Hi,
How can I find all textbox in a form at runtime?
Thank you 
|
|
|
|
|
By iterating over the controls collection of the form and check each control to see if it's a textbox
foreach(Control control in Controls)
{
TextBox tb = control as Textbox;
if (tb != null)
{
tb.Text = string.Empty;
}
}
An ASP.NET app would require a recursive solution.

May still need to do a recursive for container such as panel, tablelayout, group, etc.
<br />
protected virtual void UnbindControls(Control control)<br />
{<br />
foreach (Control obj in control.Controls)<br />
{<br />
if (obj is Panel)<br />
{<br />
UnbindControls(obj);<br />
}<br />
else if (obj is GroupBox)<br />
{<br />
UnbindControls(obj);<br />
}<br />
else if (obj is TabControl)<br />
{<br />
UnbindControls(obj);<br />
}<br />
<br />
<br />
if (obj is TextBox)<br />
{<br />
}<br />
}<br />
}<br />

{
TextBox TryTest = new TextBox();
Button btn = new Button();
TryTest.Font.Bold = true;
TryTest.ID = "Text1" ;
btn.ID = "Btn1";
btn.Attributes.Add("runat", "server");
btn.Attributes.Add("OnClick", "Button1_Click");
btn.Attributes.Add("Text", "Press Button");
PlaceHolder1.Controls.Add(new LiteralControl("
"));
TryTest.Text = "";

PlaceHolder1.Controls.Add(btn);
PlaceHolder1.Controls.Add(new LiteralControl("
"));
}

This is not the ASP.NET forum.
You have to add your control before the page load event, in order for it to exist when viewstate is restored. Otherwise, your control is not there, and the viewstate is lost, including events.

If you add OnClick as an attribute, it will just end up in the client code. It's only when you write it in the markup code that it is compiled into code that binds the event handler.
When you create the control dynamically, you have to write the code that binds the event handler yourself:
btn.Click += new EventHandler(Button1_Click);
The runat and Text attributes are also only used when you write the control in the markup code. If you add them as attributes, they will end up unchanged in the generated html code, where they have no meaning at all. Use the Text property of the control to set the text:
btn.Text = "Press Button";

i know it is simple but i am hang , i have an string to search in string i have to search digits and spe cial characters and alphabets how can i put condition in c Sharp in if condition.
i have use it before but now i forget the way how to search in a string.
|
|

|

Try using the Char class. It has some static functions that check if your character is a digit, letter and so on:
foreach (char c in s.ToCharArray())
{
if (Char.IsDigit(c))
{
Console.Write();
}
}

You can use the Contains method of the strng class, or for more complex searches, use regular expressons, for example, you can use \d to search for any digit in a string, using regex.

//do something
}
else
{
//do nothing

Wow, after three decent answers, you felt the need to post this ? It's really a messy way to go.
M. Ahmed wrote: for(int i=0; i<=email.Length - 1;i++)
Why not just i < email.Length ? Why not just foreach (char c in email) ? Why not store your special chars in an array, so the code is maintainable, or just use regex ?

I am establishing the COM Interoperability where I'm exposing the functionality in my .net component to client developed in either vb 6.0 or vc++.
I don't have any issue regarding how to implement the COM Interoperabiliy. My problem is, to make my call from client to .net component successful, I have to put my client application also in the same path where my .net component is. If I put my client application in a path other than my .net component path then call is not successful as it fails to find out some DLL dependancy. Can someone tell me how I can run my client application independent from the .net component path.
I hope I'm clear with my question. Thanks & Regards,

If your DLL is a COM dll, then it should register as such, and run from where-ever you like. Are you calling it from C++ or VB6 ? What is the dll it cannot find ?

My dlls are not COM dll so I'm not registering them with registry. I have a .net component (dll) which can be accessed through COM interop by VB or VC++ client. my .net component is using some dlls so at the runtime (i.e. during client call these dlls could not be found)
|

|

OK, well, it doesn't sound to me like you're using COM interop at all. Where does COM come into it, if you're not writing COM dlls ?

I think we are not talking on the same line. Let me elaborate.
I have a .net application and some of the functionality of this application I have exposed through a dll. I have used COMVisible attribute to expose the functionality in this dll to other application. I register this dll with registry using regasm tool (and not through regsvr32 or something.... that's why I said I'm not registering the dll with registry). Now client developed in VB or VC++ can use this dll (registered as COM with registry) to consume the functionality exposed by my .Net application.
When I put my client application in a path other then my .net component path it fails to find out the path for the dependency dlls.
I hope now question is clear. Sorry for replying to your question is hush hush...

OK, spot the contradiction.
If your DLL is COM, it's in the registry and you can put it anywhere. It may still need some dlls ( it sure needs the .NET framework ), and that could be your issue. Hard to say, based on the level of detail you've provided ( I did ask once about the dlls it needs, but you did not give a specific reply )

the COM interop dll is also using some dlls developed as part of our application. so it is failing to find these dlls n not the .net framework dll.
What i have done is I have put codebase entry in my registry along with dll registration. So i think it finds the COM Interop dll but com interop dll in turn fails to get the dependancy dlls.
hope things are clear now. If not pls revert back for more clarification. Thank you very much for your persistent support. I really appreciate it.

Hello,
I'm having a problem Serializing/Writing the objects that were initially generated by xsd.exe and then extended (by adding attributes) via partial class. Since it will be hard to read if I paste all my code, I'll try to explain it instead.
XSD generates classes from the schema. IN my case let's call them:
public partial class ParentClass {}<br />
public partial class ChildClass {}
All of these are generated inside a DataModel.cs class.
So I created another DataModelEx.cs class where I added the following:
public partial class ParentClass<br />
{<br />
private string dataRootField = string.Empty;<br />
<br />
public string DataRoot<br />
{<br />
get { return dataRootField; }<br />
set { dataRootField = value; }<br />
}<br />
}<br />
<br />
public partial class ChildClass1<br />
{ private ParentClass parent = null; }
Adding these, when I try put values in the class and serialize it, this is the error that I am getting:
Error: There was an error reflecting type 'NAVITAIRE.SkyPlan.utility.data.DirectorySettings'.<br />
at System.Xml.Serialization.XmlReflectionImporter.ImportTypeMapping(TypeModel model, String ns, ImportContext context, String dataType, XmlAttributes a, Boolean repeats, Boolean openModel)<br />
at System.Xml.Serialization.XmlReflectionImporter.ImportElement(TypeModel model, XmlRootAttribute root, String defaultNamespace)<br />
at System.Xml.Serialization.XmlReflectionImporter.ImportTypeMapping(Type type, XmlRootAttribute root, String defaultNamespace)<br />
at System.Xml.Serialization.XmlSerializer..ctor(Type type, String defaultNamespace)<br />
at System.Xml.Serialization.XmlSerializer..ctor(Type type)<br />
at NAVITAIRE.SkyPlan.utility.Util.WriteDataToXml(String outputFile, Object data) in C:\workspace\PlanningSuite_Local_Dev\gui\src\utility\Util.cs:line 1741
My guess is that I may be missing some tags like the following in declaring my attributes:
[System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "2.0.50727.42")]<br />
[System.SerializableAttribute()]<br />
[System.Diagnostics.DebuggerStepThroughAttribute()]<br />
[System.ComponentModel.DesignerCategoryAttribute("code")]<br />
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType=true)]<br />
[System.Xml.Serialization.XmlRootAttribute(Namespace="", IsNullable=false)]
I am not familiar about these [] tags before declarations, so please help me out. I tried experimenting by placing some [System.Xml.Serialization.XmlIgnore()] before the new properties but it didn't seem to work, or maybe I just placed them incorrectly.
Thank you for your help!
Sincerely,
Rafferty

Nasty problem.
Make sure your class is marked with [Serializable]. Certain complex types cause problems too I believe. Dictionary<> and the sort. Try putting [XmlIgnore] infront of these (which will prevent serialisation) and see if that helps, you may have to use more primitive types if that helps.
[DebuggerStepThroughAttribute] prevents the debugger from stepping into the generated code, not always that helpful so just find and replace these with an empty string may help with debugging.
Regards,
Rob Philpott.
