Hi,
I am working on mobile applications but I am using the selection list inside the Mobile web user control and use the list to navigate between pages. for instance, my selection list will contain the number of pages and if I select one page my form has to get the second page results. I added a SelectIndexChanged event to navigate to other page but its not hitting the event at all. Could anyone please tell me. I am having the selectionlist in the code behind file of my user control.
the user control and the form that I insert my user control like this;
UserControl.ascx
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="PagingMenu.ascx.cs" Inherits="PagingMenu" %>
<%@ Register TagPrefix="mobile" Namespace="System.Web.UI.MobileControls" Assembly="System.Web.Mobile" %>
<mobile:panel id="pageMenu" runat="server" paginate="True">
Code behind of user control
protected override void OnPreRender(EventArgs e)
{
RenderTheContent();
base.OnPreRender(e);
}
public void RenderTheContent()
{
int _noOfPages = 1;
for (int i = 0; i < Request.QueryString.Count; i++)
{
if (Request.QueryString.GetKey(i) != "pi" &&
Request.QueryString.GetKey(i) != "pfn" &&
Request.QueryString.GetKey(i) != "actn")
{
Query += "&" + Request.QueryString.GetKey(i) + "=" + Request.QueryString[i].ToString();
}
}
if (Query.Length > 0)
{
Query = Request.Url.LocalPath + "?" + Query.Substring(1);
}
else
{
Query = Request.Url.LocalPath + "?";
}
// Gets the values from Query String
if (Request.QueryString["pi"] != null && Request.QueryString["pi"].ToString().Length > 0)
{
PageIndex = Convert.ToInt32(Request.QueryString["pi"]);
}
// Calculating number of pages
if (Total % PageSize > 0)
{
_noOfPages = Convert.ToInt32(decimal.Floor(Convert.ToDecimal(Total) / Convert.ToDecimal(PageSize))) + 1;
}
else
{
_noOfPages = Convert.ToInt32(Convert.ToDecimal(Total) / Convert.ToDecimal(PageSize));
}
slist = new SelectionList();
slist.SelectType = ListSelectType.DropDown;
//slist.SelectedIndexChanged
MobileListItem li = null;
string valueString = "";
for (int i = 1; i <= _noOfPages; i++)
{
valueString = "";
li = new MobileListItem(i.ToString());
for (int j = 0; j < Request.QueryString.Count; j++)
{
if (Request.QueryString.GetKey(j) != "pi")
{
valueString += "&" + Request.QueryString.GetKey(j) + "=" + Request.QueryString[j].ToString();
}
}
valueString = "?pi=" + i.ToString() + valueString;
li.Value = valueString;
slist.Items.Add(li);
}
slist.SelectedIndex = PageIndex - 1;
pageMenu.Controls.AddAt(0,slist);

well from your code I couldn't understand where and how your are adding the event handler to the dropdownlist. You have to add the event handler to the dropdownlist, you can do it in multiple ways one of them is to do in the aspx page like
<asp:dropdownlist id="ddl" runat="server" onselectedindexchange="ChangePage"></asp:dropdownlist>
do this and see if it helps

How come that almost every time someone post about something "very strange", it is not strange at all... 
The site is using cookie-less sessions, which puts the session id in the url.
Experience is the sum of all the mistakes you have done.

you can disbale the client-side caching using the following code
Response.Cache.SetCacheability(HttpCacheability.NoCache)

Hi,
Thnaks for your reply....but i didn't get the result...please help me...
The code that you gave is put it in my timedout.aspx page...is that ok....
regards
alex.

|

You can put that in a common base class(if you have one in your application) which is inherited in all the page so that client-side caching will be disabled for the whole application. or you can put in the page that you don't want to cache on the client-side.

Hi,
I'm writing some excel data to dataset(asp.net 1.1 with c#). In one of the columns of the excel has both numeric and alphabetic characters. While reading it is reading only numeric ones, whereas alphabetic are going as null. So I modified the connection string as follows:
strConnectionString="Provider=Microsoft.Jet.OleDB.4.0;Data Source=" +strFolder+strFileName+";Extended Properties=Excel 8.0;HDR=NO;IMEX=1";
When I done this, I'm getting the error 'Couldn't find installable ISAM Driver'. I have made necessary changes in registry also. I have googled about this error and got some info from Microsoft site. But even after doing all these, issue still persists.
(i) Any idea how to resolve this issue?
(ii) Or is there any other way I can read both the numeric and alphabet characters to the dataset?
Any help in this regard would be great.
Thanks

I am displaying some information using a datagrid, one of the columns is a date column.
The date displays but it also displays the time like this 15/11/2007 00:00:00.
Is there anyway to get rid of the time protion and just disply the date?
Thanks,
macca

If it's a BoundColumn then you can set the DataFormatString property of the column to {0:dd.MM.yyyy}

Try following code
Text='<%# Eval("DateField","{0:dd:MM:yyyy}")%>'

Hi everyone,
Im going to do an application where i store some video files in a folder.And in my form i list out them.Need to play selected video in the browser..
Anyone has got idea on how to play a videofile in browser?
Thanks in advance... (
|
|

The easiest way is that upload your file to some videos sites and get the embedded code and use it in your webpage.. (Like posting the Youtube video on your blog)
If you don't want to upload your video file to those video sites, you can probably use Windows Media service or etc.. but if your site is published on ASP.NET host, you should contact with your hosting service provider for asking whether they support the Media Streaming Service or not. AFAIK, there are some hosting companies that doesn't support the Media Streaming Service to the Shared Host customers... If your hosting support the media streaming then they will have the documentation about how to upload the video files and how to display in your website... Actually, we can't give you that much advices since the way of doing this might be differ from one hosting to another for the shared host users.
If you wanna test the Video steaming locally, you can google about this.. asp.net video streaming

Hi All...
I am using webparts and i have defined a verb and assigned it a client side event as its handler.
Now i want to close this webpart using its id at clientside. I am giving the script im using to set its display to none. But it is not sufficient. I want to close it.
function ClientClose(webPartID)
{
alert( "You clicked the following web part: " + webPartID + "." ) ;
document.getElementById(webPartID).style.display="none";
}
Bye
