AJAX :: Fill Grid Via Webmethod On Button's Client Click
Jan 7, 2011
I have a page with about 8 dropdowns at the top, and a gridview at the bottom. The user will select values from the dropdowns and then I want to populate the grid. I would like not to do a postback when filling the grid, so I'd like to have an html input button which calls a web method. My web method accepts an array of parameters (i.e., the dropdown values), passes these to a stored proc and returns a List (Of myClass). I then want to bind the List to the gridview. First question: Is this possible?
Second question: I need to pass the dropdown values to the web method. So I need a javascript function which looks at each dropdown, gets the value, and puts it in an array, then passes this array to my Web method. The web method needs to know which value goes with which parameter, to feed the stored proc...so am I locking myself into a situation where the ORDER of the parameters matters, and is there a better way?

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 have a service that works great on my development box. It uses JQuery to hit my web service, and then the JSON results are sent back.
The web service is located on our basePage.cs. We didn't want to put out an external WebService for this. Our on beta box something different is happening.
The web page seems to be trying to call the web method correctly - the JSON data is being sent... but the server doesn't seem to know it's a webmethod. here's my service function (it's in our basepage.cs which inherits from Page).

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>
[Code]....

I'd like to invoke a button click event on an ASP.net page programmatically, using c#. I don't have access to the server-side of the page, so i can't invoke the function directly.

This is my aspx pages button properties:
<asp:Button runat="server" ID="cmdConfirm" Text="Select
Customer"
ValidationGroup="ValidateId" Height="26px" onclick="cmdSave_Click"/
Now on my Page_Load I have:
protected void Page_Load(object sender, System.EventArgs
e)
{
Name = Request.QueryString[0];
LoadCustomer();
cmdConfirm.Attributes.Add("onClick", "update("
+ Name + ");");
Conn.Close();
}
This is my button click for Select Customer button.
protected void cmdSave_Click(object sender, EventArgs
e)
{
RecordChanges();
}
Now I must run cmdSave_Click() before the cmdConfirm.Attributes.Add even though both is for same button anyway. I know that client side script will try to run first but I must run the cmdSave_Click event first to save the data. Aftre that cmdConfirm.Attributes will send the Name to the next page using a Javascript function where the stored values(stored using cmdSave_Click) will be used. I have no other choice. I cannot run the Javascript function first as it will happen before the data is stored. And also I cannot use another page as all has to be performed in one page so that user will not have to click Save twice. Can anyone tell me How I can delay the cmdConfirm.Attributes.Add until the cmdSave_Click is performed.
