How can I check the resolution of a remote picture (jpg, gif) using the URL of the picture rather than a locally stored picture?
I attempted this, but get an error.
[Code]....
In my webform I have a datalist that displays images that are approximately 200px each. The datalist is set to RepeatColumns = 5, RepeatDirection = Horizontal (display 5 images per row). With the padding and spacing, each datalist row takes up about 1200px in width.
The problem is that if a user with a 1024x768 or 800x600 resolution visits the page, he'll see the horizontal scrollbars. It's not really a problem, but, well...
Is there any way I can call a javascript function in page_load that will get the screen dimensions, and send that javascript result to my serverside so that I can change Datalist.RepeatColumns?
My javascript function would probably use screen.width and screen.height, but how do I send those values to my codebehind?
i'm new to c# and i wanted to know how can i allow user to upload a picture from a text box and a button??
after uploading the picture, how can i save the picture in the database??
**note**the picture i allow user to upload need to be in a fixed size.
I have this code to insert a picture from database into an ImageControl on my ASP.NET form:
strConnString = "server=" + Server + ";database=" + DataBase + ";UID=" + UID + ";password=" + PASS + ";";SqlConnection MyConnection = new SqlConnection(strConnString);SqlCommand MyCommand = new SqlCommand("SELECT Pic FROM MEN WHERE ID=5", MyConnection);MyConnection.Open();SqlDataReader MyReader = MyCommand.ExecuteReader();if (MyReader.Read()){ byte[] m_MyImage = (byte[])MyReader["Pic"]; Response.BinaryWrite(m_MyImage);}
And I have this ImageControl on the form:
<asp:Image Width="88" Height="100" Runat="server" ID="m_Image" NAME="m_Image" />
but when I run the code, I see the picture big on the screen and not in my ImageControl.
i also put this in the form_load:
m_Image.ImageUrl = "MyPhoneBook.aspx?m_Image";my control is: m_Imagemy control ID is: m_Imagemy namespace is MyPhoneBook
but still dont work
How to insert picture into DB from formview?
What control I have to use to locate picture and what technique to adopt.
My working enviornment is 2.0.
In database the table is already created with Binaryfield to store pictures.
i have a gridview with a upload control in edit template. and a image control in item template bound to page that gets the new uploaded picture.the trouble is it does not return a picture no matter what i try??
View 2 RepliesI had a problem before with GridView displaying picture and it was solve as post [URL] shows. I am trying to apply the same coding to another GridView with a different configuration and I am having a hard time making the adaptation. May someone take a look at it. What I am trying to add to this GridView is code as:
DataImageUrlFormatStringl='<%# IIF(System.IO.File.Exists(Server.MapPath(string.Format("~/UploadedImagesClassifieds/{0}{1}", Eval("AutoNumber"), "Pic1.jpg"))), string.Format("~/UploadedImagesClassifieds/{0}{1}", Eval("AutoNumber"), "Pic1.jpg"), "~/UploadedImagesClassifieds/NoPicture.gif")

I have a grid view with some date [URL] I have column 'Zdjecie' with picture url and last column with camera button.
I wish that after clicking on camera button from last column, picture of url from column 'Zdjecie' wil be displayed.
I have atached event like this to clicking on camera button:
protected void grvWojewodztwa_CustomButtonCallback(object sender, DevExpress.Web.ASPxGridView.ASPxGridViewCustomButtonCallbackEventArgs e)
{
if (e.ButtonID != "ShowPicture")
return;
string vrlUrl = grvWojewodztwa.GetRowValues(e.VisibleIndex, "ob_zdjecie_link");
}
and i debugged it and vrlUrl is really picture url, but how to show this picture in new window or popup?

Dim row As GridViewRow = GridView1.Rows(i) [code]....
i have a UP and DOWN buttons ouside a gridview and a checkbox inside the templated field .I will check the checkbox to sleect a row , after that if i click on UP button the checkbox above the selected checkbox should be selected.
same with when i click on DOWN button the checkbox below the selected checkbox should be selected.

I have a grid view with two columns...one column has a no. like (123) and a check box....which user can checked or unchecked......all I need to do is that I need to disable the man handling of that check box......rather I would like to see a seperate grid view with the same no. of rows as of the first and in this gridview I may allow to type in or scan the no. and if this scanned or typed number matches any no. in the first gridview number then the corresponding check box should be checked/unchecked.
View 1 RepliesI do a gridview code that when displaying the information that come from the database is not showing any error at all, but is not displaying the right picture. The problem, I think, is that the (Eval("....") is not reading the values that are coming from the DataKeysNames. Due to this the right pictures are not displayed. But in another column, just for testing purposes I was able to display the values from DataKeysNames with the Eval. So I do not know what is going on and to make worse browser is not giving me any error. So, this is the line that is not processing, reading or executing well:
ImageUrl='<%# IIF( (Eval("TUDTIWasItemUpgraded")) = "Yes", string.Format("~/Images/ItemUpgradedTo.gif"), string.Format("~/Images/ItemNoUpgradedYet.gif") ) %>'

Dear all; I have a gridview as follows below
ID ZONE
A AFRICA
B NORTH AMERICA
now, i would like to add a little picture icon on the leftmost side of the gridview, that would allow a user to click on it...which will indirectly bring up a pop-up screen. In the pop-screen, i would like to add a textbox and a button to it, in which the user will be able to use to make an update to a field ID in the gridview.
I have an .aspx page with a gridview and a details view for looking up products. It is working perfectly. When I select "Details" on the gridview the details view accurately populates.I added an image named TagImageand need that image to display the correct one based upon the product changed when "Details" is hit. I'm using code behind and have checked my image directory string to make sure it is OK but the images do not display. Here is the vb.net code hehind I am using that successfully populates the details and was hoing it to display the picture:
Protected Sub GridView1_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs)
AccessDataSource2.SelectParameters("ProdID").DefaultValue = _
GridView1.SelectedDataKey.Value.ToString()
[code]....
i am using grid view when i define one of my culomns in sql data base as image then i can't put jpg image in that culomn so i can show this in grid view eather.
View 1 RepliesI am using VWD 2005 Express and Visual Basic.When my SQLDataSource feed my GridView, it does get the AutoNumber (GUID) of each record as well, to use it as a name for stored pictures. Pictures are not in the database but in a folder. Since I have several pictures, I do manipulate this ID with code and I add to it, pic1, pic2, etc and that is the final name for each picture, for each particular record. Example: The ID for one record in the database may be, 45623sdgd. If I have four pictures for this particular database record, the names will be, 45623sdgdPic1, 45623sdgdPic2, 45623sdgdPic3, and so on after Pic is added. After this I save these pictures in a folder.
Now, when I display the record information with a GridView, I get the AutoNumber of each record using: DataKeyNames="AutoNumber". I want to display a thumbnail picture link as well. But I really do not have many options in term of what control to use for the thumbnail inside the GridView. I tried the following controls unsuscesfully. HyperLinkField, can not add a picture to this one. ImageField, can not add a link to this one. ButtonField does not have a DataImageUrlField="AutoNumber" to get the AutoNumber. So since to be that my only opton is the asp:TemplateField. But it is giving me error with the coding. This is my coding,
Code:
<asp:GridView
ID="PublicClassifiedsSamplesGridView"
runat="server"[code].....
I do have the following code for for a GridViewd that display pictures that are stored in a file. I am using AutoNumber(GUID) from the database to name the pictures before I stored them to the file. I can save up to 4 pictures using the same AutoNumber but adding these ending to it, Pic1, Pic2, Pic3 ,,,,etc.
The problem that I am having is that after I get the AutoNumber from the database, I want to display a standard picture on the GridView field if there is not particular picture associiated to this record in file. The name of the standard picture is located in the same file under the name of NoPicture.gif. How can I do this? So far this is my GridView code and it is working fine:
