You can try for incremental page load.
Don't load all 400 rows at once. Instead, load first few rows first, then append the rows to the GridView using ajax.
Hope it will help.

In my opinion, the difference of time is due to the ViewState usage. Have you tried to put all the 400 rows in the grid without putting any data in the ViewState? Or even try to disable the EnableViewState from the Grid control.
Even if you need the ViewState, you at least can check if the problem is caused by the viewstate or not.
As I see:
You load all records into the grid, with generates real data (the HTML of the grid) and put data into the ViewState.
Then you put the DataTable you used to do the query also in the ViewState, and at the end you have a huge ViewState that causes all the problem.

Yes, u can create ur own user control and use that in ur aspx page like other asp controls.
But u have to register ur control (either in each page or in web config).
u can use <%@ Register TagName="tagname" TagPrefix="tagprefix" Src="~/usercntrl.ascx" %>
in top of the aspx page and use ur user control
<tagprefix:tagname id="test1" runat="server">
Hope it helps u

Thanks for the reply
I know how to create and use the ascx controls but i want to add extra functionality to it
let me try and explain it in another way.
I want to make like for e.g. the asp panel it would be used like this
<asp:Panel ID = "panel1" runat = "server">
<table>
<tr>
<td>
<asp:Button id = "b1" runat = "server" text ="Click Me" />
</td>
</tr>
</table>
</asp:Panel>
now what i want to do is like the same way you use the panel to place something inside , i want to use my custom control
just again , its a popup window and i would like to use some sort of place holder where i can place stuff in
for e.g. i would want to use the window for error messges or to put in a few textboxes and labels.
like this
<tst:mycontrol runat ="server" >
<content>
<table>
<tr>
<td>
<asp:Button id = "b1" runat = "server" text ="Click Me" />
</td>
</tr>
</table>
</content>
</tst:mycontrol>

If it's a popup, it's a seperate window, not a control.

Hi all,
I have a html editor,i bind the value from the DB to the textarea.then i update the binded text and assigned it another variable.But the varible holds the value which is initially binded.I cant save the Updated text from Html editor.
Can any one help me..
|

|
Can you pastered this code? DB it's bind ,and update it.
|
|
|
|
|
Can you post the code? From your question, I doubt whether you are using web application or not. You may be binding the text area control in the page load. Now this binding code may have been written outside if(!IsPostBack) region. So, whenever you are clicking on the update button, postback is happening and control goes to the page load and it si rebinding the old value to the textarea. So, if you are doing so then put the data binding code inside !IsPostback region.
Either you love IT or leave IT...

use Javascript friend...
But if then mind that you cannot find that in the server, you need ajax to post data of those controls.
Use :
var elem = document.createElement('input');
elem.type = 'text';
divelem.appendChild(elem); //divelem will be the container which holds the textbox.

masterpage has a content place holder in it .. If you add a masterpage, you must take into account that every control in contentplaceholder will change its identity when rendered in the client.
Please let me know what kind of errors you are getting. If it is related to client side, I think you need to change the javascript codes accordingly for each controls.
We dont have the facility to change the clientId now, it is included in .NET 2010.
So there is no way out to change the id of the controls that will be rendered in client side.

Oh,there are some OCX on master page, Maybe upload used OCX samed of master page COX.

hi everyone!!!
i am using calendar control when i display the calendar i should dispose the previous dates.(or strike off)
sowmya
|
|
|
|

Use the day render event to find the dates and then strike out...e.g.
protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)
{
if (e.Day.Date < (System.DateTime.Now))
{
e.Day.IsSelectable = false;
e.Cell.Font.Strikeout = true;
}
}

Its very easy to do that, Just folow:
In your HTML:
<asp:calendar id="Calendar1" runat="server"
ondayrender="Calendar1_DayRender">
And in your code-behind:
protected void Calendar1_DayRender(object source, DayRenderEventArgs e)
{
if (e.Day.Date.Day < DateTime.Today.Day)
{
e.Cell.Controls.Clear();
e.Cell.Text = e.Day.DayNumberText;
e.Cell.BackColor = System.Drawing.Color.SmokeWhite;
}
}
It will Disable any date before today.
Hope you will get it..
