Re: Display Images dynamically at runtime from a web site

23-May-10 1:39

Hi,

I have search facility on my web site. I am using .NET framework 3.5 with ASP.NET C# and I would like to display an image on the page. The image i am retrieving is directly from a web site e.g http://somewebsite.com/images/image1.jpg

I am trying to use the <asp:image> control and tried to set the Image URL to the web address but it doesnt work.

I know how to display the image from a web server when using Windows Form by using system.Net and using http requests but i dont know how to go about implementing this in web site.

I would appreciate if somebody could assist me with this?

Thanks,

How are you setting the image? Setting the src property for the image tag is all that is necessary.

I am using <asp:image> control and I am setting the image URL to the web address like this:

String webURL = System.Net.HttpWebRequest.Create(Title.ImageUri.OriginalString).GetResponse().GetResponseStream().ToString()
Image1.ImageURL = webURL;

if i view the source then the src is set to this which is wrong:

img id="ctl00_ContentPlaceHolder1_Image1" src="System.Net.ConnectStream" alt="DVD" style="height:122px;width:122px;border-width:0px;margin-left: 73px" />

Any advice on the above?

Thanks,

What you are doing is assigning the ImageUrl property the type name, System.Net.ConnectStream, because you are calling ToString() on the Stream object returned from GetResponseStream(). Why did you even think this was necessary or the proper way?

Title.ImageUri.OriginalString is all you need.

HOW TO INSERT DATA FROM A TABLE IN my ASP page TO SQL SERVER DATABASE [modified]

23-May-10 12:43

Hi,

Yes your right, i only need to specify the OriginalString part. I solved the problem by using the debugger after i replied to your previous message.

When i was developing a Windows Form application I was using HTTpRequests etc and assigning the values to a picture box.

Thanks for the help.

GridView is for display. Manipulating the data and inserting or retrieving from a database is separate.

Yes. They can be done using Javascript, HTML !

There are lots of menu's (not exactly the same though, a simpler version) article in CodeProject itself. Search it, try to use the one looks fine to you. You can use, Javascript, jQuery, AJAX based menus to get it. Suit your requirement and knowledge!

Problem with declaring namespace

Eagle3222-May-10 12:21

Count number of records from a tabel and display result in a gridview column at run time.

22-May-10 12:21

Hi,

I am trying to use an External Web Service in my Web Site application i am developing. The problem occurs when declaring the namespace such as this:

using namespace.classname

Error: The type or namespace cannot be found.

Does this mean i have to put the C# class file into App_Code folder?

I was wondering if somebody could help me please in terms of replicating the problem i am facing? I am trying to use the following web service:

IMDB Web Service

I have followed the instructions but it still doesnt work. I have even copied the following code from the generated output file which you will see when you access the above URL into my global WebConfig file and it still doesnt work.

I am using .NET Framework 3.5 and VS 2008.

Thanks & Regards,

Hi I am using a gridview to display data from my table at runtime. I am new to ASP.NET.

I am not using boundfields but I am using Template fields. I specify the HeaderText and DataKeys

I am using a web service to provide me a DataSet of the chosen table and bind it to the GridView in page_load event.

I would like to count the number of records from a chosen table and display that in the Gridview.

I have written a method to return number of records by passing in a string parameter product name
but i am not sure of how to invoke the method so the value is shown in the GridView.

How could i go about doing this?

Do i need to invoke the method using Eval like this:

<asp:TemplateField HeaderText="ProductName" SortExpression="ProductName">
      <ItemTemplate>
       <%#GetRowCount(Eval(ProductName))%>
  </ItemTemplate>
</asp:TemplateField>

Would the above work?

Thanks,

Why to hit performance(and extra code!) so much when you can get the same information in the dataset of gridview along with other data?

Using webservice when you are getting data, also retrieve the count of rows in it.
Or, if you cannot do that, then before using it as a source to grid, append the count of rows to dataset and use the modified dataset as datasource of your grid. You are all set!

Hi.

I have this updatepanel, with some fields that are getting filled from an ObjectDataSource.
One of the fiels are a date, and i want this date to be marked as red (and maybe in bold) if the date is one day from today or later.

Problem is, I have no clue on how to do this, since I am new to asp.net!
So is there a way to add a method that changes this specific ItemStyle-ForeColor based on the content i get from my datalayer?

This is my updatepanel:

<asp:UpdatePanel ID="updatePanel" runat="server" UpdateMode="Conditional">
        <ContentTemplate>
            <asp:GridView Width="1200" ID="gvTasks" runat="server" OnRowCreated="gvTasks_RowCreated" 

                DataSourceID="odsTaskList" GridLines="None" AutoGenerateColumns="false" CssClass="mGrid"
                PagerStyle-CssClass="pgr" AlternatingRowStyle-CssClass="alt" OnSelectedIndexChanged="GvTasks_SelectedIndexChanged"
                DataKeyNames="ID">

                <Columns>

                    <asp:BoundField DataField="Enddate2" HeaderText="Enddate" ItemStyle-ForeColor=RED-IF-OVERDUE-EXCEEDED ItemStyle-HorizontalAlign=Center>
                        <HeaderStyle Width="80px" HorizontalAlign="Center" />
                    <asp:BoundField>

                <Columns>
            <asp:GridView>
        <ContentTemplate>
    <asp:UpdatePanel>

Thanks alot!

It does not matter in your case.

You need to use RowDataBound of GridView for this.

protected void GridView_RowDataBound(Object sender, GridViewRowEventArgs e)
{  
   DataControlRowType rtype = e.Row.RowType;   
   if (rtype == DataControlRowType.DataRow && rtype != DataControlRowType.Footer 
       && rtype != DataControlRowType.Separator && rtype != DataControlRowType.Header 
       && rtype != DataControlRowType.Pager)   
   {  
      //Logic to get the color needed to be shown    
      Calendar cd = e.Row.FindControl("myCal") as Calendar;
      //Set whatever color you need to!
      cd.ForeColor = Color.Red;
   }
}

Thanks alot for your answer, but I dont quite follow the code.
Whats up with the

Calendar cd = e.Row.FindControl("myCal") as Calendar;

And could you please paste the corresponding .aspx code for the Gridview please?

I am very grateful!

No! i wouldn't

lvq684 wrote:

You said you have a calendar inside the grid, so that line gets the calendar control to you.

Looks like you are a fresher. Would suggest you to read book first.
