Hi,
How do i make the gridview, or at least certain fields editable at runtime.
I'm manually binding data to a blank datagrid.
I know prdefined columns in the grid have a readonly property, but that property is gone in runtime!
please help.
Regards,
Tintin

You set what controls should be used in the EditTemplate of the datagrid, in the case non-editable fields just use a label. At runtime you can set the EditItemIndex to put that row into edit mode

Hello,
I am trying to edit and update data in a GridView Control so I handle the RowEditing Event to set the GridView.EditIndex so the edit appropriate controls appear. I add the following code in the event handler:
protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
{
GridView1.EditIndex = e.NewEditIndex;
}
The problem is that when I click the edit button the edit controls doesn't appear except when I click it once more and I can't figure out why is this happening.
Can someone tell what is going on??
Thanks

You must add a method to refresh the grid like this:
GridView1.EditIndex = e.NewEditIndex;
UpdateView()
-----------------
void UpdateView()
{
GridView1.DataSource = datasource;
GridView1.DataBinding();
}
Good luck!

Hi,
Plz can somebody help me what to do to get the sales tax amount in a shopping cart. That is in US they have a different sales tax for different states. So we cant calculate it manually.

There is no easy way to do it, you are going to have to find a list of sales taxes and lookup the proper rate for the users indicated state.

Not sure, I understand you clearly, but from my understanding,
you should define your submenu in a separate div, and giv that div a bigger z-index than the one of the menu's div

sir,
Which class should be imported to get the Register Startup Script .
|
|
|
|
|
It is there in system.web.ui.page

Sir,
There is no error
But when i write page.
Then the Register Startup Script is not comming.
|
|
|
|
|
In .net 2.0 it's under Page.ClientScript.Registerclient... etc.
|
|
|
|
|
Use this to put the client side script:
Page.RegisterClientScriptBlock

Hi,
Is there any way (Server side/Client side) to know any of the server control in a page is edited by the user.
I am having a situation in my project where I want to enable my save button only if user edit any of the control in a page(There are many controls in the page).
Please show me the right way. Thanks in advance.
Thank You,

If you want to do it client side then one way could be you can all the initial data in array and can compare prior to go to the server.

Hi Apurva Kaushal,
Thanks a lot for the quick response and information.
Can you please provide me some code snippet as an example.This would help me.
Thanks again,

You can use hiddenfield to store the data and in javascript you can compare with the current value and do the operations.

I'm having a bit of a reocuring problem that I just cant seem to get my head round.
I want the output of an SQL query to be placed into an XMLDocument (for use as a source for an ASP.NET XML tool).
At the moment my SQL query outputs using: FOR XML AUTO, ELEMENTS
But I dont really have any experiance using the XMLDocument and was wondering how I should go about getting the output from the SQL query into the XMLDocument??
Is there a simple way of just "shoving" it in there or is it an intricate element by element process ?
Thanks.
