In your project. Right click and select "Add Reference..."

A dialog will pop up (usually after some seconds - It is quite slow at starting)

In the .NET tab look in the list for System.Web or System.Security (what ever you are trying to add) and hit Okay.

Which time out you want to avoid. It can be at multiple levels i.e. Web Server (IIS), SQL or if its more complex infrastructure than at firewall level.

I maybe too late to reply this post, but hope to help others who meet similar problem on solving this.

I fixed this but putting the popup panel into another panel and set the display style to "none".

<asp:Panel runat="server" ID="container" style="display:none" >
<asp:Panel runat="server" ID="popupPanel" >
.....
</asp:Panel>
</asp:Panel>

Change what is rendered when dragging a webpart

Hi all

I have a web page with a number of webparts which I have created (as in inherited from Webpart not just web controls in a zone) in a zone I have created along with a created chrome. They all work fine!

The problem is that they contain a lot of information and I have noticed that when you try to drag a webpart you need to wait a little while before you can actually move it about - I'm assuming this is because it is rendering the webpart again in it's semi visible state.

I was wondering if it is possible to only have the title bar with the title of the webpart with any verb buttons rendered in the semi visible control that is attached to the cursor when moving a webpart. Is there a function in the webpart itself that I need to override? Or perhaps something to put into the RenderWebPart method of the chrome so that it wont call renderPartContents for the drag rendering?

Many thanks in advance!

After some further research I have come to conclusion that it is not possible - there is inbuilt javascript that simply clones the webpart into a floating div that appears when you go to drag a webpart. Maybe in future versions (I'm working in 2.0) this can change...

Initially I wanted to have the page in catalog mode all the time but to get a solution to the problem I have moved away from this. I have added a boolean property to my webparts that when set to false will not add any controls to the webpart. Therefore when my button is pressed to put the page in catalog mode, this flag is set to false meaning just the title of the webparts are displayed enabling quick cloning into the floating div.

Thanks to anyone that did try and find a solution.

special character in web link

thomasa11-Jun-09 3:17

11-Jun-09 3:17

How can I make the Response.Redirect() method or something inside that methode not
change the special character in the link.

here is my code:

<br />
string strURL = "http://www.myweb.com/doThatThing.aspx?run=th&amp;rp=Y"Ê"<br />
Response.Redirect(strURL, false);<br />

Unfortunately it somhow changes the special characters so it ends up lik

http://www.myweb.com/doThatThing.aspx?run=th&rp=Y%e2%80%9d%02%c3%8a%e2%82%ac

so the last part is changed from Y”Ê to Y%e2%80%9d%02%c3%8a%e2%82%ac

I'm not exacty shore where the text is change.

Any sugesstion?

Maby I can change the parameter back from Y%e2%80%9d%02%c3%8a%e2%82%ac to Y”Ê ?

Thanks
Thomas

CalendarExtender and translation is only doing half work

I have an odd CalendarExtender control.
I added EnableScriptGlobalization="true" EnableScriptLocalization="true" to the scriptmanager and now my control shows in Dutch except for the line 'Today: juni 11, 2009' On the ajax.asp.net example site the word 'Today' is translated into the Dutch verb 'Vandaag'.
How can the 'Today' also be translated into Dutch for my site? I am using control toolkitversion 3.0.30512.17815

Use 1 sitemap on different websites

I created a main project (called the Portal) that has the sitemap and master page in it. I created a virtual path provider so that other projects/site can use the master page. I created a project called WebTest that uses the virtual path provider to get the master page of Portal. But WebTest now complains that it can't find the sitemap.

I want WebTest to use the sitemap of Portal. How do I do this.

I've tried adding the following code in the web.config file:
add name="WebSiteMap" type="System.Web.XmlSiteMapProvider" siteMapFile="~/Tax.sitemap"

I do not want to use Sharepoint. Is there an easier why to share the sitemap accross IIS?

Gridview is Very slow on the Cells change event

Good Day all

i have a Ultrawebgrid i n my page and i display Data in this Way

STAFF                CYCLES
=========================
Galloway A Ms	  20,22,23,24,25,26
Gama, E	          20,22,24,25
Grieve S Ms	  20,25,26
Jones D Dr	  24,26

and a user can select the Staff in the Grid by Holding a Control key and i have trapped the selection in the Gridstaff_SelectedCellsChange and handled it like this

protected void Gridstaff_SelectedCellsChange(object sender, SelectedCellsEventArgs e)
{
    Change_Control_Availability_Cycles_Enable(); //Enable the Disabled button

    List<String> Array_To_Be_Replaced = new List<String>(); //This are the Values to be replaced, they will be stored in this array

    foreach (UltraGridCell cell in Gridstaff.DisplayLayout.SelectedCells)
    {
        if (cell.Column.Index == 0)
        {

            if (cell.Value != null && cell.Value.ToString() != "")
            {
                cell.Style.ForeColor = System.Drawing.Color.Red;

                Array_To_Be_Replaced.Add(cell.Value.ToString());

            }

        }

        else
        {

        }
    }
    Session["Array_To_Be_Replaced"] = Array_To_Be_Replaced;

}

Now when my user is selecting the Staff, this page becomes very Slow.

Can you please advice me on the approach and the Bottleneck in my code.

Thank you

the event is Gridstaff_SelectedCellsChange(object sender, SelectedCellsEventArgs e)

does the 'e' not have a reference to the cell that has been changed? Now you check the complete grid! Why check teh complete grid if you are only interested in the changed cell?

'Please advice with example code. ' --> what have YOU tried?

Text size problem while writing in an image

milpo11-Jun-09 1:59

Hi,

When a user uploads an image in my image mangement module writen in asp.net and csharp , i need to resize , write some text on top of it and save

This is working fine for all sizes of images but for large images i had to increase the font size used in code

The below code is working for small images(around 500x600)
g.DrawString("test", new System.Drawing.Font("verdana", 14, System.Drawing.FontStyle.Bold),System.Drawing.Brushes.Black, ((thumbNailImg.Width / 2)-5), (thumbNailImg.Height - 20));

But for large images

g.DrawString("test", new System.Drawing.Font("verdana", 35, System.Drawing.FontStyle.Bold),System.Drawing.Brushes.Black, ((thumbNailImg.Width / 2)-5), (thumbNailImg.Height - 20));

i need to change the font size to a larger value, otherwise it wont be readable in the image

Here is what i am doing

1) Resizing image uploaded to 250x200
2) Adding some text over re-sized image
3) Saving it

images sized around 500x600 text is readble but large images i need to change font size

I want to make font size fixed and write text on top of that with text in the image readable any idea how to do this

complete code listing is shown below

String UploadedFile = MyFile.PostedFile.FileName;
int ExtractPos = UploadedFile.LastIndexOf("\\") + 1;

//to retrieve only Filename from the complete path
String UploadedFileName = UploadedFile.Substring(ExtractPos,UploadedFile.Length - ExtractPos);

// Display information about posted file. Div is invisible by default
FileName.InnerHtml =UploadedFileName;
MyContentType.InnerHtml = MyFile.PostedFile.ContentType;
ContentLength.InnerHtml = MyFile.PostedFile.ContentLength.ToString();

FileDetails.Visible = true; //div is made visible
// Save uploaded file to server at the in the Pics folder
MyFile.PostedFile.SaveAs(Request.PhysicalApplicationPath + "images\\" + UploadedFileName );

//thumbnail creation starts

//Read in the image filename whose thumbnail has to be created
String imageUrl = UploadedFileName;

//Read in the width and height
int imageHeight = 200;
int imageWidth = 250;

//You may even specify a standard thumbnail size
//int imageWidth = 70;
//int imageHeight = 70;

if (imageUrl.IndexOf("/") >= 0 || imageUrl.IndexOf("\\") >= 0)
{
//We found a / or \
Response.End();
}

//the uploaded image will be stored in the Pics folder.
//to get resize the image, the original image has to be accessed from the
//Pics folder
imageUrl = "images/" + imageUrl;

System.Drawing.Image fullSizeImg = System.Drawing.Image.FromFile(Server.MapPath(imageUrl));

System.Drawing.Image.GetThumbnailImageAbort dummyCallBack = new System.Drawing.Image.GetThumbnailImageAbort(ThumbnailCallback);

double aspectRatio = Convert.ToDouble(imageWidth) / Convert.ToDouble(imageHeight);
//int maxWidth = 250;
//int maxHeight = 250;

//if (aspectRatio <= 1 && imageWidth > maxWidth)
//{
// imageWidth = maxWidth;
// imageHeight = Convert.ToInt32(Math.Round(imageWidth / aspectRatio));
//}
//else if (aspectRatio > 1 && imageHeight > maxHeight)
//{
// imageHeight = maxHeight;
// imageWidth = Convert.ToInt32(Math.Round(imageHeight * aspectRatio));
//}

System.Drawing.Image thumbNailImg = fullSizeImg.GetThumbnailImage(imageWidth, imageHeight, dummyCallBack, IntPtr.Zero);

//We need to create a unique filename for each generated image
DateTime MyDate = DateTime.Now;

String MyString = MyDate.ToString("ddMMyyhhmmss") + ".png";

System.Drawing.Graphics g = System.Drawing.Graphics.FromImage(thumbNailImg);

g.DrawString("test", new System.Drawing.Font("verdana", 14, System.Drawing.FontStyle.Bold),System.Drawing.Brushes.Black, ((thumbNailImg.Width / 2)-5), (thumbNailImg.Height - 20));

//Save the thumbnail in Png format. You may change it to a diff format with the ImageFormat property
thumbNailImg.Save(Request.PhysicalApplicationPath + "images\\" + MyString, ImageFormat.Png);

thumbNailImg.Dispose();
g.Dispose();
fullSizeImg.Dispose();

//Display the original & the newly generated thumbnail
Image1.AlternateText = "Original image";
Image1.ImageUrl = "~\\images\\" + UploadedFileName;

Image2.AlternateText = "Thumbnail";
Image2.ImageUrl = "~\\images\\" + MyString;

Thanks in advance

This is happening because of the postback that the button is creating. Just add "return false;" to your window.open() code. It will solve your problem.
