AJAX :: Update Panel With Async Trigger Not Working?
Sep 20, 2010
I have following code and when I select from my drop down list the progress controls do not show and my grdiview is not being filled either. If I leave out the update panel from my code things are working fine.
I am trying to create a simple web application that uses a barcode scanner to read the barcode and then insert the information into a database. I have been able to get the barcode scanner to read the barcode and place the information into a textbox.
The problem that I am having is that I can get it to post back 26 times then it will go to error (with no information). If I then add additional controls to the page I can only get it to post back 10 times. Below is my code... I have been pulling my hair out for the last two days.
I am building a system for a school project. I currently have several Update Panels on the page that have many different controls on them. I also have a single Label control that i use to display messages to the user. I would like to have this label within an update panel also but there are literally hundreds of triggers that would require it to be updated and i dont want to type an absurd number of triggers for this one control.Is there a way for me to have this one panel update regardless of what happens?
I have update panel , in update panel i have one button control which exposes onlientClick event ( it dosent have click event to do postback to server).
and i have one updateprogress panel. So my problem is though i'm performing operation on client side , internally the async event is firing and making updateprogress panel to act (having rotation gif image) which i dont want , as it rotates for 10-15 sec more even after the operation at client side is done !
i have 2 dropdownlist on my asp page.first dropdownlist value gets selected from a pop up window.now i want to fire an event from the drop down list as the drop down list index changes.The dropdownlist is in update pannel and i want to invoke the server side event of dropdownlist so that the other dropdownlist can be populated.
In my application I am using ajax updatepannel in which there is a tab container tool having 4 tabs, in the third third tab I used ajax accordian control which has 2 panel each pannel have one gridview control a Remove button. Here what I want to give delete facility to the user upon the selection of checkbox corresponding to the particular record. But when I click the button it doesnot triger the button click event of the remove button.
I'm new to the world of Update Panels and i'm having a hard time figuring out how to use them properly.
I have a form that has a table(TABLE1)...and inside TABLE1 i am linking to a sql data source....at the bottom of the table i have a 'Add' button.
When the user clicks the add button...a modal popup appears (POPUP1) and inside the POPUP1 the user can click a link that can add a user...when the link button is clicked...a panel within POPUP1 is set to visible = true.
I have one update panel around the whole table and the add button...when i click add and then click the link to add a user....the modal popup disappears.
in my Site i have 3 updatepanels.In the 1 is the gridview. with templatefield in this is the imagebutton. ImageButton has commandname "Select" want to register the ImageButton as AsyncTrigger for the other Updatepanels 2 and 3
I want to create a searching work to fill the gridview detail acc to seach params.. When we enter text into search textbox it fills the grid, that works filne without postback. After this i have to fill the form values accroding to link clicked in Gridview. I uses the updatapanel in grid like
When the grid fills it doesnt fill my form... why it happens.. i used the Updatapanels multiple as well.. If i use the Updatepanel in whole.. it may flicker while filling in the form values.
I am having a treeview in Masterpage,all tree items are associated with different page,when i click on any of the tree item,i the respective page should be displayed in the ContentPlaceHolder of the masterpage without postback,
i kept the treeview and the contentplaceholder in the updatepanel,still it is not working,means entire page is posting back to server
I have one button on my page. On click of this I need to run four methods parallely in four saperate thead and need to show the progress bar for each method. Also need to update the label controls form those threaded methods.
Also I need to user Update panel of AJAX control tool kit to avoid post back to user.
I have used the read pool for that. When I remove the update panel the code works fine and update four labels but when I put the update panel it is not updating the labels.
