AJAX :: Add Tab Via Click, Using UpdatePanel?

Jan 21, 2011

I am trying to have a TabContainer with a dynamic/changeable number of tabs: when the user clicks on the last tab labeled "New", a new tab is added to the list. There are two issues:

1) The tab container's ActiveTabChanged event fires twice, adding two tabs. Why is that?

2) Any further clicking on the tabs gives an error, "There is no source code at the current location." How is that possible?

My ASPX:

I have a master page containing a ScriptManager control, and a Content Page containing a ScriptManagerProxy Control.

AJAX :: How To Mimic Button Click Inside UpdatePanel With JQuery

Mar 7, 2011

I've a dropdown and a listview inside an updatepanel (Master/Child relationship) so based on value selected in dropdown the listview gets populated. The Listview allow user to perform Edit/Insert/delete of records. I have to implement a scenario when a user is editing/inserting a record and if he tries to navigate away/change the value in dropdown he should be prompted to save the data and if he choose yes in JS Confirm Dialogue then the currently edited/inserting record should be saved (for which i'm trying to mimic the click of the update/insert button using js). I've attached change eventhandler of dropdown using JQuery which is getting called properly bind.
[Code]....

This code gets bind using
Sys.Application.add_load(saveChanges);
I also tried the following
Sys.WebForms.PageRequestManager.getInstance().add_initializeRequest(saveChanges);Sys.WebForms.PageRequestManager.getInstance().add_endRequest(saveChanges). The eventhandler gets called correctly but the click() doesn't work! Also the reason I'm calling click() method of button is to perform the validations via RequireValidator/RangeValidators.

AJAX :: Set The Visibility My UpdatePanel To True Upon A Button Click Event

Mar 1, 2010

I'm attempting to set the visibility my UpdatePanel to true upon a button click event (as shown below). It should be rather straightforward but unfortunately it's not working at all. Any idea why it's going wrong?

//Markup
<asp:UpdatePanel ID="UpdatePanelSearchSubject" runat="server" UpdateMode="Always" Visible="false">
<ContentTemplate>
<p>
</p>
<p>
<asp:TextBox ID="findSubject" runat="server" Width="248px"></asp:TextBox>
</p>
<asp:RadioButton ID="peopleSearch" runat="server" Checked="True"
Text="People" GroupName="searchSubject" />
<asp:RadioButton ID="groupSearch" runat="server" Text="Group"
GroupName="searchSubject" />
<br />
<asp:Button ID="btnGetGroups" runat="server" Text="Search"
OnClick="btnGetGroups_Click" BackColor="#CCFFCC" />
<br />
<br />
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnSearchSubject" />
</Triggers>
</asp:UpdatePanel>
//code behind
protected void btnSearchSubject_Click(object sender, EventArgs e)
{
UpdatePanelSearchSubject.Visible = true;

AJAX :: Change Textbox Backcolor In An Updatepanel On Button Click?

Mar 22, 2010

I'm using a searchoption on my website. (language = VB)

The user can choose a searchcriteria out of a dropdownlist (Artist name, Description, Price, Genre, Type) . If the user selects one of the options in the dropdownlist the correct textboxes are shown.

For example: if the user selects Price he gets two textboxes (one for the min price and one for the max price) if the user selects Artist Name he gets one textbox

The dropdownlist and the textboxes are put into an updatepanel. The searchbutton is outside the updatepanel.

Now for the problem:

If the user doesn't fill in a textbox and presses the searchbutton, the backcolor of that empty textbox should be turned red. The searchbutton is set as a trigger and the panel is updated on the buttonclick, but the colors don't show.

In the clickevent of the button I've said the following code:

If txtCriteria.text = "" then
txtCriteria.backcolor = Red
Else
txtCriteria.backcolor = White
End if

Quite a simple piece of code. This works if I remove the updatepanel from my page, but I'd like to keep the updatepanel because it's really nice :p.

AJAX :: Showing A Control On Click Of Linkbutton Column Of Gridview (present Inside UpdatePanel)

Jan 8, 2010

I have put my gridView inside an UpdatePanel with Timer control for auto refresh.The gridView has a linkButton column which is bounded to referenceNo column from database.

On click of this link button i want a panel to get visible. This Panel contains details corresponding to the referenceNo shown in differnt controls (mostly texboxes). Do i necessarily need to put the panel inside the Update Panel.If not how do i do it?

I have tried putting panel outside UpdatePanel, but it doesn't show panel on clicking the linkbutton nor does the values are updated inside this panel (if panel's visibility is set to true by default for testing purpose).

AJAX :: How To Change UpdatePanel Content From Another UpdatePanel

Jun 23, 2010

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?
