Forms Data Controls :: Listview Show Image On True?
Apr 27, 2010
I have this ListView with several columns, one of the columns is called On Sale. The value of this is either true og false (or null). What I want is to show a little image if the cell value is true, otherwise don't show any picture.Below is some code I have used to pull out some picture names (e.g. CarThumb.jpg) from the database.
[Code]....
However this time the value is not a string, but true/false. And according to this I need to pull out the samme picture (OnSale.gif where to do the checking for the true or false values and according to this value show the OnSale.gif.
I am attaching an image to a listview from code behind, the image depends on a value from the database and there are 5 different images.It sometimes works fine and then will randomly come up with an error, when nothing has changed, the error is:[Code]....
It doesn't seem to make sense to me because ImageUrl IS a member of image. Here is my code:
It took me a little while to figure this out, but the AllowPaging="true" on the FormView seems to be the culprit. I don't have much experience paging from a FormView, but for this requirement the customers wants this kind of UI.I have a FormView with DefaultMode="Edit", which is bound to an EntityDataSource. One of the entity's properties, "ExternalID", determines whether some of the other properties in the entity are read-only. For example, if IsExternal==null, the FirstName, LastName, and Email fields should be rendered as TextBoxes. If IsExternal!=null, the 3 properties should be rendered in Label controls.
How would I go about showing the insert row in a ListView? Intially, when I went to configure the ListView, the Enable Update, Delete and Insert checkboxes were all greyed out. I changed a bit of the template code and couldn't access this screen anymore but that's not really a big issue.The Edit and Insert templates are present in my source. To get editing working, I simply adding an asp:Button to each row with the CommandName 'Edit'. However I'm a bit confused as to how I can get the insert row to show. Do I have to create a new button there with the 'Insert' CommandName? If so, where should I put it? Is there another way of doing this?

I have a listview. Inside the EditItemTemplate of this listiview I want to show a Checkboxlist that has 5 checkboxes; S, M, L, XL, XXL.

The columns are S, M, L, XL, XXL (same name as checkboxes for convenience) and all have datatypes bit. What I want now is to be able to databind this query result to this CheckBox list.

I have a data list view on a site.. Everything so far is done with minimal coding so I hope to find a similar solution for this as well :) (if such exists, of course)
When I display images from database, i have a default image that is to be displayed if there is no image in the database...

how to display DEFAULT img when there is no link in the database?
It should be simple, but I didn't found yet how to do it. There is only one user (Admin with user name and passowrd, he has a cookie so I know when he is watching the page) I would like to show him the Update/Delete/Insert button options in my ListView, but to the other users I don't want them to be able doing this kind of things, So it should be hidden from them. How I am doing it in C# code? Showing/Hiding these buttons?
I have to flip or rotate images in listview itemtemplateI will catch the image id by commandargument and get imageid, and rotate it and save it back in original placei tested roate image coding , it worked perfectly. but when i combine with listview and doesnt work.
i have a website which has a listview control and databind in a SQLdataSource Control, and in its ItemTemplate has a HTML Image Control.
but when i run the website, it displays other fields from the Database but the image is not displaying,
to test if there is a problem in the link of the image or the image it self,
i add a Repeater control just under the ListView Control and Copy the whole ItemTemplate from ListView to Repeater and when i run the website, the image in the Repeater is displayed but the ListView does not.
I get pic and data from database using data list , and want to know to show up image in box with any larger size when mouse over the pic this pic show image i want and code
On my main page I have a repeater that pulls the last 3 entries from the database. I want to be able to add pictures to the database and show those in the repeater, but only if the column is set to true. I can't seem to get past the part about have the image show only if its supposed to.
Here is the code for my page:
[Code]....
Code Behind:
[Code]....
SP:
[Code]....
So my questions are: Is the repeater the correct control to use?
How do I only show the image control if the column "NewsImgShow" is true?
