how to hide a column of gridview when I add data in rutnime?
GridView.Columns.Count will be 0 when you set AutoGenerateColumns="true" in your GridView. You could try explicitly declaring your columns and setting AutoGenerateColumns="false", or you could try using this in your codebehind: GridView.Rows[0].Cells.Count to get the column count once the data has been bound, or this: protected void GridView_RowDataBound(object sender, GridViewRowEventArgs e) { e.Row.Cells[index].Visible = false; } to set a column invisible using the GridView's RowDataBound event. Edit 1 You can use bound field as follow <asp:DataGrid ID="DefaultGrid" Runat="server" AutoGenerateColumns=False> <Columns> <asp:BoundColumn DataField="Index" HeaderText="Header"> </asp:BoundColumn> </Columns> </asp:D

Hide Duplicate Rows in Core Data Driven UITableView
I think the best approach is to create an array containing all the data you actually want to display. You can assign your first source to the array and for the other ones you first verify that the item doesn't exist before adding it. If you know how the duplicates can be presented then you can write the necessary conditions that need to be passed before adding it to the array.

Gridview returning empty even when there is data. I want to use data in the gridview to update another database
Per my comment above you may want to do something like: List<string> _OrderIds = new List<string>(); DataTable table = gvOrderLines.DataSource as DataTable; foreach (GridViewRow gvr in table.Rows) { Label myOrderIDLablel = (Label)gvr.FindControl("lblOrderID"); //find control since it is a template field _OrderIds.Add(myOrderIDLablel.Text); } I hope this get you headed in the right direction.

display gridview data in another page or other gridview with row data in editable mode
You need to add RowCommand Event in GridView. <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" OnRowCommand="GridView1_RowCommand"> <asp:LinkButton ID ="lnkEdit" runat ="server" CommandArgument='<%#Eval("Recordid")%>' CommandName ="cmdEdit" Text ='Edit'></asp:LinkButton> </asp:GridView> Here rocordid is the id of your record. In Page behind you need to write code. protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e) { if (e.CommandName == "cmdEdit") { string Recordid = Convert.ToString(e.CommandArgument.ToString()); Response.Redirect("EditPage.aspx?recordid="+Recordid ); } } On EditPage you can get recordid from the query string and can fetch the record form the datab

How to eliminate duplicate rows from Gridview
My database does not contain duplicate rows. But your query probably is returning duplicate rows. Try debugging your query in Query Analyzer / SQL Management Studio - the CROSS JOINs look suspicious.

GridView - Hide Column but Use Value
Assign the ID to the DataKeyNames collection will work fine, is that an issue for you? The data keys is available for each row, not showing up in the UI, but still accessible with the row data, so you can get the ID for each row. You just have to get it from the DataKeys collection, instead of the row directly. You can add code to hide the first column (the ID) so that it doesn't appear, and rely on using the datakeynames to get the ID value... if that doesn't work, could you elaborate on why so I can adjust my answer..

Conditionally Hide Checkbox in row of Gridview
LinkButton.CommandArgument is implemented in this way(ILSpy on .NET 4): public string CommandArgument { get { string text = (string)this.ViewState["CommandArgument"]; if (text != null) { return text; } return string.Empty; } set { this.ViewState["CommandArgument"] = value; } } So as often in ASP.NET the property is never null but String.Empty.

Core data posting data to web service preventing duplicate posts?
I would suggest having 3 flags for uploads in your core data object. 0 => upload failed, 1 => currently uploading, 2 => upload complete. As soon as the user selects to upload the post set the flag to currently uploading, in which case you set the update button to a spinner or something. When it completes, either failed or finished then change the upload button to done or re-upload depending on the flag. This seems like the obvious answer hope I understood your question correctly.

Core data: How will you avoid duplicate while inserting data in coredata
If you can use it, RestKit will do it for you. But it basically does the same thing. It offers some caching options to make the duplication check quick but there still has to be a check somewhere. I'm not sure how you think the FRC could help with the duplication check. Using a fetch request to get a dictionary result containing only the appropriate identification attributes maybe, but not a full FRC. Core Data itself has no concept of a 'duplicate'. See the Apple documentation section 'Implementing Find-or-Create Efficiently' here for recommendations.

Read Efficiently Paging Through Large Amounts of Data for a walkthrough of setting up custom paging with a GridView control. You will need to have a separate query for the total record count, which should be done first. Then you can calculate the number of pages the grid will have in order to build the paging controls. Total record count / records per page = number of pages Note: the records per page may be hard-coded in the GridView markup or you can have a control on your page that allows the user to pick a page size.

Data Binding in GridView
You'll need to bind a list, like a List<FavData> or an ObservableCollection<FavData> to the Hub. Right now, you've got a GridView that among many other attributes, includes initialization of the ItemsSource property. This property is used as the source for a list of items. <GridView x:Name="itemGridView" ItemsSource="{Binding Items}" </GridView> The binding is specified as {Binding Items} which means that for whatever object is bound currently to the Hub, grab the List stored on the Items property. As you currently had set a single FavData instance to the Hub via the DataContext property, and it did not have a property called Items, there was nothing to display. So, my suggestion is to create a list of FavData instances and bind that to the Hub instance instea

Get data from the row of a Dropdown in a Gridview
Check the GridView's DataSource before you do the DataBind(). Since you're missing the full ASPX markup, I'm not sure if you're setting the data source programmatically or with a SqlDataSource. In any case, what will happen often with programmatically-set Data Sources is that they disappear on a PostBack, and when you call that DataBind, you're really DataBinding it to null, which would explain why you're getting string.Empty ("") for the Label's Text property.

From your comment, you seem to mean only data where the first two columns are duplicated. The easiest way, I think, is to use row_number(), which is available in most databases: select name, country, status from (select t.*, row_number() over (partition by name, country order by (case when status = 'Pending' then 0 else 1 end) ) as seqnum from t ) t where seqnum = 1

Keeping Data in GridView after PostBack
This is by design. The problem here is that the SqlDataSource gets re-created when the page loads it does NOT maintains the selectcommand on postback but rather reverts to the one that was set when the DataSource was created. So you need to tell the the SqlDataSource what it had for SelectCommand when it last loaded correctly. Just store the SQL COMMAND in ViewState and enable encryption to protect the contents by setting ViewStateEncryptionMode on the Page directive. [ Always choose security as a standard ] <%@ Page ViewStateEncyptionMode="Always" %> In your button click event store your new command in view state: ViewState["currentCommand"] = "SELECT * FROM USERS WHERE user_id = 1"; UsersSource.SelectCommand = ViewState["currentCommand"]; GridView1.DataBind(); Now in you
