The regular expression "\d{2,}" will match any sequences with two or more digits.

Hi,
Firstly:How can I get MessageBox in ASP.Net Page by using C#.When I am Using Response.Write("alert('Employee ID already Exits');"); Font of my Label's in the ASP.Net page getting changed...
Secondly:I am using Microsoft Access as my Back end.Their I created an Employee table and I am Inserting ,Updating and Deleting the records of that table.Created EMPLOYEE ID as primary key.
What I trying to get is that when I am trying to Insert a Duplicate record (i.e Same Employee ID which is already present)a message Box Show that Record already present.
Regards.,
Deepak

That's because you are writing out the code before the code of the page. That makes the browser ignore the doctype tag and render the page in quirks mode.
Use the Page.ClientScript.RegisterStartupScript method to put the script in the page.

Either check for the id before you add the record, or handle the exception that is the result of trying to add a duplicate id.

I have one form. When I took the Form to ReadOnly state all the controls in the form are need to be in readonly,
A) I have Gridview. How to make this Gridview to ReadOnly. Currently I am doing the gridview.enabled = false. It greyed out the gridview.
B) And I have some validation controls, I want to supress that validations when the form is in Readonly.
Thanks

A) You have to Navigate through the control Collection of the Gridview and set the property to Read-Only/ENABLED-False.
B) You have to set the Enabled property of the validation controls to false. Page has GetValidators("group") method. Check whether this helps you in some way to disable all the validation controls at once, since it returns the validators to the ValidatorCollection object.

You can't do that unless you understand the Basic's of SQL. I would reccomend you to go through the Basic's Of SQL Commands.[^]

Database doesn't have rows. Only tables in the Database can contain Row's. what is that you are trying to do exactly in that code?
I have sent you a link to Read the Basic's of SQL Command. If you go through it you will understand how to write a UPDATE statement in SQL.

sorry !! i mistyped it !!! i actually wanted to update a row in table.. i have a data grid with few columns in it . I want to edit each row and update it . when i try to click edit button it shows an exception (Invalid Operation) . Hope u got it now..

Here is the syntax of the UPDATE statement used to make changes to the existing records in table.
update tablename<br />
set columnname = newvalue [,columnxname = newvaluex...]<br />
where columnname OPERATOR value [and|or columnnamex OPERATOR valuex]
Compare this syntax with your UPDATE statement and check whether you have given it right.

Dear Friends,
How we can keep data after inserting in formview controls?.
When i'm inserting a record formview will fire a method, that method is calling a stored procedure. If Stored Procedure is return error i want to keep data in my formview.
How i can solve this issue?

I think having the ViewState Enabled for ur control should solve this problem
try having the EnableViewState=true in ur FormView
or save that record in the session and take it back on return
I hope it helps

I am using the Ajax control toolkit TabContainer.
When I place it on the page in design view instead of seeing the Tab control I see a little brown box.
I looks fine when I run the page - it just doesnt display how it will look in the design view.
Am I doing something wrong or is it supposed to be this way ?
Thanks

Hello everyone,
well I'm working in a module where i'm using a gridview to display data without binding it to it. Now its working but the only problem is that it doesnt sort in alternating ASC/DESC order like normal. I noticed while debugging that I was always getting the SortDirection in the OnSorting event as Ascending.
Is there some other way so that I can make the sorting in the usual Alternating way of ASC and DESC.
Hope u got what I'm saying 
<asp:GridView ID="GridView1" runat="server" PageSize="20" DataKeyNames="DirectoryID" AutoGenerateColumns="False" AllowPaging="True"
OnPageIndexChanging="GridView1_PageIndexChanging" OnRowUpdating="GridView1_RowUpdating"
OnRowDeleting="GridView1_RowDeleting" AllowSorting="true" OnSorting="GridView1_OnSorting"
OnRowCancelingEdit="GridView1_RowCancelingEdit" OnRowCommand="EditButton_OnRowCommand">
<Columns>
<asp:TemplateField SortExpression="DirectoryID" HeaderText="DirectoryID" Visible="false">
<ItemTemplate>
<asp:Label ID="Label_ID" Text='<%# Eval("DirectoryID") %>' Runat="Server"/>
</ItemTemplate>
</asp:TemplateField>
...
and in the On sorting event I'm doin this
protected void GridView1_OnSorting(object sender, GridViewSortEventArgs e)
{
DataView dv = (DataView)Session["dvVD"];
if (dv != null)
{
//Vendor_Directory vd = new Vendor_Directory();
dv.Sort = e.SortExpression + ((e.SortDirection == SortDirection.Descending) ? " DESC": " ASC");
GridView1.DataSource = dv;
GridView1.DataBind();
}
}
Thanks in advance
Rocky

This article[^] says that Gridview seems to have problem when we do sorting. The Value of SortDirection is always set to "Ascending". But the problem is sorted out having the sort Direction and Sort Expression in the Viewstate. Have a look, it may help you to solve the problem.

Yeah. You can show the embedded object in your aspx page but you won't be able to control the functionality of this media embedded object.That means you can't play/stop/pause the movie from code. All you can do is that you can show the different embedded media object according to what the user wanna see..

|
|
|

Hi,
Ok.control is not problem...I need to know some brief coding for this...I want to play the movies dynamically..Please help me to solve.
