Forms Data Controls :: How To Reference Image Location Stored In DB From An Image Control
Apr 20, 2010
I'm not even sure if this is the correct approach for this -
I have a DB that stores information, as well as a location to where images are stored
ie ProductImage = ~/ProductImages/BulkRetail.JPG
I'm using a repeater to list all the products, which works fine for all the labels I use but not for the image location. I'm using something like this, but it doesn't work:
I have div In my page that in this div I put image control
<div id="DLogos"> <asp:Image ID="imglogo" runat="server" CssClass="ILogos" /> </div> according to below code <div id="Dart1_I1" visible='<%# !string.IsNullOrEmpty(Eval("image1").ToString())%>'>
If in database was image it show div and if there wasn't any image it didn't show div but above code is for div that I put in datalistnow I want do some thing like that for Div that I don't put it in datalist I should write code for that in behindecode page but I don't know How I can do it?behind code
SqlCommand _cmd = new SqlCommand("storeinfo1", _cn); _cmd.CommandType = CommandType.StoredProcedure; _cmd.Parameters.AddWithValue("@behcode", data); _cn.Open(); SqlDataReader _dr = _cmd.ExecuteReader(); while (_dr.Read())
I have one repeater that has one image(image1) bound from data base .also i have one pop up div that has another image(image2) without any image url.i wanna when click on image1 thats url put in image2's url and my pop up div show
How do you made a reference to an imagebutton in the code behind? I'm trying to show a high priority "!" image if an "h" was in the label. the code below.
I am trying to put a default image in an Image control in asp.net and it should show that particular image on the page when no other image is assigned or no image available in Database.
I know how to display an image in gridview from image path in database. Now, I want to display an image in an asp.net image control from image path in database. Can anyone point me to a tutorial? I haven't been able to find one that explains how to do it when I don't know what the image path will be. The images are in the root folder.
I'm amazed that it took me minutes to figure out how to retrieve text from a specific SQL database record and display it on my aspx page using FormView---and yet days later I still can't figure out how to retrieve/display the corresponding database image...(I feel like I went to a fast food restaurant, received my burger and drink in minutes---but for the fries I'm told to leave the restaurant, drive to another county, and search for the granite boulder under which I am to find the next clue in the quest to get my fries.
I don't want to waste anybody's time---I do see that this issue has come up here before (but each solution seems more complicated than the previous one): clearest way (or your favorite past thread on this topic) to retrieve/display/edit binary image data using FormView?
I'm new in storing and displaying image to database.I have learn how to store image into my database from a site and seems like it work, and the image is store as binary data.Now i try to retrieve and store it, using a site as a reference
My problem is i follow everything but in the end it seems the gridview do work as it shown some data from the database but for the image, only show a small red cross "unable to show image" sign there.
My storing data and uploading image to database code (Just in case)
This is probably a really simple question but I have a gridview that is linked to a table in a database. But I have an imagefile stored in one of the columns in the table. The SqlDataSource links to the table an I can see the images when I test the query. I just can't see how to show the image in the gridview. All the example on the web show how to link to an image on the server and not that is downloaded from the server.
I Used AsyncFileUpload(one of Ajac Control Toolkit Controls) to Uploading User's Image. this works well. But i want to change the image url of an image contorl to uploaded image url. how can i perform that? I put Image control in a Update Panel:
[Code]....
in C# code I wrote these:
[Code]....
But it does not work. Image is like Previous. Note that ImageOperations.ResizeFromStream() method resizes and saves the image to a specefic folder. actually I should trigger a Postback to Update the Update Panel but How to do that. I usedUpdatePanelNew.Update(); but it does not work!
I have been reading this forum post: http://forums.asp.net/t/1320074.aspx.I have found that I have to have the column which contains the image path showing in the gridview, in order to reference it using e.values("columnhere"). Is there a way I can do this without the column showing? I have tried setting the visible property to'false' but it still doesn't like it.
I have images saved in database, now I want to this images fetch from database and save into zipfile and return to the user for download in mvc4? How do that functionality.
Just wondering if anyone has ever managed to find a way to have a datagridview image button column in a template field which display different images on different rows depending on some data element in the row. Our application needs to display a series of fees charged against an account column which will be either less then 500, 500 to 1000 or >1000. Some of those fees are charged at a full rate, others at a partial rate, and some are not charged at all. The user would like to see a simple 3-state graphic which would convey the simple info: full-charge, partial-charge, or no-charge. Sounds easy enough but I've not yet managed to find a way to do this. Every time I attempt to modify the individual cell's graphic it seems to want to change the graphic for all the rows.
I am trying to change the image url of an image button in my gridview. I cannot seem to be able to do this in the code behind. Is there a way I can do this through the image buttons controls?
i have an image and an imagebutton, they are inside a listview and get their imageurl from databinding, i would like to know, if maybe the databinding value is empty, instead of showing a big red x, is there anyway to maybe make it link to a default image when the value is empty instead?
