findcontrol

I have used FindControl in the past, prior to .NET 2.0/3.0. It seems like now, for some reason, the ID's of my controls get a funky named assigned. For example I assigned an id "cbSelect" to a checkbox, but FindControl does not find it. When I view the HTML it was assigned ctl00_bodyPlaceHolder_ctl02_cbSelect . I have not found one example of FindControl that mentions that. In fact everyone seems to just use find control like normal. So, am I doing something wrong? Did .Net change? Can anyone shed some light onto this for me, it is really frustrating! You are probably using a MasterPage or

I have to find a Control in an aspx page bound to a master page. The master page contains: <asp:ContentPlaceHolder ID="MainContent" runat="server"/> The content page contains: <asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" Runat="Server"> </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" Runat="Server"> </asp:Content> I added a Table with ID formtable as a child of Content2 . I tried to use the following code to access the Table , but the code returns null : protected void Ok_Click(object sender, EventArgs e) { Table tblForm = this.FindControl(

Existed MyControl1.Controls.OfType<RadioButton>() searches only thru initial collection and do not enters to children. Is it possible to find all child controls of specific type using Enumerable.OfType<T>() or LINQ without writing own recursive method? Like this . I use an extension method to flatten control hierarchy and then apply filters, so that's using own recursive method. The method looks like this public static IEnumerable<Control> FlattenChildren(this Control control) { var children = control.Controls.Cast<Control>(); return children.SelectMany(c => FlattenChildren(c)).Concat(children

I currently have a dropdown inside an ascx control. I need to "find" it from within the code behind on another ascx that is on the same page. It's value is used as a param to an ObjectDataSource on ascx #2. I am currently using this ugly piece of code. It works but I realize if the conrtol order were to change or various other things, it wouldn't be where I am expecting. Does anyone have any advice how I should properly be doing this? if(Page is ClaimBase) { var p = Page as ClaimBase; var controls = p.Controls[0].Controls[3].Controls[2].Controls[7].Controls[0]; var ddl = controls.FindControl(

This question already has an answer here: Better way to find control in ASP.NET 8 answers I'm sorry, but I can't understand why this doesn't work. After compile, I receive a "Null reference exception". Please help. public partial class labs_test : System.Web.UI.Page { protected void Button1_Click(object sender, EventArgs e) { if (TextBox1.Text != "") { Label Label1 = (Label)Master.FindControl("Label1"); Label1.Text = "<b>The text you entered was: " + TextBox1.Text + ".</b>"; } } protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e) { Label Label1 = (Label)Master

I was wondering how one would find the controls in the HeaderTemplate or FooterTemplate of an Asp.Net Repeater control. I can access them on the ItemDataBound event, but I was wondering how to get them after (for example to retrieve a value of an input in the header/footer). Note: I posted this question here after finding the answer just so that I remember it (and maybe other people might find this useful). mbillard As noted in the comments, this only works AFTER you've DataBound your repeater. To find a control in the header : lblControl = repeater1.Controls[0].Controls[0].FindControl(

Hi i have few a single textbox within the the datatemplate for itemscontrol. When i bind the itemcontrols to a observable collection i get two text boxes. But i need to do some manipulations based on each of the text boxes for which i want to find each textbox seperatly using some id. Can anybody help on how to find a control witin the itemscontrol in WPF. Using the ItemContainerGenerator you can obtain the generated container for an item and traverse the visual tree downwards to find your TextBox. In the case of an ItemsControl it will be a ContentPresenter, but a ListBox will return a
