Add New Row To Grid View Using Button
Jun 8, 2010
I am working in ASP .net 2.0. I am a learner. I have a grid view which has a button in it. find the asp mark up below
[Code]...
I was thinking that when I click the command button, it would fire the mygridview_rowcommand() but instead it threw an error as follows:
Invalid postback or callback argument. Event validation is enabled using 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 am doing a online web application whereby user is able to enter in new template as well as search for template. The Add template is located outside the grid view and if user clicks on the button, it will load the grid view that is populated with data as there is a row of empty fields at the bottom. However when I click on the Add Template button, the grid view does not appear.
This is my business logic that I used it to search for records as well to click on the Add Template button to add in new records:

I'm using a grid view to display a number of records from a database.
Each row has an Edit Button. When the button is clicked I want an ID to be passed back to a funtion in my .cs file. How do I bind the rowID to the Button field?
I've tired using a hyper link instead but this doens't seem to work because I'm posting back to the same page which already has a Permanter on the URL.
<asp:GridView ID="gvAddresses" runat="server" onrowcommand="Edit_Row">
<Columns>
<asp:ButtonField runat="server" ButtonType="Button" Text="Edit">
</Columns>
</asp:GridView>

I have a link button thats text value is populated from a dataset value retrieved from a database. When the user clicks on this link button I want to somehow capture the text value. The trick is the linkbutton is within a usercontrol, and I want to do the processing from the user controls parent.
I may be able to do this via javascript with the OnClientClick;

I have added a template field in a gridview. In that i have added a radio button. I have written a code which will get row Id of GridView of a row which is having a radiobutton on it checked. Through code i am getting even name of that radio button, but it is showing me that radio button is not checked, even when it is already checked. Here is the code. Dim row As GridViewRow Dim rd As RadioButton Dim rowId As Integer = -1 For Each row In GridView1.Rows rd = CType(row.FindControl("radio1"), RadioButton) If rd.Checked = True Then rowId = row.RowIndex Exit For End If Next Even when a radio button is checked the code never enters the if block.

I have a grid view with each row as a link button. When I click on the row, some data parsing process takes place (about a 15 sec process). The grid refreshes itself at a regular interval. I want to disable the link when it is clicked once, so that the user gets to know that row has been processed already and does not click it again, until the grid refreshes itself and the row disappears. I am copying my gridview code below. how to disable the link button on that row as soon as it is clicked.
