I'm trying to create my own image viewer w/thumbnails using a datalist control. I found some ASP.Net code that utilizes another ".aspx" page to view the images. However, I wish to load the thumbnail images into a DataList control on my page and not another page. I've never done this before so I'm a little confused on the highlighted piece of code.

View 1 RepliesI created a datalist which contains hyperlinks that when clicked will redraw the page and update my another datalist in the same page. How do I hide this datalist after click any of its hyperlinks?
View 5 RepliesI am new to using ASP.NET and I am using a datalist to represent the data obtained from querying a database.However,I am facing 2 issues:
1) If the string returned after querying the database is too long,the datalist is displaying the long string as it is which is not looking good.I am using Eval to fetch the data from the database for the sake of displaying.I need to have some page breaks so that the information fetched is presentable.
2) While repeating the datalist I want to hide all the columns except for 1 column whose value are unique.Upon searching I found this link: http://www.programmingknowledge.com/DataList.aspx but the code is in VB and I am not familiar with it.I am familiar with C#.
I am inserting the front end code for my datalist.I also want to know if datalist is the best control to present the data from the database.
[Code]....
I have a datalist bound to a sql source having two columns: Name and Description. The datalist contains a "Show Description" link as follows on clicking on which it calls the javascript which shows the description div.
[Code]....
The asp.net page source for itemtemplate of the datalist is as follows.The problem is that since the div id "Description" is applicable to multiple records, no matter I click on whichever "show details" link, the description of first record in the datalist is shwon and hidden since its the first div encountred by the javascript. In other words, I want a way to show/hide the description of each record in datalist indivigdually.

how to hide a LinkButton inside a DataList? I've tried to do this but I do not work:
protected void Page_PreRender(object sender, EventArgs e)
{
foreach (var item in listanews)
{
DataList container = dlgestionenews;
if (string.IsNullOrEmpty(item.IdNews))
{
DataListItem itemdatalist = null;
foreach (DataListItem itemdl in container.Items)
{
foreach (Control control in itemdatalist.Controls)
{
if (control.GetType().FullName == "LinkButton")
{
((LinkButton)control).Visible = false;
}
}
}
}
}
}
I display images from database, suppose image is not upload means display the none image in datalist...
View 1 RepliesFor example in my datalist if Eval("OptionJ").Tostring = Null I would like the function GetVisible to set visibility of the radio button to false like so:
<input name="Q<%#Eval("ID")%>" type="radio" value="J" visible="<%# GetVisible(Eval("OptionJ").ToString()) %>">
<%#Server.HtmlEncode(Eval("OptionJ").ToString())%>
</option><br />
I then have a codebehind function like so:
Protected Function GetVisible(ByVal Evalresult As String) As String
If Evalresult = Nothing Then
Return "False"
Else
Return "True"
End If
End Function
I have also tried checking EvalResult = String.empty
In the outputted html the visible status is being set to false...
<input name="Q3" type="radio" value="J" visible="False">
But it is still displayed on the page!
How to show defalut image in datalist untill large image fully loaded in same datalist ?
View 1 RepliesI have a gridview inside a datalist, i need to hide a particular column of that gridview inside datalist. how should i proceed????
View 1 RepliesBasically I have a dropdownlist (ddlSystem) and an AJAX update panel. Inside the update panel I have an asp:GridView (gvSystemSpecs) and an asp:Image (imgLoad).
For triggers on the update panel I have:
[Code]....
When the user changes ddlSystem it makes a service call to pull back a bunch of data and populate the gridview.
I want to be able to show a loading image (imgLoad) when ddlSystem is changed. Once the function to pull data and populate the gridview is complete I need to hide the loading image.
I think I'll need to use some JavaScript, but what ever I try doesn't work and I don't know if the update panel has anything to do with it...
