static variable that's why all the timer's are sharing the variable "a" and creating a problem like each panel's label showing a value incremented by 4 after every second. Can any body solve this problem..

VWD 2008 Express. Visual Basic. I have a gridview that displays the grade records of students in a class. I am only able to select one row at a time to edit (using the "Edit" button for that row, followed by "Update" when I am finished. I would like to turn on edit for all rows at the same time or for a group of rows and then have one "Update" button to press when I am done with all editing, much as in a spreadsheet where you are not restricted to a single row before you press "Save."
View 5 RepliesI have seen a number of posts on this, but none that quite serve my needs. I have a GridView with template fields. I use postback because when a value is entered in one field a calculation is done to supply the value in another field. I simply loop through all the rows after each postback (there are not many so it is fast). I do not use a select command or button to select a row. After postback I do not know how to return the focus to the row that was being used. I can return the focus to the first row just by using gridview1.focus.
