Forms Data Controls :: Cannot Trigger A Postback / Databind Of Gridview

unless you page to the next group of records.

View 5 RepliesForms Data Controls :: DataBind In A PostBack Event?
Oct 25, 2010 My data-binding problem is this: I have a user control that contains a DataList, withing the user control I have an array of objects that are binded to the data list. This works fine and the datalist displays exactly what I want. I have also set up an event that changes the background color of one of the controls on a click. So when the click event happens through a bubble event I change the controls backcolor and then try to call the DataList.DataBind(). This does not work when all the controls Page_Load happens my binded object from the Array is now null. All the examples I have found in code that seem to work have you recreating the data source before calling the DataBind function in the PostBackEvent asp.net step. I don't understand why this is or how I'm suppose to resolve my situation since my datasource in my user control can't easily be recreated. I hope I explained this well I have included a test program that sort of duplicates the issue I'm having. If you run this code you will not get the data list to display at all on a click event. But if you call the BindList function it will work correctly.

Refresh A Page Without Postback?
May 3, 2010There is a asp:Label in the page for showing message from server.
The message can be sent by server at any time.
I added a handler to update the Label's Text, like following:
void MessageReceived(object senders, EventArgsMessageReceived e)
{
lblMessage.Text = e.Message;
lblMessage.DataBind(); //To show the message
}
I am sure the break point of 'lblMessage.Text = e.Message;'' is hitted.
But the DataBind() seems not work, and the label isn't updated.

View 2 Replies.net - Difference Between An F5 Browser Refresh And Postback?
Jul 22, 2010I am dynamically creating dragrids in different rows of an existing datagrid in asp.NET
My generated datagrids have a column which is TemplateColumn (a CheckBox Column).
In my parent datagrid, I have a template column with checkboxes. when I check or uncheck the value of the check box, the check_change method is called (autopostback is set to true), the dynamically generated datagrids lose the checked checkboxes (the checkboxes are all unchecked again). However, if i check any of the checkboxes of the child (dynamically generated) grids and press F5, it refreshes the page but still I have my checked checkboxes.
What's happening ?? how is post-back different from refresh F5??? understanding this might help me fix my problem here :DataGrid not being altered!
Web Forms :: Refresh A Page On Postback?

postback page load loop and data doesn't get saved to the DB so I have to use If not Page.IsPostback then to avoid the loop.

AJAX :: Getting Dropdownlist To Update Without Postback / Refresh
Jun 27, 2010I have a number of cascading dropdownlist controls on a page. The results in dropdownlist2 are dependent on the results in dropdownlist1, pretty basic stuff.

What I want the results in dropdownlist2 to populate without the obvious refresh of the page.
Refresh A Control On The Master Page After Postback?
Apr 12, 2010What i am trying to do here is to show a couple of validation messages in form of a bulletlist, so i have a Div on my master page containing a asp:bulletlist. Like this:
<div>
<asp:BulletedList ID="blstValidationErrorMessage" runat="server" BulletStyle="Disc">
</asp:BulletedList>
</div>
When i then click the Save button from any of my pages (inside the main contentPlaceHolder) i create a list of messages and give this list as datasouce like this:
blstValidationErrorMessage.DataSource = validationMessageCollection;
blstValidationErrorMessage.DataBind();
The save button is located inside an updatepanel:
asp:UpdatePanel runat="server" ID="UpdatePanel" ChildrenAsTriggers="true" UpdateMode="Conditional">
Nothing happens, i can see that the datasource of the bulletlist contains X items, the problems must arise because the Save button is inside an update panel and the elements outside this updatepanel (master page controls for example) is not refreshed.
So my question is, how do i make the bulletlist refresh after the postback?
AJAX :: Postback Does Not Reset Meta Refresh Tag?
Feb 25, 2010I have a kiosk application that uses master pages. There is a refresh meta-tag on the master page (or I can add it programmatically using Page.Header.Controls.add(metaTag), it makes no difference for my problem). When the user does not interact with the aplication it should return to the default page. But when the user does react using async postbacks only a partial postback is performed which does not reset the html meta refresh header, so it just keeps on ticking and after x seconds the page redirects to the default page. How can I avoid this from happening. The meta-tag can not be in the updatepanel so even though I can manipulate it from the code-behind when the async postback happens, any changes I make (for example sometimes when the user makes a mistake he should be redirected to a clean version of the page he is currently on after showing a modal message, so I have to change the url of the meta-tag content to no longer use the default page, but the current page) are not implemented.So the main question is, how can I manipulate (or reset in case of refresh meta tag) meta-tags in an async postback ?

State Management :: Postback Not Refreshing Datasource - How To Refresh It
Apr 27, 2010I have a linkbutton that displays a different record each time the page is loaded. When I first bring the page up, I can hit F5 repeatedly and the linkbutton works properly rendering a diff record each time. But in a dropdown list, or any other control that causes a postback, the linkbutton remains static, why?
In my Page_load I have
AccessDataSource1.SelectCommand = "SELECT blah FROM table where trim(recid)=" &
"'" & rndVal &
"'"
AccessDataSource1.DataBind()
LinkButton1.Text = DetailsView1.Rows(0).Cells(1).Text
Web Forms :: User Control Refresh / How To Trigger A Postback
Jan 27, 2011I have around 8 user controls on a page with a form in each of them. I have a dropdown list that allows you to select a form, with a selectedindexchanged event that hides the current form and shows the requested form.
There is some javascript that needs to fire when each form loads. Now, when you click on a form for the first time, the javascript fires as it should, but if you click the dropdown to change the form, then click back to a previous form, the javascript doesn't fire (because the user control is already loaded).
Is there anything I can do to trigger a postback, or reload/refresh the user control whenever an option is selected from the drop down?
Web Forms :: Trigger A Postback Or Self Refresh A User Control?

Problem is that I am setting the selected value of a dropdown control in this usercontrol but it does not actually show up until after a postback.
This I came to know after I found that the said drop down shows the current value only after I click on another button.
I need to do this on the server side in the function given below:

{
FillProgramList(select);

AJAX :: Refresh Slideshow Extender With New Contextkey Without Postback
Apr 8, 2010I have a slideshow extender, I will change the slideshow extender's contextkey value by a button click event. So that after button click the slideshow will display different set of image. Originally with postback everything work fine, but I don't want the whole page to refresh.
So I put the slideshow extender inside an updatepanel with triggers target the button click event. Now the whole page didn't refresh and the slideshow extender's contextkey value did change (same code as before) after button click event. However the image set on the slideshow didn't change.
I think I am missing some sort of slideshow extender reload or refresh call but I am not sure how to do this? I didn't see any related property with slideshow extender...
