AJAX :: Wrapping Controls In UpdatePanel?

May 17, 2010

I have a page that is essentially a group of controls on top, a button in the middle and a DataGrid at the bottom.

I wanted some asynchronous code to get ran; so I wrapped the bottom DataGrid in an UpdatePanel and made the button in the middle as the async trigger. This is working great. However, the button also needs to clear out the values of the controls up top after it adds to the bottom DataGrid.

The code to clear these controls out gets ran, but nothing changes on screen. I assume this is because the top controls need to be wrapped in an UpdatePanel as well. I did this, but I'm having a problem.

One of the controls up top is an asp:ImageButton. Clicking on this button executes a handler for the click event in the VB code behind. This VB constructs a Javascript snippet that opens a new window with a different page (don't ask me why it is done this way). That VB code gets executed, but nothing happens.

Forms Data Controls :: Wrapping Gridview Columns

Feb 18, 2011

I have a gridView that I want to only show 5 columns per "Row". To explain, lets say I have a gridView that has a total of 20 columns. Normally this would mean that the grid would show all 20 columns in a single row side by side:col1 col2 col3 col4 col5 col6 col7 col8 col9 col10 ... etcI want it to instead show the columns underneath each other like so:

col1 col2 col3 col4 col5
col6 col7 col8 col9 col10
col11 col12 col13 col14 col15
col16 col17 col18 col19 col20

of course the prespective data associated with the columns would show below each column header.I have read some posts and they are pointing me to a repeator but I am not sure how I would impliment a method like that. Any suggestions / examples of ways you have done so or read about?

I'm trying to create a few custom web controls wrapping some existing controls. One of them, for instance, is a wrap for a textbox (because I need additional behaviors such as corresponding validators). The problem is, I'm not sure how to get the data of that control to be sent in the postback.

I have a dropdownlist, that causes a postback. On the SelectedIndexChanged event, is it possible to force a placeholder that is within a different UpdatePanel to change it's visibility?

For example, when the SelectedItem.Value of DropDownList1 is "1" then show Placeholder1, otherwise hide it.

What I am most interested in is how to configure the UpdatePanels to allow this.

AJAX :: How To Trigger Updatepanel Postback From Another Updatepanel

Mar 4, 2011

I have a web user control with one updatepanel (pnlUpdate_2), some controls and one apply button. I display the web user control as a modalpopup in my default page. In my default page i have an updatepanel (pnlUpdate_1) with a gridview and I modify that gridview with the apply button of the web user control. The web user control is for made a custom search of the gridview data. I have a problem with both updatepanels. If I set the updatemode as always in one of them (pnlUpdate_1) and the other as conditional (pnlUpdate_2), the pnlUpdate_1 make a postback in the pnlUpdate_2; I'm not an expert on this but I think that's why the pnlUpdate_2 disappear and reappear after postback of some controls in that updatepanel (not the apply button, it close the modal after postback). I try all the combinations and the problem persists. So I put both updatepanels as conditional and in some way it works; now the problem is that when I click the apply button in pnlUpdate_2 to modify the gridview in pnlUpdate_1 the pnlUpdate_1 not made the postback I get the pnlUpdate_2 postback when I use some control inside the pnlUpdate_1.

How can I postback the pnlUpdate1 from pnlUpdate_2 with the apply button?

AJAX :: Controls Disappear In UpdatePanel?

Sep 10, 2010

I have an update panel and inside the update panel I have a button. When I click that button I want to show textbox which is hidden (i.e. style="display:none"). I want to do it from client side. I wrote a javascript to show the textbox. But the textbox disappears after it is shown.

my button code looks like this: <asp:ImageButton id="b1" OnClientClick="showTextBox();">.

showTextBox() code is called and it displays the textbox, but the click event goes to the server and comes back and when it comes back it doesnt know about the newly added textbox i guess. Is there an easy way to show the textbox from the client side without going to the server inside UpdatePanel.

AJAX :: Affect Controls Outside The UpdatePanel?

Jun 4, 2010

I have a web page with an UpdatePanel containing two GridViews and related controls. There is a Save button on the page outside the UpdatePanel. One of the event handlers for a control inside the UpdatePanel calls a method DisplaySaveButton, which is supposed to make the Save button visible or not depending on a parameter. Although DisplaySaveButton is called & executed correctly, it does not effect the visibility of the Save button.

If I remove the UpdatePanel from the form, leaving all its content behind, everything works perfectly.

how do I affect the state of a control outside the UpdatePanel?

AJAX :: UpdatePanel: Controls Inside Are Now Inaccessible?

Aug 25, 2010

I had a group of controls. They were programmatically referenced so that I could change the text of the labels. It all worked well. So I just put an update panel in and put the controls [i]inside[/i] the UpdatePanel. Now the code that references these labels inside the update panel are no longer recognized. I imagine it's because they are inside the updatepanel now. But for some reason, the web application still works correctly, but the code is blotched up with errors every time a label inside the updatepanel is referenced. My question is, how do I programmatically reference the labels that are located inside the update panel?

AJAX :: Dynamically Adding Controls To A Page With An Updatepanel?

Nov 14, 2010

I am dynamically adding controls to a page with an updatepanel. The controls do trigger a post back but their events do not fire.

For example:

LinkButton link =
new
LinkButton();
link.Height = 45;
link.Width = 250;
link.Font.Underline =
link.Font.Bold =
link.ValidationGroup = "NoValidation";
link.Click += new
EventHandler(EventDoesNotFire);

I have set a break point on the Load_Page and in the EventDoesNotFire method. The Load_Page fires, but it never enters the EverDoesNotFire method.
