When I create a new MVC view page this what the top of the page lookslike:
<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage" %>
There is no code behind attribute. What am I doing wrong?
|
|
|
|
|
on ASP.NET MVC the Code Behind class was replaced by Controller class, each view has a Controller
|
|
|
|

I want to replace a specified subString is a string by javascript.
I don't know the exact substring part, just I know it starts with <layer>
Best wishes

The string object in JavaScript has a replace method, so if you need to do more than a simple replace then we'd need some details.
From http://www.w3schools.com/jsref/jsref_replace.asp[^]:
Syntax
stringObject.replace(findstring,newstring)
Parameter Description
findstring Required. Specifies a string value to find. To perform a global search add a 'g' flag to this parameter and to perform a case-insensitive search add an 'i' flag
newstring Required. Specifies the string to replace the found value from findstring
If you need to simulate the .startsWith function in JavaScript then here's an article that demonstrates how to do so using regular expressions:
http://www.tek-tips.com/faqs.cfm?fid=6620[^]
If you need to do something different then let us know.

Hi, In my project I want to bind the datetime with link button in the Repeater. I print the datetime in the Repeater using Convert(varchar,cre_date,107).It It is displaying in the format of Feb 23,2009 . But it is conflicting with the Html coding of
<asp:linkbutton id="lnldat" text="<%# Eval(" cre_date=")%>" runat="server" xmlns:asp="#unknown"> .
How to display the date in that format with Link button? Can anyone help?

Use the repeater's onitemdatabound event.
Add the OnItemDataBound="Repeater_ItemDataBound" to the mark up of the repeater.
Add the following to your code behind with modifications...
protected void Repeater_ItemDataBound(Object Sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item | e.Item.ItemType == ListItemType.AlternatingItem)
{
LinkButton lnldat = (LinkButton)e.Item.FindControl("lnldat");
DataRowView dataRow = (DataRowView)e.Item.DataItem;
lnldat.Text = dataRow["YouColumn"].toString();
}
}
I didn't get any requirements for the signature

An error occured like this?
Unable to cast object of type 'System.Data.Common.DbDataRecord' to type 'System.Data.DataRowView'.
What is datarowview?

I wrote the coding like this.
protected void Repeater_ItemDataBound(Object Sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item | e.Item.ItemType == ListItemType.AlternatingItem)
{
LinkButton lnldat = (LinkButton)e.Item.FindControl("lnldat");
DataRowView dataRow = (DataRowView)e.Item.DataItem;
lnldat.Text = dataRow["cre_date"].ToString();
}
}
And i got the error
Unable to cast object of type 'System.Data.Common.DbDataRecord' to type 'System.Data.DataRowView'.
when the form is load?

My fault. If you use a datatable the object is datarowview. If you use a datareader the object is dbdatarecord. just replace datarowview with dbdatarecord.
protected void Repeater_ItemDataBound(Object Sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item | e.Item.ItemType == ListItemType.AlternatingItem)
{
LinkButton lnldat = (LinkButton)e.Item.FindControl("lnldat");
dbdatarecord dataRow = (dbdatarecord)e.Item.DataItem;
lnldat.Text = dataRow["cre_date"].ToString();
}
}
I didn't get any requirements for the signature

It has the following error..
The type or namespace name 'dbdatarecord' could not be found (are you missing a using directive or an assembly reference?)
|
|
|
|
|
System.Data.Common.DbDataRecord
I didn't get any requirements for the signature
|
|
|
|
|
The following error came?
The type or namespace name 'dbdatarecord' could not be found (are you missing a using directive or an assembly reference?)
Where to add this line? Please explain briefly?

replace dbdatarecord with System.Data.Common.DbDataRecord

Hi all, I have the same question here. I am trying to build a chat application for my webpage. What i need to do have is implement private chat. So far i have done the chat application using a database and using a timer which checks every 3-5 secs to refresh the messages.
My question is :
I need to eliminate the use of timer and want to implement it as a condition. i.e only if the user enters a chat into the box should the other person refresh his text box and it shouldnt be run on a timer. Is it possible? Please help.

I didn't get your problem. If your control is inside the Updatepanel, then that part will take part in the post back. Then what is your problem ?

Why did you make UpdateMode="Conditional" ? .
Did you call UpdatePanel1.Update() from any where of you code ?
If you change the UpdateMode from Always to Conditional, you need to call Update() method Explicitly for Update that Panel. And I think this is the reason .
Try to Make it "Always" Or if you don't need it to postback always, Just call UpdatePanel1.Update() while Paging and Sorting from Codebehind. That will resolve your problem.
