I have developed an application in asp .net 2.0 using c# with code-behind.
I found that I was unable to use design mode in VS2005 for my pages subordinate to the master page as whenever I switched to design mode I saw only the master page rendered but greyed out - i.e. none of the subordinate page's controls or content were rendered. I therefore had to resort to editing the raw html in every case. Any user controls which I created showed up correctly when viewed in design mode in isolation, though.
There's nothing wrong with the overall design of the application as it generates valid html for Firefox and IE.
Anybody know of an obvious reason for this? I feel it must be something simple.

Hello friends..
I am facing one problem with requiredfieldvalidator .My .aspx page contains top, bottom and left web user controls. The middle part of the page contains some textboxes and requiredfield validator associated with them. Left control displays some menus. I use link button to display links on the left control. Now, whenever i click on the link buttons the requiredfiledvalidator displays error because the textbox is empty.The important fact is that both linkbuttons and requiredfieldvalidator lies on same page. How to avoid this?

Set the CausesValidation Property of the LinkButton to false.

I am getting the following error when am adding a table in my page.
Validation(XHTML 1.0 Transitional): Attribute 'height' is not a valid attribute of element 'table'
Validation(XHTML 1.0 Transitional): Attribute 'width' is not a valid attribute of element 'tr'
Validation(XHTML 1.0 Transitional): Attribute 'height' is not a valid attribute of element 'tr'
My Code as follows.
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="AdminLogin.aspx.cs" Inherits="Admin_AdminLogin" %>
<%----%>
<title>Test
I commended the second line eventhough still getting these errors.

Is this actually preventing you from compiling the site? These are XHTML validation errors that simply mean that the XHTML 1.0 Transitional specification doesn't recognize those attributes as valid for that element. It shouldn't prevent you from being able to compile and run the site.

You can use Item template for inserting a dropdownlist in the datagrid .
<Columns>
<asp:TemplateColumn HeaderText="Action">
<ItemTemplate>
<asp:DropDownList id="DDAction" runat="server" Visible="False" OnSelectedIndexChanged="DropDown_SelectedIndexChanged"
AutoPostBack="True"></asp:DropDownList>
</ItemTemplate>
</asp:TemplateColumn>
</Columns>
Now , when selected_index_changed event of dropdownlist fire, that time i want to
know that at which row index dropdownlist is.
Now in the code behind write the following code.
protected void DropDown_SelectedIndexChanged(object sender, EventArgs e)
{
DropDownList list = (DropDownList)sender;
if(list.SelectedItem.Text==".......";
.....
//To get the corresponding row
TableCell cell = list.Parent as TableCell;// getting the parent cell of dropdown
DataGridItem item = cell.Parent as DataGridItem;//getting the parent of tablecell ie the row
string p_key=item.Cells[2].Text.Trim();//getting the column values of the row
........
Tickle your brain and the ideas are out

Impossible, without knowing the structure of your database. Presumably it would take the selected item from the first list and pass it into a database call to get the relevant second list.
The book 'AJAX in Action' has an excellent sample which can be used to do this with AJAX. It's a prime candidate IMO for a place where AJAX adds a lot of value.

Dear All,
I need a Regular Expression to validate a date
in yyyy-mm-dd at Server Side.
Any help will be greatly appreciated.

The program Expresso is great for learning/testing regex, it's easy to find with google. In this case, it's just
\d{4}-\d{2}-\d{2}
assuming you want to force the format you showed ( i.e. not accepting 2007-12-2 or 2007-2-12 )
If you want to accept those values, it's
\d{4}-\d{1,2}-\d{1,2}

how to Make a Project in ASP.net Which will capture Image by Using a Webcam?
May we add a part of an individual project in to our application ? if we have only EXE of that Project
|
|
|
|
|
to capture a webcam, you'll need to write the code as a browser plugin, which means your users need .NET installed ( if you use C# ) and will need to trust your site enough to allow your code to run on their machine. This is not likely to work unless you are dealing with users who already trust you.

create an instance of field type that you want to add in your gridview.
For eg,If you want to create a buttonfield, create an instance of buttonfield.
Dim col1 As New ButtonField
Next set the basic properties for that instance.
col1.HeaderText = "ButtonColumn"
col1.ButtonType = ButtonType.Button
col1.Text = "Click"
Add that instance to your gridview
GridView1.Columns.Add(col1)
with regards,
lavanya

i was trying to populate the dropdownlist in the following manner.
objclsdb.BindingWithControl(this.DropDownList1, "ItemID", "ItemName");
2nd parameter is value member
3rd member is display member
public string BindingWithControl(DropDownList ctl,string ValueMember,string DisplayMember)
{
ctl.DataTextField = DisplayMember;
ctl.DataValueField = ValueMember;
ctl.DataSource = ds;
}
but the code is not populating the dropdonlist.
code for dataset is not mentioned .
because it is working.

ctl.DataBind(); at the end of your function.
