I have my webpage with some custom controls which all inherit from BaseWebControl.
Let's say in Controls A in a foreach loop I add my Control B. My Control be contains some other standard controls like text boxes, check boxes etc.
The I have a button which invokes a method in my control A. In that method I want to find a checbox control which is a part of Control B. Unfortunatly I can't find it. The only aviable controls in Control A in my Control B. When I check the ControlB.Controls they are null, although they appear on my website correctly.
In IE web developer toolbar I check the IDs of the controls and I generate the exact same string in my code to pass on to the FindControl method.
I have a gridview in my web page. I have boundcolumn,checkboxcolumn and a linkbutton column. The commandName of the linkbutton column is "Select" The name of the template checkbox is "chkSwapSelect". I want to check the checkbox of the linkbutton clicked row. When i click the linkbutton of the gridview RowCommand Event fires
if e.commandName="Select" then Dim index as integer=Integer.Parse(e.CommandArgument) Dim row as GridVIewRow=dgvAllocation.rows(index) dim chk as checkbox chk=new checkbox chk=ctype(row.FindControl("chkSwapSelect"),checkbox) // chk returns nothing chk.checked=true // object reference not set to an instance of the object end if
The errors are shown as comments in the above code. finding the controls inside a gridview via RowCommand Event
On load I'm both calling a JavaScript setTimeout() function that will hide a .NET Panel control, and hiding it in the code behind on first load. Clicking the save button will set the Panel to visible then reload the page at which point a setTimeout() function is called... so basically you click save, and see a panel with "Details Saved" for three seconds, at which point it disappears.
The problem is the external JavaScript file can't find _pDivAlert.ClientID (I've debugged and it returns null). It only works when the code is in a tag in the .aspx page. how I can either pass the client ID to the HideControl() function or find the ClientID from the external JS file?
We have a mid-sized asp.net project that we just promoted from our dev server (Windows 2003) to an external test server (Windows 2008 R2). On the test server, IIS is not finding our home page, which is located in the views/home folder (404 error). As far as we can tell, the settings are the same on both servers. I've confirmed HTTP redirection is installed. Is there perhaps some critical configuration we may have missed on IIS7.5 to let it know where to find the view and/or home page?
I am trying to create strogly typed datasets for my project. When I right click on the xsd file that I need to generate a strongly typed dataset for I can't find the 'Advanced' properties as described in the below article (almost half way down)[URL]As I do not see the Advanced properties option I can't find the 'Custom Tool' property/option to set its value to 'MSDatasetGenerator'. Do I have to install some kind of patch on my VS 2005?
My ASP.Net app is periodically getting the error 'Cannot find the object dbo."XXXX" because it does not exist or you do not have permissions' when it tries to execute a specific stored procedure that writes to the database. I have seen a few forum posts about this issue but the strange thing is that the method works fine almost all of the time, just every now and then I see it in my error logs. Can anyone tell me why this might works Ok most of the time but occassionally fire the error?
Application is C# using Enterprise Library 4.1 Data Access. Database is SQL Server 2005
I have a C# ASP.NET MVC application which has been using jquery 1.3.2 in VS2008 environment.
I decided to upgrade to 1.4.2 and added the file to my project. Changed the reference in my masterpage header to the new version. But now nothing works, it's like it can't find the jquery library.
i get the following exception (missing primary key) in the line of using Find() method "Table doesn't have a primary key." I've rechecked the Database and all Primary Key columns are set correctly.
DataTable dt = p.GetAllPhotos(int.Parse(Id)); DataTable temp = new DataTable(); temp = dt.Clone(); temp = (DataTable)(Session["currentImage"]); DataTable dtvalid = new DataTable(); dtvalid = dt.Clone(); DataRow[] drr = new DataRow[1]; drr[0] = dt.Rows.Find((int.Parse(temp.Rows[0]["photoId"].ToString()))+1); foreach (DataRow dr in drr) { dtvalid.ImportRow(dr); } dtvalid.AcceptChanges();'
I have method that I call which needs to find all the panels in the page but it fails. I have another method that was created by the VS has the traditional paraeters such the object sender, EventArgs e that the similar code works fine but the (simplyfied) code below. It is clear to me that these parameters contain information that makes one method work while the other not, but I don't know why.
The code breaks on the last line of code: _pnlAssetInfo = (Panel.....
I want to find the ID's of all the controls in my website. I have written a seperate class and i am calling it from each page to get the ID's. That works fine.
At the application_start event i want to get the ID's of all the controls in each page of my website and save it to the DB.
I want to call the function only once in my application's life cycle. I want to call the function for each page, from the application_start event.. From the DB i take these controls for specifying access rights which is one of my modules.
I have a web page with several panels. I one particular panel, I have several radiobuttonlist controls. I added a LinkButton to my web page and when clicked, I want to clear the values in all my radiobuttonlist controls. I have this so far:
Protected Sub ClearRBL(ByVal sender as Object, ByVal e as EventArgs) Handles lbClear.Click Dim ctl as Control For Each ctl In Page.Controls If TypeOf ctl Is RadioButtonList Then DirectCast(ctl, RadioButtonList).ClearSelection() End If Next End Sub
But this does not work. The If TypeOf ctl Is RadioButtonList Then line never finds a RadioButtonList control. How can I make this work?
