I have a Gridview that I am trying to add Paging to, however when the 2nd page is selected all I get my EmptyDataText.
In reviewing multiple sites and forums they have stated to send your Datatable to a Session - What am I missing here?

View 9 RepliesIf there's a better way to accomplish what I'm attempting I haven't found it yet. That being said, I have create a gridview like the one here,[URL]And with some minor tweaking it working great for all my fields, checkboxes, etc. The issue is my last column is another gridview, and I'd like it to function the same. that is, a dynamic gridview inside of a dynamic gridview. I get that I have to create it initially with null values or it won't show up. I guess what I'm having trouble figuring out is instead of go will null data in the parent gridviews column, do I place my blank child gridview. Do I create and bind the child gridview first, or second. Generally just not sure. Also, as far as storing the data from the child gridview goes, will each one need it's own datatable?

Okay, here's something that I could easily do the hard way and manually wire up each form element and save it to a datatable in memory, but there has to be a more efficient way to do it.
Here's what I have:
1. A strongly typed datatable and tableadapter in a XSD name Orders
2. A formview control which currently is connected to an ODS connected to the Orders tableadapter, this makes it easy to wire up the databindings for each form field in design view
I would like to:
- bind the the formview to an instance of the strongly typed datatable, and then save the dt to a session object without interacting with the actual database
- load forms on subsequent pages from the dt in session
- ultimately save the dt info to an actual database table on the third page
I've read some solutions where a custom class is created, but to me this seems like almost as much work as wiring up the form field to the table columns manually in code.
I have a Webform with a TextBox (Static) and 3 TextBox (Dynamic - based on the following article: [URL].... )

I've got a GridView that's databound to a DataTable that I have stored in Session. I want to be able to add a LinkButton into this gridview so I can delete rows from the DataTable, however, I need to reference the rows in the datatable somehow.
I figured the simplest was

I have a dataset that has two datatables. In the first datatable I have EmpNo,EmpName and EmpAddress. In the second datatable I have Empno,EmpJoindate, EmpSalary. I want a result where I should show EmpName as the label and his/her details in the gridview. I populate a datalist with the first table, and have EmpNo as the datakeys. Then I populate the gridview inside the datatable which has EmpNo,EmpJoinDate and EmpAddress. My code is
[Code]....
My Design is
<asp:DataList ID="Datalist1" runat="server" DataKeyField="EmpNo">
<ItemTemplate>
<asp:GridView ID="Gridview1" runat="server">
</asp:GridView>
</ItemTemplate>
</asp:DataList>
I do not get results in the gridview, instead have errors. I tried then placing the bound field
<asp:GridView ID="Gridview1" AutoGenerateColumns="true" runat="server">
<Columns>
<asp:BoundField DataField="EmpNo" />
</Columns>
It throwed an error stating / A field or property with the name 'EmpNo' was not found on the selected data source.

I have a gridview generated from a datatable. One of the columns is "client name" whose data is generated from a class.
I added a link button for the column header that fires a sub that should sort the datagrid, but is not.
Here is the code I have so far that creates the gridview which works fine:
Private Sub PopulateCaseListGrid()
'Kill the existing DataSource, in case of a page reload
gvCaseList.DataSource = Nothing
'Create a datatable with whatever column you want to use

on which all conditions we use dataset and datatable to bind data to a gridview?
View 2 RepliesI need to pass the data from GridView1 to a DataTable, and then pass the DataTable to GridView2 and preview it. I have BoundFields and ImageFields in the GridViews. I think I am doing something wrong but I can't figure out how to do it. I know I have to iterate through the GridView.Rows, but I don't know how to pass it to the DataTable.
View 3 RepliesI have a Gridview and two link button in that GridView , one link button click is to add edit row ( Edit ), one link button click is to select row ( Select ). I have a dropdownlist inside row which selected when i click link button Select in the gridview edit template, as of my business logic i need to show the dropdownlist only when the user clicks Edit button and when the user clicks Select button . That mean when the user clicks Select button then they clicks Edit button on the gridvview i should allow him to edit the dropdownlist (showing the value to the user through a label).
ASPX CODE
[Code].... C#
When I click Select link button , then I click Edit link button . They have errors : Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index" I don't know what error?. How to fix it
If I am passed a datatable and I cant change the column structure..is there anyway to set an existing column to a Primary key so I can easily Find() the row I am looking for?
View 1 RepliesHow can I load (copy) the data that is present in the GridView into the DataTable? I am planning on loading the DataTable from GridView and update a row from the datatable and load the newly formed data with the GridView.
Note : Here I am not using datasource.
I have a gridView which is populated with the code below. This is working perfectly except for one issue. In the "Region" column, I need for each region name to be a hyperlink. If I set the row code to dr(0) = "<a href='table_display.aspx?IO_ID=" & objDataReader("IO_ID") & "'>" & objDataReader("Region") & "</a>" it actually displays the entire string of text from "<a href..." through "</a>", but not as a hyperlink. I have read in many places to manually put a hyperlink field in the aspx page, but I would really prefer to do this programmatically in the code-behind.

I am working with GridView/TelerikGrid control. It is having filter option. When I filter the data,
I need to copy only filtered rows into Datatable for further processing.
Suppose I am having total 10,000 records. and when I filter on column say Dept="IT", I get 1000 records in grid. So these 1000 records only should get copied into Datatable. So How to achieve this ?
Cwhat can be done over this ? I tried number of properties for grid. But there is no property which will return fileterd data source. Also I am not able to go every page of Datagrid and collect the data. I can get data for first page only. If I need to collect the data by going to every page of gridview, what is the way for this ?
Actually i want that HeaderText of gridview should be as column name of datatable, which i assign to that perticular column of gridview.
I have templatefield in that column and AutoGeneratedColumn is false
i want to show gridview footer when there is no records.
currently when i delete all record then footer not shown.
i tried

but not working
