Forms Data Controls :: Picture Failing To Load On Form?
Sep 23, 2010
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()
I have a website which uses the latest AJAX Control toolkit. On my pc, the website is loading perfectly well. The page makes use of a tab control and an update Panel - AJAX Control toolkit.Unfortunately when I uploaded the website online, on the shared web server, the website gives the following 3 errors (on IE) :
1) ASP.NET Ajax client-side framework failed to load 2) 'Sys' is unidentified 3) 'Sys' is unidentified
The page finally loads, however the ASP.NET Ajax controls do not load (Tab controls and UpdatePanel). The rest of the page loads perfectly well. I made some searches online, however still cant find a solution.
Facts:1. The site contains an Ajax Script Manager Proxy2. The web.config states that the site is not in debugging mode3. Tried to create a fresh new virtual directory and problem still persists. 4. On my Development machine the website is 100% functional.
I am trying to pass a mysql reader string variable into a textbox so on the asp front end it will automatically show the resultset as soon as the page is loaded. The following is my code:
protected void Page_Load(object sender, EventArgs e) { if (!Page.isPostback)
Currently i'm saving pictures to our sql server db. A user can go to a clients info page and click an id card image to open a new tab or window and see the picture saved for that client.
What I would like to do is when a client info page opens a small version (thumnail) of the picture to display and let the user click the thumbnail to open a bigger icture in a popup window.
I have been using the RemotePost Class( as per http://www.jigar.net/articles/viewhtmlcontent78.aspx) to post a form to a pay provider, for about 3 months successfully, I made some changes external from the call to this class that sent an email when user presses the button to notify us that the user has selected to go through to the pay provider (similar to PayPal). and suddenly got an exception error MSCROLIB, Thread was being aborted. I have since removed the code and I still get the error it happens when I call
[Code]....
I tried the suggestion on KB article [URL]/ but the control is not past to the Pay Provider I also took the actual response that is written and posted it to a new html file added a submit button and it works. So I am no stuck. The Pay provider claims they have changed nothing, and has tried to help but says they are receiving no input from either our dev site or the live site.I also tried to step into the call but it just throughs the exception
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??
I 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:
I 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:
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 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.
I 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,
I have a webForm which host a gridview and a formview. The formview is used for showing/editing a record which the user Select from the gridview.
In the formview Edit template I used DropDownList controls with
SelectedValue='<% bind("datafield")%>'
for enabling the user easier interface. A few of the DropDownList controls need to have a list of 100 items and I want to load the items from code behind and not from the aspx.
I tried to update the DDL's from FormView.Load, FormView.ModeChanging, FormView.PreRender but nothing I am getting an error like this:
[code]....
How do I load the DropDownList controls with items BEFORE the form databinding occurs.
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:
Page (Picture.aspx) using a repeater displays the image ---> http://postimage.org/image/iyl7rv1g/After click on link Delete opens a new page (DeletePicture.aspx) andimages in the database set to passive stateand this page(DeletePicture) closes.How to make the images on page (Picture.aspx) refresh and passive image is not visible.
when i click the picture that is displayed in the detailsView ImageField, the jquery lightbox pops up, but does not show the picture. it shows a red x in the middle of the lightbox. the same thing happens with the asp:Image control shown in the code below. The picture is stored in a SQL database Image datatype. Using master pages.
I ve an application dat am working on. The section of the upload picture works perfectly on the development environment and also on a test server but the issue comes up when it was hosted life. I started geting an error dat says picture could not be attached. I ve a folder cald Passport and dis ve been working for me on befor now but i dont now the reason y its not working now.
