Hi, I am trying to put a data in a label but it gives me this error 'Object reference not set to an instance of an object', here is what I am trying to do: Label1.Text= GridView1.SelectedRow.Cells[0].FindControl("Status").ToString();
Any help how should I solve this bug? Thx

Your debugger should be helping you. Any of the following can be null.
1) Label1 (if you had missed the runat="server" in the ASP(C)X page).
2) GridView1.SelectedRow.Cells[0].FindControl("Status") returned NULL.

label1 is running at server normally, and I am loading the gridview normally, but when I want to select the data in the first cell, I cannot do that. Is that the proper declaration?

This is terrible code.

1 - are you serious with these variable names ?
2 - The places this can throw an exception are:
SelectedRow can be null
SelectedRow can have no cells
FindControl can return null
You need to write code that checks these things before assuming they have succeeded. Then you can see which part is failing, and work out why

May be they have booked both domains for the web server. We have a cursed proxy solution that allows access to URLs that it has in its catalog. 
Thanks for the update anyway.

Can you mention the error? Also, if it an article-related query, a quick posting in the article's messageboard would elicit faster responses.

hai.
here I mention the error on the Drag and drop demo project
Could not load type 'DrawingWebApp.RetrieveImage'.
Could not load type 'DrawingWebApp.SpecStorage'.
|
|
|

Is the project built? The necessary assemblies should be in the bin folder and the folder and its associated virtual directory must be marked as an application in IIS.

Hi! I want to get the row from a table and put in a label. Any clue how this can be solved. Like let's say I have a table with 3 rows, and I want to assign the values from a table to 3 labels
|
|
|
|

If you always want to use the same row or automatically determine which row you can use the grid's OnItemDataBound event and the eventArgs parameter will have a reference to the current row, e.Item.Cells[x].Text will get you the value in one cell...or if the cells are named (i.e. not just boundcolumns) you can use e.item.FindControl("name") and get the value that way, but you'll have to cast that to the correct type.
you can also use a button on the form and put your code in the itemCommand event, so the user can pick which row, agin the EventArgs paramter will contain a refernce to the row the clicked button was in.
Hope you found that helpful, Please rate helpful responses, lets us know we're actually giving good answers.
