I add a table or div inside to datalist itemtemplateı want to change dynamicly table or div id's value from codebehind databound event. ex : I want to add itemindex value to table or div id which is inside itemtemplate
View 7 RepliesHow can I access the datalist at run time to create, a table layout but with the first cell having a rowspan of 2? Below is the HTML source code to demonstrate.
<table border="1">
<tr>
<td rowspan="2">1</td>
<td>2</td>
<td>3</td>
</tr>
<tr>
<td>5</td>
<td>6</td>
</tr>
</tr>
</table>
The following seems reasonable, but it returns an error:
<asp:Repeater ID="RepeaterF" runat="server" DataSourceID="DSF" >
<ItemTemplate>
<%
If Eval("Item_Batch") = 0 Then
%><tr><td></td><td colspan="2"></td><td></td></tr><%
Else %>........
Error: "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."
I am finding it difficult to accept that the whole Repeater approach has any benefits over just creating a loop in code, iterating through a recordset, and building a html table into a variable, then dumping it to the page. This repeater is spawning pages of code and objects, and surely this is all using up server resources.
This is my ASP.NET Page :

View 3 RepliesI must create a few DataLists programmatically. All of them will share the same ItemTemplate. Is it possible to define this ItemTemplate in .aspx file, using wizard etc, and then create DataList programmatically and assign this template? There is information in the internet how to define both ItemTemplate and DataList programmatically, but I want to define the ItemTemplate statically and only DataList programmatically and then assign the template to it.
The problem that I encounter is that ItemTemplate tag only works inside some control tag. It looks like it is impossible to define an ItemTemplate (like e.g. resource in Silverlight) not associated with any DataList, using the wizard and design tools, and then reference this template in code during runtime.

Very new to ASP.NET (using C# behind) and am having trouble figuring out the following scenario. I have a DataList that is populated (code below) and wanted each cell to be clickable. When the cell is clicked I wanted to know the unique ID for that cell. In my code behind, my OnClick method looks like this:

However I never get there. It seems as if the linkbutton always refers to some javascript callback function and just reloads my form. Am I using the wrong control for what I want to do? From this click I want to look up more information from the Key (will roll up the datalist or set visible to false, then supply the new data on the same page)DataList:

I want to add controls (or simply texts) to a ListView inside the ItemTemplate at run time.
The reason is that in my application I don't know in advance how many controls (or texts) I should insert.
For example I have to read the fields from a database table and insert in the ItemTemplate controls according to those fields:
<ItemTemplate>
<%# Eval("fieldname1")%> - <%# Eval("fieldname2")%> - <%# Eval("fieldname3")%> - .....
Afterwards I have to bind the ListView to the table content, so I need to preserve the <%# ... %> structure for the binding

I have a simple user control which is nothing but a simple input field with runat="server":
<input id="mySimpleTextBox" type="text" runat="server"/>
My observation so far in the output rendered by a datalist (when I use this user control inside it) is that the value for the name attribute is the same.I want to use this control inside a datalist/repeater such that I'd want a unique value for the input element's name attribute when the datalist/repeater renders. How is this done?
EDIT: My bad obversation. Actually the names are unique. However, when I try to post the page to another web page which outputs the key & value of all the items in Request.Form I don't see the input elements...
Now I have a datalist

Here's a short explanation of my asp.net project.
1) the default page loads, it will read the Windows Login of the user opening the page.
2) I'll check if this login exists in a table stored on the webserver.
In this Access Database, there's a 2nd linked table, pointing to another access table on a network location. Now, I want to read data from this linked table. However, at this moment I receive an error:
"The Microsoft Jet database engine cannot open the file '\<ip><shared-folder>statistics.mdb'. It is already opened exclusively by another user, or you need permission to view its data".
Some extra info:
- The network folder has read and write permissions for everyone
- the user and group permissions on both access files are set to read/modify/administer for the Admin user (on the tables I want to read from)
- IIS authentication on the server is set to "Windows Authentication" (this is needed so I can read the Windows Login from the user). All other authentication modes are disables (like anonymous, ...)
- When the error occurs, no other program or process has access to the statistics.mdb (so, it can't be locked by someone else)
- the web.config files access connection string looks like:
<add name="AccessConnectionString" connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\<IP><shared-folder>statistics.mdb;User Id=admin; Password=;" />
Like I said before, in this statistics.mdb file, there are 2 tables. One normal table, and another linked table (pointing to a network location)
Searching for solutions, I discovered the following:
- if I don't use linked tables, everything works fine (however, I have to use this linked table)
- even if I connect directly to the table in the network I receive the error. So, I'm pretty sure I don't have sufficient rights to read from this table.
I read that not the Admin user is opening the file, but actually a user called ASP.NET. This user doesn't have the correct rights to do this. However, I'm not sure if this is true.
