Web Forms :: FindControl On Default.aspx In MasterPage.CodeBehind
Dec 11, 2010
I was wondering if it is possible to find a control in a standard web form that is using a masterpage.
So for example I have two pages - default.aspx and information.aspx. Both these web forms have label controls (lblDefault and lblInfo respectively). This information is stored in a database along with the content that the label controls should be populated with. Instead of having to program a method to retrieve the content text from the database for the relevent controls on these two pages would it be possible to find the controls in the masterpage codebehind file - something like Page.Form.FindControl("lblDefault")? So for each webform using a masterpage a check is done to see if any of the controls should be populated with content from the database.
I'm very new to .net and Visual studio. When u create a new website, a blank page default.aspx is displayed. Then u click on add new item & select master page. How to add this masterpage to default.aspx?
For example, I have master page MyMasterPage.aspx and content page MyDefault.aspx. I have many UpdatePanels at MyMaterPage.aspx, and also I have many UpdatePanels at MyDefault.aspx.
[code]....
I want JavaScript functionClickMenu(this) at input button [id="ButtonMaster1" @ MyMasterPage.aspx] pass its value ["Menu-1"] into text box [id="TextBoxDefault1" @ MyDefault.aspx], and then performing update / doing post-back to server ONLY FOR UpdatePanelDefault1.
I am looking forward an example code for JavaScript functionClickMenu(this).
If I use the FindControl Method on an .aspx page (without master page), it finds the desired control no problem. When I use a Master Page then it will not find it even though it exists. why is this?
In the gridview we are using edit button. Once the edit button click Controls in the edit template will display in the same row with update button. That row has two dropdownlist control.
Process flow:
controls:d1 and d2
d1 is using sqldatasource for item display : working fine. d2 is using codebehind code to load the item based on the selected value in the d1 : Not working
How to findthe control in the edit template to display item value for d2.
i have a masterpage and other pages. i want to use findcontrol method to find a textbox (not on the master page) to check whether it is empty or not.
my code is as folows; Dim myContentPlaceHolder As ContentPlaceHolder = CType(Master.FindControl("MainContent"), ContentPlaceHolder) Dim UpdatePanel1 As UpdatePanel = CType(myContentPlaceHolder.FindControl("UP1"), UpdatePanel)
I have a simple FormView (fvDespatchPart) which updates the status of an order and it's despatch date; the despatch date being retrieved from a textbox (txtRentalDespatchDate) held within the FormView. The FormView's DefaultMode is set to Edit.
I have been trying to set the default entry for txtRentalDespatchDate to today's date in the code behind, using:
Dim dtNow As Date = Today()
Dim txtRentalDespatchDate As Webcontrols.Textbox = fvDespatchPart.FindControl("txtRentalDespatchDate") [code].....
I have had no trouble doing this in the past with FormViews whose default mode is set to Insert or Item, but in Edit mode it just does not seem to want to co-operate. I have read a few help posts, and have tried:
Putting that code in LoadComplete, PreRender, PreRenderComplete Page events, as well as the FormView's databound event. I've also tried nesting it within a ...
If fvDespatchPart.CurrentMode = FormViewMode.Edit Then
End If
... just to make sure if is in the right mode.
Nothing yet has resulted in anything but the same old error.
i want to know, if is better to make an entire page in the aspx file or in the aspx.vb file. If you have to decide, which one do you choose? ie in aspx:
Code: <asp:Table ID="Table1" runat="server" Width="980"> <asp:TableRow> <asp:TableCell> SOME TEXT </asp:TableCell> </asp:TableRow> </asp:Table> ie in aspx.vb: Code: dim tabla as new table tabla.id = "Table1" tabla.width = 980 dim fila as new tablerow dim celda as new tablecell celda.text = "SOME TEXT" fila.cells.add(celda) tabla.rows.add(fila) form1.controls.add(tabla)
I am trying to secure very mixed content that is located in an ASP.NET directory. For purposes of this question, it can be ~/MyApp/.
I want all of the content in the directory and its subdirectories restricted to authenticated users. The default.aspx page, though, should be accessible to everyone. This is the web.config in that directory:
[Code]....
Now if you are an unauthenticated user, everything works fine if you request [code]....
The problem occurs in that visitors do not always request "Default.aspx". We have a default document configured so that they get Default.aspx even if they just request "/MyApp". An authenticated user works fine, but an unauthenticated user is directed to the login page.
Now I know that essentially this happens because even though the request for "/MyApp/" will actually end up serving up "/MyApp/Default.aspx", the security system is only checking for "/MyApp/" since that is what I requested. That is then getting the default security for the directory.
How can you configure an exception to allow access when no particular file is requested in the directory??
Is there some dependency between DefaultDocumentModule and UrlAuthorizationModule? In this environment, the UrlAuthorizationModule has been removed and re-added in order to make sure it fires for non-managed requests. I would not expect that to change the order of execution, though, since UrlAuthorizationModule usually goes after DefaultDocument.
A workaround could be to set up the opposite security with the directory being open, and then trying to secure individual files. Because of the (changing) number of files, and extensions, etc, and the fact that you cannot use wildcards in a <location>, this is not really a workable solution for me.
I have the following javascript tag inside my aspx head
[Code]....
GetWithCdn is a public method inside the codebehind file. but this is not getting called when i run the page? can anyone tell me why this is happening. because same method worked on a different page.
is it possible to put two different contentPlaceHolder from two different ASPX page in one MasterPage? Just like iFrame? if not what asp.net process/control can?
How can I convert the following aspx code into code behind code?
[Code]....
I want the following code to be craeated on the fly (runtime). I will only add the root level grid to aspx and then in page load I want to add subsequent grids.I know we will use GridViewTemplate to add the grid but not sure how to structure it. The steps that I follow:
1. set the required properties of gridLevel01.
2. add BoundFields for level01.
3. Add template field for level02 grid....but not sure how to set other required properties like color and stuff....also not sure what position to add the subsequent gridviews.
Do I need to add the child grids to root?? I know the level2 grid will be added to level1 but what about level 3?
I have been trying to call a vb.net function in aspx page how can i do that?. I have done it in C# by
<td><#%GetItemIndex(Container.ItemIndex)%></td> its working fine in C# but in vb.net it says GetItemIndex not declared.
and trying to convert (rptpages is a repeater)
rptpages.Itemcommand += New RepeaterCommandEventHandler( rptpages_ItemCommand1) from C# to VB.net but i dont see itemcommand property in VB.net for the repeater.
I am having some trouble, I am very new to asp.net, and the last problem I had, I spent about 59 hours trying to solve, Now I have a new one !
:D well, I guess this is part of the learning process...
Well, in Visual Studio 2010, I clicked New Website. @ C# language, ... The template it gives is pretty nice, it creates a database MDF file, and a login/register setup ready to go !...
You guys can see it live AT CLICK HERE ...
Everything is working, well at least here at the local machine...
There are 2 pages in there, Default.aspX, and About.aspx ... I want to allow ONLY logged in users to view those 2 pages... I tryed a few things, added my account to a role called ADMIN,
In the web.cong I changed Allow"*" to allow"ADMIN" ... still didn't work.. Also, I was trying to avoid using roles for now, and I was trying to find a way to do this for individual pages in the same directory as well... If possible with out touching the web.config file...
Here is my scenario.In default.aspx page user selects the country, state, city from drop down list, and store them in cache for further use. but when other user open the web site from other computer it shows the same country, state, and city selected by user 1. Is there any problem related to cache? I have stored data as following.
cache["ctryID"] = ctryID;
cache["stateID"]= stateID;
cache["cityID"]= cityID;
I want to show default country, state , city at page load of default.aspx
