How to disable tab or visibility control if some condition is not satisfy.
I want it that control in .asmx page, because I have some Cascaded combo under two tab.
If the first combo is not populate in any of tab then that tab will not visible or disable to user.
As I am populating the cascaded combo box using web methods so it is easy for me to declare that fuction there.
I want to change the visibility of two asp.net image controls (runat="server") at the beginning and the end of the method call duration. I mean, I want the first image displayed and second one remains hidden until the last line of my method, which in turn, the second image becomes visible and the first one hides. I've put the area of the triggering control in updatepanel and have declared triggers of the updatepanel; But when I press the control (which is a button), the image at the end of the process is displayed correctly and on time but the one which should be displayed in the first line of the method is not displayed. I've configured my updatepanel to use conditional update mode and have used these lines for my intention:
imgLoading.Visible = true;
..
rest of the process
..
if (true)
{
imgLoading.Visible = false;
imgSuccess.Visible = true;
}
so here is what i've got:
-master page with updatepanel - within the update panel is a contentplaceholder
-aspx page that uses the master page which contains aysncfileupload,a button,an image,and a label
what i'm trying to accomplish:
when a user uploads a file using the asyncfileupload it gets saved to a public folder.-this works as it should when the user presses the button the file is processed and should display the image and label (which were previously not visible)-this does not what happens is that the file gets processed but the image and label stay hidden,and i cannot figure out why.here's the aspx page and code snippets:
[Code]...
the file gets uploaded,and it even hits the two lines which should make the label and image visible but they stay hidden.i know that if you try to change controls with the afuExcelUsers_UploadedComplete event,they will not happen since the asyncfileupload only does a partial postback. this is why that event (afuExcelUsers_UploadedComplete) only saves the file on the server.then pressing the button triggers a different event and should do a "postback" and have control over the label and images visibility and other properties.
I have a page with 2 update panels
UpdatePanel1 contains a gridview1 and a standard panel, pnlForms. gridview1 has a linkbutton which is processed in the gridview1_rowcommand
UpdatePanel2 has gridview2.
There is also a Submit button that isn't in either UpdatePanel but may be a candidate to go into its own UpdatePanel. The Submit button is a trigger for both update panels
The behavior I would like is:
1-Initially, all visible except pnlForms and Submit button 2- When linkbutton in UpdatePanel1 gridview1 is clicked, pnlForms and Submit button become visible. 3. When Submit button is clicked, both gridviews should be refreshed, and PnlForms and the Submit button should both become not visible. I believe I may have to put the Submit button in its own UpdatePanel3 but am not sure how to proceed.
In my present code, everything works as desired except Submit button (not presently in any Update panel) is always visible. Assuming Submit button is initialized to not visible, how do I get it to appear when I click the link button in gridview1 and to disappear when it is clicked?

I have a main menu option of "Dashboard". Under this menu item I have 2 options: 1) Campaign Manager & 2) Negotiation Manager. Now, what is interesting is when I am in either the campaigns role OR the auto-negotiation role I see the Dashboard and BOTH sub-menu items. This is not the behavior I expected. I expect to only see both sub-menus when I am in the campaigns role AND auto-negotiation role. The OR scenario should give me the Dashboard menu item and one OR the other sub-item...Am I doing something wrong here or thinking a wrong way?
I have a gridview and I have to control the visiblitiy of the grid columns using javascript. Consider this gridview. I have a few columns.
<asp:GridView ID="grdTest" runat="server" AutoGenerateColumns="False" Width="100%">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="chkResource" runat="server" />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Resource">
<ItemTemplate>
<asp:Label ID="Resource" Text='<%# Bind("Resource") %>' runat="server" />
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="Description" HeaderText="Resource Description" HtmlEncode="false">
<ItemStyle HorizontalAlign="Center" />
<HeaderStyle HorizontalAlign="Center" />
</asp:BoundField>
</asp:TemplateField>
</Columns>
</asp:GridView>
I can control the visibility of these columns at the server side by using this -
grdTest.Columns[n].Visible = false;
But, I have to control the visibility from the client side using javascript. I tried a lot but I was only able to access either the row object or any particular cell of the gridview.
grid.rows[index].cells[i].style="display: none"; //for cell
Is there a way to access the column object of the gridview and control its visibility using javascript?
I want to change controls visibility on c#, but nothing happens. The controls are in an AspxPopupControl and 3 of them are hidden in design time, 1 of them is visible. I use this code to visible them
if (paramType == "Grup")
{
gv_Answers.Visible = false;
trlGroup.Visible = true;
chkShowItems.Visible = true;
}
else
{
gv_Answers.Visible = true;
trlGroup.Visible = false;
chkShowItems.Visible = false;
}
This code is in a CustomCallBack event of a gridview. So i don't know what to do from this point. It's an easy task but i couldn't handle it.
I am developing a web application for online bidding wher I want the BID button to disable itself, on all clients, whenever someone places a bid. What I need is some javascript to ping the site to check if a bid has been placed on the server, if so, then disable the button. I was suggested to use jQuery for this, use .ajax to query the server for the check. Then use a setTimeout javascript function to keep checking.I am not javascript expert at all so any tips would be greatly appreciated. At lease where to start. Also, will I need to record every single bid in database to achieve above?

I have a web page where a div needs to be displayed under certain conditions. I'm using the following code to toggle the display and have verified that it works.
[Code]....
To call this javascript function, I'm using the following code in the code-behind for the page:
[Code]....
I traced the flow using the debugger. When the page load, txt_Cat_ID.Text = "2" correctly resolves to FALSE and the toggleOptionsDiv script is run with the 'hide' parameter. The page correctly hides the div.
When I click on the link that makes txt_CAT_ID.Text = "2" resolve to TRUE, the code executes the line where the toggleOptionsDiv script is run with the 'show' parameter. However, the div remains hidden.
The link that is clicked triggers an asynchronous post back and I'm not sure if that is the problem. How can I get the div to display on postback?
For a website I was asked to put a bunch of information inside a few different categories. The tabpanel seemed fitting for this, and the person I made it for approved of the simple and elegant sollution.
However, he now has a somewhat tricky request: he wants it so that when people print (javascript::print()), they would be able to see all the information entered in the different tabs. Normally I would solve a thing like this with a different print rules inside my css file. However, in this case, the javascript attached to the tabcontainer/tabpanels puts the visibility:hidden on the elements themselves, meaning whatever I may write inside the css would be ignored either way.
Is there any simple way of making it so that these tabs will be shown when printing?
Preferably a sollution that doesn't require me to rewrite most of the tabcontainer/panel code or making my own control from scratch. I would think that this "should" be achievable through javascript, but I thought I'd check here for ideas before rushing into things.
I have a custom control which contains a Repeater control. The Repeater has an ItemTemplate. Inside that item template I have a panel which is going to hide something based on "IsEditable" a boolean property of the custom control. What I would like to do is set the panel's visibility once before the Repeater is databound.
I know I could do an onItemDataBound event and use FindControl to get the panel but that seems a little excessive since it will always be either visible or not for all rows and I have no other actions that need to occur on databind. Is there a way to find the control in the ItemTemplate before the Repeater is databound?
http://forums.asp.net/t/1109955.aspx?PageIndex=1
Here is (more) code that demonstrates the issue. If the control in the host page is removed the tab control renders correctly. Otherwise it is rendered with the visibility attrubute set to hidden as reported in the above link. Is this broken or am I doing something wrong?

I have a gridview that displays entries from a data table. I am giving users the ability to select a subset of the data in the table by having a textbox and search button in the grid view header. The search button fires the gridview row command, and changes the underlying sqlDataSource's select command, and adds the text value from the text box as a parameter.
Also, I have a "Show All" button in the header, that clears out the select parameters, so all entries in the table are shown. Again, this works perfectly.
What is NOT working is controlling the visibility of the "Show All" button control. Below is the html markup for the data grid header template:
<HeaderTemplate>
<asp:Button ID="btnShowAll" runat="server" CausesValidation="False" CommandName="ShowAll" Text="Show All" />
<asp:Button ID="btnSearch" runat="server" CausesValidation="True" CommandName="Search" Text="Search" ValidationGroup="vldSearch" /><br />
<asp:TextBox ID="txtSearchName" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="vldSearchName" runat="server" ErrorMessage="You have to provide an attorney name to search for." Text="*" ControlToValidate="txtSearchName" ValidationGroup="vldSearch" ForeColor="White"></asp:RequiredFieldValidator>
</HeaderTemplate>
In the Row Command event handler, here is how I am setting the visibility of the button:
If Not Me.dgAttorneys.HeaderRow Is Nothing Then
Dim btnShowAll As Button = Me.dgAttorneys.HeaderRow.FindControl("btnShowAll")
btnShowAll.Visible = Me.sqlAttorneys.SelectParameters.Count > 0
Trace.Write("Show all status is " & btnShowAll.Visible.ToString)
End If
The trace statement is showing the correct visible status - if the "show all" button is clicked, I do a SelectParameters.Clear() on the sqlAttorneys sqlDataSource.
Is my problem due to a misunderstanding of how the "FindControl" method works - I had assumed my new btnShowAll that I define is actually a reference to the "physical" control on the aspx page, so any changes I make to my local object is reflected in the control on the page.
If this is not the case, what is the best way to get a reference to the button control in the header row of the grid view?

View 6 RepliesI'm trying to dynamically assign the visibility of the TabPanels in my page. The code below sort of works, but not correctly (refer to image).
It is able to hide the actual tab, but the header still appears (though unclickable). I need for the header and the tab to be hidden.
I tried to use "tb = (AjaxControlToolkit.TabPanel)this.page.findControl("TabPanel1").Visible = true"
And get this error Object reference not set to an instance of an object.

I am trying to use the TabContainer/TabPanel controls to create 3 tabs. The tabs themselves will always appear, however, only the first tab will ever display. When I look at the source of the page, I find that the 2nd and 3rd panels have style="visibility:hidden;display:none" on them. The only time this is not true, is if the content inside the tables is text that is on the source, nothing generated.
I have tried it using controls, repeaters, adding all my tabs dynamically, setting the properties of visibility=True and enabled=true. I am kind of pulling my hair out here.
ASPX coding:
<asp:TabContainer ID="aeDetails" runat="server">
<asp:TabPanel ID="placeholder" runat ="server" HeaderText ="PlaceHolder" ><ContentTemplate >Place Holder</ContentTemplate></asp:TabPanel>
</asp:TabContainer>
VB.NET Code:
' Get the content for the home page.
getHomePageContent()
' get the announcements, if any
getAnnouncements()
' get the events, if any
getEvents()
' remove placeholder after adding all three tabs
For i As Integer = 0 To aeDetails.Tabs.Count - 1
If aeDetails.Tabs(i).HeaderText = "PlaceHolder" Then
aeDetails.Tabs.RemoveAt(i)
Exit For
End If
Next
I will only put the code for one tab in here as they are all pretty much the same.
Private Sub getAnnouncements()
Dim nt As TabPanel = New TabPanel()
nt.HeaderText = "Viscardi Announcements"
nt.ID = "tpAnnouncements"
nt.Visible = True
nt.Enabled = True
Dim nl As Label = New Label()
Dim sb As StringBuilder = New StringBuilder()
Dim anRec As HVS_Announcements_Record = New HVS_Announcements_Record
Dim anList As List(Of HVS_Announcements_Record) = getCurrentAnnouncments()
Select Case anList.Count < 1
Case True
nl.Text = "There are currently no announcments for the Henry Viscardi School"
nt.Controls.Add(nl)
aeDetails.Tabs.Add(nt)
Return
End Select
sb.Append("<ul>")
For Each anRec In anList
sb.Append("<li><a onclick='MM_openBrWindow")
sb.Append("('announcementDetails.aspx?id=" & anRec.HVS_AR_Id & "','newWindow','status=yes,scrollbars=yes,resizable=yes,width=600,height=500'")
sb.Append("target='_blank' title='Click to view full contents of the announcements'>")
sb.Append(anRec.HVS_AR_AnnouncementTitle & "</a></li>")
Next
sb.Append("</ul>")
nl.Text = sb.ToString()
nt.Controls.Add(nl)
aeDetails.Tabs.Add(nt)
End Sub
All of the content that is generated by the various routines is in the page source, just hidden.
I am using calender control I want to change it's visibility on button click event. This is my form design:

<asp:Button ID="Button1" runat="server" Text="Show" />
</form>

How is this best accomplished. I see that intellisense does not have a visibility attribute for Menu1.Items(1).
I have a problem with disabling the tabcontainer.
The problem is that, if a user haven't selected anything, the whole tabcontainer must be disabled. If I disable the tabcontainer it in de codebind, the tabcontainer grayed out but the user can click the tabs.
I can disable one tab in javascript but how can I disable the whole tabcontainer?
I need to achieve an effect of a read-only textbox, where when the user clicks on the textbox a popup grid control appears, after the user has made a row selection the text box is populated.... Looking at the AJAX Toolkit model it seems like a CustomExtender would be the way to go, but I can find no documentation on how to build such a thing, so I am looking at improvising.
Here is my process (which is still not working):
Using either an ASP.NET TextBox or HTML <input type="text" runat="server"> control I need to able to trap on the onclick event and then set an ASP.NET Panel control Visible="true". I have tried placing my GridView control inside a <div> and using style properties to set it to hidden and using a client-side (javascript) event handler on <input type="text"> onclick event setting the style property to visible, this does not work correctly. It results in a empty place-holder like grid that popualtes on click (I suspect this is because the DataGridView lives inside a ASP.NET Panel)
I would like to be able to call a server-side method from inside my client-side JavaScript function. I seem to recall from Microsoft AJAX 1.0 docs a way to RegisterClientScript or some approach that allows this and can not find anything on this being supported with the ControlToolkit/MS AJAX 2. If I can do this I could set my ASP.NET Panel Visible property to true and then call Update() on it's UpdatePanel parent which should give me exactly what I'm looking for.
