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.

I have one gridview control with two hidden fields and one dropdownlist.
AutoPostback property of dropdownlist is true.

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
........

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.

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 Capture image

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
Confused | :confused:

Re: How to Capture image

Christian Graus29-Sep-07 1:03

Christian Graus

29-Sep-07 1:03

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)

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;
