I have seen some other posts on how to get this working ... however none of them seem to be concerned with case where you have sublcassed the GridView as your own custom server control.I am attempting to set these properties to get the GridView to render a thead element but I continually get a null reference exception. Any takers?Here is the DatBind method I overrided
new public void DataBind()
{
base.DataBind();
[code]...
I have a curious issue,I am using a combination of asp.net controls with Jquery and am using the JQuery plug called datatables. Instead of applying this to a html table, I applied it to an asp.net gridview. To get it to work, I had to add the thead and tbody tags to the grid like so in the c#:
tablename.UseAccessibleHeader = true;tablename.HeaderRow.TableSection = TableRowSection.TableHeader;
The issue is, is when data is filtered in the table, often there are no results and the emptydatatemplate is used. When this occurs the thead and tbody tags are not in the source outputted by the browser, and an occur occurs and the jquery does not function. Error: 'asSorting' is null or not an objectDoes anyone know a solution? I need to use both the gridview and the jquery datatables ideally.
After render group name comes in the name attribute with different name for each radiobutton in the gridview.
I tried to set all the names as same. But when we see the source in the browser it is unique.
How to change the name for all the radiobutton in the gridview as same.
protected override void Render(HtmlTextWriter writer)
{
System.IO.StringWriter sw = new System.IO.StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
ase.Render(htw);
htw.Close();
string h = sw.ToString();
RadioButton first = (RadioButton)gvAddOption.Rows[0].Cells[3].FindControl("rblValue");
string uniqGroupName = first.UniqueID;
uniqGroupName = uniqGroupName.Replace(first.ID, first.GroupName);
foreach (GridViewRow row in gvAddOption.Rows)
{
RadioButton val = (RadioButton)row.Cells[3].FindControl("rblValue");
string eachGroupName = val.UniqueID;
eachGroupName = eachGroupName.Replace(val.ID, val.GroupName);
//h.Replace("name="" + eachGroupName + """, "name="" + uniqGroupName + """);
h.Replace(eachGroupName, uniqGroupName);
}
writer.Write(h);
}
I have an xml document that has a structure like so:
<?xml version="1.0" encoding="iso-8859-1" ?>
- <newdataset xml="version="1.0" encoding="iso-8859-1"">
- <officelist>
<officeid>2</officeid>
<office>Office</office>
<region>BC</region>
I would like to have the office id = 2 to be its own element. Like so
<?xml version="1.0" encoding="iso-8859-1" ?>
<newdataset xml="version="1.0" encoding="iso-8859-1"">
<officelist>
<officeid id=2/>
<office>Office</office>
<region>BC</region>
</officeid>
</officelist>
</newdataset>
xmlDS += offices.GetXml();
xmlDS = xmlDS.Replace(@"xml:space=""preserve""", " ");
XmlDocument doc = new XmlDocument();
XmlNode declaration = doc.CreateNode(XmlNodeType.XmlDeclaration, null, null);
doc.LoadXml(xmlDS);
doc.Save(Response.OutputStream);
That is my code so far... not sure how to set a child node to become a parent node
i want to generate the output of an asp.net page by reading a text file, get the controls out of the text, change te properties of these controls, render it and displaying it.
so for example, the text file may contain:
<head>
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<sys:Label ID="Label1" runat="server" Text="empty1"></sys:Label>
<sys:Label ID="Label2" runat="server" Text="empty2"></sys:Label>
</div>
</form>
</body>
</html>
after reading the text, i would like to change the properties of the sys:label controls. After that, the text will be rendered, and displayed.
This has got to be easy, but has got me stumped.How do I change an element on screen several times in one function?I want to change a label to read something like "starting..." at the beginning of my function, then go away and do some stuff and then change the label to "finished" at the end.
errorMessage.Text = "Three...";
System.Threading.Thread.Sleep(1000);
errorMessage.Text = "Two...";
System.Threading.Thread.Sleep(1000);
errorMessage.Text = "One...";
System.Threading.Thread.Sleep(1000);
errorMessage.Text = "Go!";
System.Threading.Thread.Sleep(1000);
I got a asp: label (hidden by css) to which I store something.
I could not use a hiddenfield since you cannot set a css class on it. I need a css class so I can select it in jQuery. I cannot select by Id since asp.net webforms change your id. I cannot use xxxxx.ClientId, since my jQuery script isn't on that form (oh oh, i miss my mvc)
Anyhow, I pop up a dialog, let the user type sth in. When the dialog closes, I set that label to whatever the use typed in the dialog. That work (I'm testing for now using some alerts) but when I add a button, and in it's click event check the value of taht label, it is still what it originally have been though.
Here is the content of my usercontrol (at run time add as many as needed of them to my view):
Code:
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="DisputeEntry.ascx.cs" Inherits="TimeSheetDispute.DisputeEntry" %>
<p class="field switch">
<asp:label runat="server" class="disputeReason" ID="disputeReason"></asp:label>
[Code] ....
And in my page, the code that deal with it:
Code:
// Brings up a jQuery UI Dialog containing a textarea to which the user can enter a dispute
// Upon close, place that reason in the hidden input we keep for each date.
function GetDisputeReason(parent) {
var disputeReasonElement = $('.disputeReason', parent);
var existingDispute = disputeReasonElement.val();
var win = $('<div><p>Enter your reason for dispute:</p></div>');
var userInput = $('<textarea style="width:100%">' + existingDispute + '

I've been watching a video on Scott Hanselmnn teaching MVC 2 tricks/tips. He mentions how MVC 2 by default uses ASP.NET Web Forms view engine to render the output of the views; he mentions that the web forms view engine is a little slower than it could be for MVC 2 since it generates a control tree and then outputs the HTML to the page (I hope I said that right).
I was wondering what he meant by web forms generating a code tree before outputting the HTML to the page. Does anyone have insight on the view engine of Web forms and the steps of the rendering process works for ASP.NET and MVC2?

I have a nested gridview (gridview within gridview) that I need to render beneath the outer gridview.
I keep finding examples online of showing a nested gridview in the last column of the outer gridview but I need to show my nested gridview instead under the outer gridview.
I was certain that I had done this before by putting a row (<TR>) inside the TemplateField so that the nested gridview would display under the outer gridview. I am getting the data ok for the nested gridview, that is not a problem. The only issue I am having is making the inner gridview display under the outer gridview.
btw, the error is below:
<ERROR>
Type 'System.Web.UI.WebControls.TemplateField' does not have a public property named 'tr'.
</ERROR>
I'm looking at an asp.net application, i notice that there are assemblies defined into two places. In web.config there is configuration/system.web/compilation/assemblies/add elements. In the project file there are references setup under the Project/ItemGroup/Reference elements.
I was wondering, what is the difference between assemblies/references added in either location?
Is there a way to retrieve values from the form object using the id element instead of the name element?
View 3 RepliesI have a table in ASP.Net like this.
[code]....
I want to give border line to first td element which contains the colspan and rowspan. Not to the entire row.
I have noticed that when I create a website in a network drive and use the Ajax toolkit I get :
Element 'ToolkitScriptManager' is not a known element
I also noticed that after adding the ToolkitScriptManager it doesn't add the ID in the source code, it looks like this:
<asp:ToolkitScriptManager runat="server"></asp:ToolkisScriptManager>
Is missing the ID="ToolkitScriptManager1" part.
This doesn't happen when I create the site in my local drive. Is there a workaround to this. Even if I add the missing parts, I keep getting the same error.
I would like to select an element that is in the same TR as another element I found with a selector. The selector itself: $("input[name='sMessageValue']","#messageTable") Now I have this element and got its value I would like to find a checkbox located in the same TR, i tried this as starting point : $(this).(':parent').val(). But seems not the right thing to do.
View 9 RepliesYou're making a website with ASP.NET 4.0/C#, although xml alone is suitable for this example. The site will have a site map and a default page with a menu control, as follows:Web.sitemap
<?xml version="1.0" encoding="utf-8" ?>
<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >

There is a bug in jQuery 1.4.2 that makes change event on select-element getting fired twice when using both DOM-event and a jQuery event, and this only on IE7/8.Here is the test code:
<html>
<head>
<script src="http://code.jquery.com/jquery-1.4.2.js" type="text/javascript"></script>[code].....
This causes alot of trouble for us in our application cause we use both ASP.NET-events mixed with jQuery and once you hook up a change event on any element every select (dropdown) gets this double firing problem.
I have a gridview which successfully binds to the database and gets all data. Now I have added a link button in one of the coloumns which does this:
GridViewRow grow = gvInbox.SelectedRow;
DataRow dr = ((DataTable)this.gvInbox.DataSource).Rows[grow.DataItemIndex];
int MessageId = (int)dr["MessageId"];
Response.Write(MessageId);
Basically I am trying to get the datarow and get a MessageID. However the second line from above gives me outofbound exception.
Element 'content' is not a known element. this can occur if there is a compilation error in the website, or the web.config file is missing.
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<asp:Content --- showed a green wavy line , and on hover displayed the above error.
Now I am having certain problems.
1. Visual Studio 2010 hangs when I try to use ToolBox.
2. Intellisense for asp.net controls is not working.
I have tried replacing web.config file (frm backup) , tried to debug - it doesnt show anything.
All other websites are working alright. Have problem with only one of the websites.
I upgraded from VS 2008 to VS 2010 and now the AJAX elements are not recognised by the source code editor, e.g. UpdatePanel, ScriptManager, etc. I get warnings in VS and no intellisense for those elements. When I run the site, all the AJAX controls work OK though.

I have 3 columns in a GridView. The first is a templatefield with a button in it and then other 2 are just plain data from the database. Currently when I try to render the HTML from the GridView I see all 3 columns, but I only want to see the plain data fields. I have seen the answer as:gvQuotes.Columns[0].Visible = alse;But that doesn't work for me, because I still want to keep the first templatefield column on my page.
