Web Forms :: Dynamically Adding A Css Class?

Nov 18, 2010

I have a website built that uses master page templates. In the master page I have a simple menu in a list. This is not dynamic (yet!).

I am trying to put together some code behind to write a simple css class to one of the menu links if the Request.ServerVariables("URL") is equal to the current page URL

I have no code written because everything complains when I try to come up with something. I was thinking of doing it using a switch function but am I over complicating things?Below is the simple menu with the class I am trying to write to the link:

<div id="nav">
<li><a class="selected" href="Default.aspx" title=""></li>
<li><a href="" title="ThisPage.aspx"></li> [code]....

Dynamic - Dynamically Adding A Commandbutton?

Apr 1, 2011

I have a page with a dynamically created command button. I need to dynamically wire up a click event so I can grab the CommandArgument of the clicked button.

Button b = new Button();
b.ID = "btnTrigger2";
b.CssClass = "hiddenBtn";
b.CommandName = "lbl3";
b.Click += new EventHandler(btnTrigger_Click);

The problem is the last line - I can't wire up an EventHandler this way - I need to use the standard EventArgs instead of CommandEventArgs. There's got to be a way.


Figured I'd post the code that finally worked in case anyone else tries to do the same thing.

string tabLoadedScript = string.Empty;
string postBackScript = string.Empty;
string script = " <script language='javascript' type='text/javascript'>" + System.Environment.NewLine;
script += "function clientActiveTabChanged(sender, args) {" + System.Environment.NewLine;
int i = 0;
foreach(TabPanel tp in tc1.Tabs)
Button b = new Button();
b.ID = "btn" + tp.ClientID;
b.CssClass = "hiddenBtn";
b.CommandName = tp.ID;
b.Command += btnTrigger_Click;
AsyncPostBackTrigger trg = new AsyncPostBackTrigger();
trg.ControlID = "btn" + tp.ClientID;
tabLoadedScript += "var isTab" + tp.ClientID + "loaded=$get('" + tp.Controls[0].ClientID + "');" + System.Environment.NewLine;
postBackScript += "if(!isTab" + tp.ClientID + "loaded && sender.get_activeTabIndex() == " + i + ") {" + System.Environment.NewLine;
postBackScript += "__doPostBack('" + b.ClientID + "','');}" + System.Environment.NewLine;
script += tabLoadedScript;
script += postBackScript;
script += "}" + System.Environment.NewLine;
script += "</script>";

this.ClientScript.RegisterClientScriptBlock(this.GetType(), "cs", script, false);
protected void btnTrigger_Click(object sender, CommandEventArgs e)
Panel ctrl = (Panel) FindControlRecursive(this, "pnl" + e.CommandName);
ctrl.Visible = true;
public static Control FindControlRecursive(Control Root, string Id)
if(Root.ID == Id)
return Root;
foreach(Control Ctl in Root.Controls)
Control FoundCtl = FindControlRecursive(Ctl, Id);
if(FoundCtl != null)
return FoundCtl;
return null;

VS 2008 Adding Columns To A Gridview Dynamically

Jul 13, 2010

I have seen code for adding columns at runtime but here is another scenario for you. I am using a SQLDatasource control for my gridview. And the data returned can have different columns based on the filter meaning one time I may have a column A1, A2, A3 and another time I may have A2, A3, A4. Is there any way I can look at the columns when it is binded at the beginning and add the columns first?

I really need to use the SQLDatasource though because I am connecting to an AS400 and it is using a connection already made in the webconfig and do not know any other way. I do if it was MSSQL server but not this.

C# - Dynamically Adding A Styled Label To Web Page?

Dec 9, 2010

I have the following code which adds a label and a gridview to an asp.net page:

GridView grd = CreateGridView(kvp.Key.Text);
Label l = new Label();
l.Text = "some text";
l.CssClass = "this has no effect";

Two questions really:As the page will have a multiple and unknow quantity of Label + Grid pairs I'm looping through the above code, is this the best way to add the controls to the page?I cannot style the label? How do you do it? Looking at the HTML which is created, the label turns out to be a SPAN.

Counting Rows In C# After Dynamically Adding Them With JQuery

Dec 15, 2010

I just have a simple ASP Table seen here:

<asp:Table ID="tblCategories" runat="server" CssClass="oneColTable padded-table dataTable">
<asp:TableHeaderRow CssClass="tableHeader">
<asp:TableHeaderCell>Category Name</asp:TableHeaderCell>
<asp:TableHeaderCell Width="50">Delete</asp:TableHeaderCell>

And if the user wants to add an additional row I use the jQuery Clone method to copy and append a new row.

My issue comes when I want to count the rows present on the C# side it always lists 1 Row. The row for the header entry.

How can I correctly grab the accurate row count on the C# (Codebehind) side?

Web Forms :: Adding Multiple Usercontrols Dynamically?

Sep 21, 2010

I have a simple user control which contains a textbox and a dropdownlist. I need to add this control multiple times to my page then save the details to my db, validating each control. When they re-enter my page I need to load the user control for each record in the db populated with the data they entered. They can then edit the data, delete the row or add new rows.

I'm trying to find the cleanest most efficient way to accomplish this. I realise I would need to re-add the user controls after each postback re-populating the data. Would the best way be to add each row to an arraylist or list of type object, save it to the viewstate and re-add the controls with data on postback, or is there another method which would suit?

C# - Dynamically Adding Columns To A Table In An MVC View

Apr 20, 2010

I am returning an IList to my model of data about users. I want my end users to be able to select which columns they want to see.

I know I can do this with a huge "if statement" however, I know there must be a better way. I have created an Enum with the column names. I feel if I could take the IListItem.EnumName I would be set. However, I'm not too sure on how to do this.

Web Forms :: Dynamically Adding User Controls

Sep 5, 2010

I am new to ASP.NET And I am have THE hardest time understanding how to work with forms in ASP.NET. Here's what I am doing:

Dynamically add User Controls to a PlaceHolder based on some int value (which currently is passed in a HiddenField).Fire an event if the WebControls inside of the User Control change, then handle that event in the Main Page (i.e. save the input to DB)When the user clicks the "Next/Continue" button, the next controls for the next page are loaded. And I guess maybe I just can't seem to get how things work in ASP.NET, because I am really struggling with the general idea of how ASP.NET flows.

Should I be dynamically loading the controls in Page_Init, or Page_Load? Or should I load the controls when the buttonclick event is fired?Do I have to add the axCtrl.OnDataChange += new EventHandler(HandleAxControlDataChange); line on Page_Load? Or should I put this in When I first load the UserControl, I need to initialize some WebControls within the UserContorl. Is there a way to know if I have loaded new user controls into my placeholder? I can't use Page.IsPostback, because after the first page, every page is a postback from the buttonclick.

Here's what I have:


Here's the markup from my ASPX file...
