I have a asp:button in template field of gridview, I set command name for this and in grid I mention on command event. On clicking the page it shows error message is :
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

I want to prevent them from viewing other user's expense receipts. Share name: \serverAExpenseReceipt$
I have a doubt regarding displaying data in gridview. I have comma separated values in a particular field in my database. Will I be able to display the comma separated values from db table in a control in the Item template field of my gridview?
Setting up the editItem template of a gridview. I have a template field with a dropdown list for editing. When the gridview goes into edit mode the dropdown list is displayed with all the right options but the current value of the field (pre-editing) is not the selected value of the dropdown list? How do I make that happen? I have a couple fields where the editItem template will use a dropdown list and I'm sure a user will not realize those values have changed and they will just edit what they intended to edit and save the changes, inadvertently also making changes to other fields.

protected void Button1_Click(object sender, EventArgs e) { //List<Customer> customersresult = new List<Customer>(); does not match the type here CustomerWebServiceClient.Customer[] cust; CustomerWebServiceClient.CustomerWebService client = new CustomerWebServiceClient.CustomerWebService(); cust = client.GetCustomerContract(TextBox1.Text); //coming across now.. //if (cust.va) validate if there is data GridView1.DataSource = cust; GridView1.DataBind(); } // this is showing the gridview with the data coming.

I see from google that this is a common problem. I have a SQL server database that contains 26 rows of data. Two columns, the first is PK and an identity column (keys numbered 1 to 26) and the second column is a text field (nchar(10)) containing a letter of the alphabet (A..Z). The letters were inserted randomly to simulate sql being unsorted by default. I have a query that returns all of the data ordered by the letter column ascending. If I execute the query in sql server I get 26 rows orderd A..Z.
I have a gridview that is set up for paging (page size = 15) and sorting. When sorting is disabled, all data is correctly displayed on the gridview, 15 rows on the first page, 11 rows on the second page.
If I enable sorting, I get 15 rows on the first page and 11 rows on the second page, however on closer examination I find two letters missing and two letters duplicated on both pages. If I navigate to page two, then back to page 1 I find that the data is then shown correctly and the missing letters are back.
Has anyone struck this issue? I am thinking that the sort is not being initialized correctly, but am not sure where to look.

I have a gridview, whose columns I am dynamically binding. There are two fixed columns, one is a button field and another is a template field containing an image. The other columns might vary in number and behaviour, so before binding the grid, I am removing all columns of the gridview except the button field and the template field. But after doing this, if i try to do a findcontrol for the template field(Image column), it is notgetting the control. Means while removing the other columns, this image control also getting removed.Below is my code:
[Code]....
Now, after this i call the databind method. The problem is with the for loop, where I am removing the columns after the image column. And I am not able to find the control after that.In rowdatabound i am trying to find the control like this:
I have created an out-of-the-box (default everything) ASP.NET Dynamic Data Entities Web Site using VS2010, C# and the .NET Framework 4. Created an ADO.NET Entity Data Model based off a MS SQL 2008 R2 database and registered that EF data model for my dynamic data. Everything works great except for the one change I would like to make. By default, the GridViewPager.ascx file provides the values 5, 10, 15 and 20 in the dropdown for GridView's "Results per page" option. I would like to change that to 10, 20, 30 and 40 - with 40 being the default selected option.
I went to the code behind file and modified it to have the values I am wanting. Those values now show in the dropdown, and work if I select them. Problem: when the page is first rendered only 10 rows will show. How can I change this?
When I change my insert update and delete buttons to template field....they do not work properly anymore. I get a "Cannot insert a Null Value into...blah blah blah, error.

I am using an IComparer to do the sorting of the gridview and binding it to a list of objects. It used to be that the linkbutton in the first template field was being done like this:
[Code]....
The sorting worked just fine when it was like this, but I would prefer not to use a querystring value. The problem with using the linkbutton is that the sorting appears to work (there are only two rows in my test case and they change places), but when the linkbutton is clicked on it is in the same order before the sort took place. After each sort the gridview's datasource is reset to the newly sorted list of objects and the databind method is called.
