I have a table with the following structure,
I need to restructure the table to show the CustomSpaceName in the following order,
Space3 Personal Case Quick case
Space1 Space2
For each entry I will create a link button and pass the CustomSpaceId in query string.
So which is the ASP.NET Data Control matches best with my requirement. I think using the loop and generate table structure is a BAD idea.
No Need of doing that with a old method when ASP.net gives you GridView and other Data Bounding controls
Basically gridview will do the same operation that you told in a efficient way.
You can use the in-built methods.
Grid View
Repeater
ListView
DataList
Here I will recommend DataList.
Use RepeatColumns="4" property.
<asp:DataList ID="DataList1" RepeatColumns="4" runat="server">
<HeaderTemplate>
<asp:Label runat="server" ID="lbl1" Text='Header'></asp:Label>
</HeaderTemplate>
<ItemTemplate>
<asp:Label runat="server" ID="lbl1" Text='<% Eval("CustomSpaceName ") %>'></asp:Label>
</ItemTemplate>
</asp:DataList>

Hi I was wondering if there is any way to bind my server side panel which contains multiple textboxes ,so my textboxes show associated bound fields which coming from data base automatically .
something like this:
in code behind:
myPnl.DataSource=myContext.TableName;
in aspx page:
<asp:Panel runat="server" ID="myPnl">
<asp:TextBox runat="server" Text='<%# Bind("Title") %>' ID="txtTitle" ReadOnly="true">
i have used grid view to display data. Now i need to edit the row. I have kept edit link button in template field of grid-view. Now when i click the edit button, i need to retrieve the data for particular row into the server controls, so that user can enter the data into it.
How can i do that?
let me know if any info required..
thanks!

Now, when i click edit from below grid, the data in grid should come up in above form.
There is a different template available in Gridview and you have to use it properly. For example, if you want to edit something, the editTemplate is available for that.. look at the following sample:
<asp:GridView runat="server" ID="grd">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:Label runat="server" ID="lbl"></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox runat="server" ID="Textbox1"></asp:TextBox>
<asp:HiddenField runat="server" ID="hdf" />
</EditItemTemplate>
<InsertItemTemplate>
<asp:TextBox runat="server" ID="Textbox1"></asp:TextBox>
<asp:HiddenField runat="server" ID="hdf" />
</InsertItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
have a look on these article

This is such a general question that you should really review how the GridView works in the first place.
Try reviewing the following example from MSDN regarding GridView editting;

I have a listview nested inside a gridview.
I'm trying to get paging working on the listview. I thought that it would display the paging controls, and just page through them normally.
It does display the controls, and limits the result set shown to the appropriate number of records (pageSize) but when I click on the paging controls the grid refreshes and nothing changes with the nested listview (it's still on the first page).
I've tried nesting the listview inside an updatepanel, but the behavior remains. The gridview itself is already in an updatepanel.
So this is the layout I've got:
<Gridview ID="gvApplications" DataSourceID="odsApplications" DataKeyNames="ID" AutoGenerateColumns="false">
<Columns>
<asp:TemplateField HeaderText="Functions">
<ItemTemplate>
<asp:ListView ID="lvFunctions" runat="server" DataSource='<%#Eval("ApplicationFunctions") %>'
DataKeyNames="ID">
<LayoutTemplate>
<asp:DataPager ID="dpFunctions" runat="server" PageSize="1" PagedControlID="lvFunctions">
<Fields>
<asp:NextPreviousPagerField />
</Fields>
</asp:DataPager>
<ul>
<li>
<span ID="itemPlaceholder" runat="server" />
</li>
</ul>
</LayoutTemplate>
<ItemTemplate>
<asp:Label ID="lblFunction" runat="server" Text='<%# Eval("ApplicationFunction.Name") %>' />
</ItemTemplate>
</asp:ListView>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</Gridview>
Ideas?
Honestly, I would consider using a master-details pattern here. There are a lot of code examples on this. For example:
Google: Master Details Examples with Child Objects
There are also scenarios where the details view (child objects in your case) would display on a separate page. Either way, by displaying the child objects in a separate details view, you avoid the coding and display issues that come with nesting.
Matt Berseth has some of the best code examples out there on this topic:
http://mattberseth.com/blog/gridview/
Listview / datapager combination do not work properly if the listview does not use a datasource control.
Try including a datasource control (objectdatasource could be applicable) in the template field.
I'm building a GridView on the fly, and I'd like to pre-define the TemplateFields to be included ondemand. So, what I'd like to do is have a declarative file that defines how the different templates look for a specific column. Like:
<asp:TemplateField>
<HeaderTemplate>
this is a text column
</HeaderTemplate>
<ItemTemplate>
data goes here
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox Text="databindhere" />
</EditItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<HeaderTemplate>
this is a bool column
</HeaderTemplate>
<ItemTemplate>
if(true) "yes" else "no"
</ItemTemplate>
<EditItemTemplate>
<asp:CheckBox Checked="databindme" />
</EditItemTemplate>
</asp:TemplateField>
So, if my query had a text and two bool fields, I could push the appropriate TemplateFields in the the Columns property as needed. (I hope I'm making sense here)
So, how would I go about creating declarative files for the above definitions? And then, how would I reference those definitions programmatically?
Ok, what would work best is to subclass System.Web.UI.WebControls.TemplateField, but when I do that, I can't seem to use the object with the <%# Register %> directive. If I could, I'd create a handful of UserControls with the new derivative, and then LoadControl() and Add() them to the Columns of my grid as needed.
Any ideas?
We've got a number of gridviews that we're populating with data from an ADABAS datasource via some middleware that, unfortunately, gives us back lots of arrays of stringBuilder that we turn into a datatable, set as the datasource for a gridview, then bind.
It's convoluted, but I'm in a situation where I need to be able to update the gridview (say, drop a row), without going back to the mainframe, deleting the row, and regenerating the datatable, as I would if we had an Oracle datasource.
So, I'm trying to hack something together where on serverside I extract the data from the gridview, build a datatable, delete the given row, then use that datatable as the datasource for the gridview, and rebind.
I can do it on a case by case basis, so long as I know the layout of the gridview. But we're going to be doing this over and over on this current project, I'm trying to figure out a way to abstract it so that I can use it for any gridview I throw at it.
The problem I'm getting is that most of the cols in the gridview are templatefields with asp:labels, where the data is put in with the databinder.eval thing:
<asp:TemplateField HeaderText="Code">
<ItemTemplate>
<asp:Label ID="lblCode" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "code")%>'></asp:Label></ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Title" ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Center">
<ItemTemplate>
<asp:Label ID="lblTitle" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "title")%>'></asp:Label></ItemTemplate>
</asp:TemplateField>
So, when building my 'fake' datasource, I need to be able to extract from somewhere in the gridview those column names.
Is that information available in the gridview?
Yikes. You are going to need to store the fake datasource column names within the GridView along with the column values. One suggestion would be to add a HiddenField along with each fake datasource field value. In the example below, display the code (value) in the Label and the column (name) in which code maps in the HiddenField:
<asp:TemplateField HeaderText="Code"
<ItemTemplate>
<asp:Label ID="lblCode" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "code")%>'></asp:Label>
<asp:HiddenField ID="hfCode" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "codefield")%>'></asp:HiddenField>
</ItemTemplate>
</asp:TemplateField>
It's ugly, but the column names will always be available to you -- no matter what they might be. Best of luck.
