My suggession is you can add link buttons for first,next,previous and last in the footer and write appropriate codings.
If there is any other option means please tell me also.

public void Checkbox_CheckedChanged(object sender,System.EventArgs e)
{
CheckBox chkbx=new CheckBox();
chkbx=(CheckBox)sender;
if(chkbx.Checked==true)
{
foreach(DataGridItem dgi in DataGrid1.Items)
{
((CheckBox)dgi.FindControl("check")).Checked=true;
}
}
else if(chkbx.Checked==false)
{
foreach(DataGridItem dgi in DataGrid1.Items)
{ ((CheckBox)dgi.FindControl("check")).Checked=false;
}
}
}
And The Html Code Should Be
<asp:DataGrid id="DataGrid1" style="Z-INDEX: 101; LEFT: 352px; POSITION: absolute; TOP: 136px" runat="server">
<Columns>
<asp:TemplateColumn>
<HeaderTemplate>
<asp:CheckBox Runat="server" AutoPostBack=True Checked="False"
OnCheckedChanged="Checkbox_CheckedChanged"></asp:CheckBox>
</HeaderTemplate>
<ItemTemplate>
<asp:CheckBox ID=check Runat="server"></asp:CheckBox> </ItemTemplate>
</asp:TemplateColumn>
</Columns>
</asp:DataGrid>
I think this code helps you.

ASP.NET will show weird results when pressing enter key. In classical ASP programming this can be achieved by putting different forms for controls. But by generally ASP.NET won't support multiple server forms. So you need to go with some javascript. I have documented this problem clearly here[^]. You can use the class library provided with the article.

No predefined libraries available. You will get some third party libraries. Check in sourceforge.

U cannot fill the dataset with null value of dataadapter.
the problem is with retrieving top value.
mySqlDataAdapter = New SqlDataAdapter("Select top 1 * from tblsalarydetails where empid='" & _
eid & "' and (datepart(yyyy,edate) < '" & Val(ddlYears.SelectedItem.Value) & "' or (datepart(yyyy,edate) = '" & _
Val(ddlYears.SelectedItem.Value) & "' and datepart(mm,edate) <= '" & Val(ddlMonth.SelectedItem.Value) & "')) order by edate desc", sqlconn)
mySqlDataAdapter canot be null

Hi all,
Can we change the position of controls in clientside.
consider in an example.
In panel1 their is textbox firstname
panel2 their is textbox lastname next to this thier is a button btnup
if user clicks button btnup then
The panel2 i.e textbox lastname has to move to position of panel1(top) and panel1 has to come below panel2..
lastname has to come first and firstname has to come below..
thanks in advance

This can be done by AJAX more suitably
but if you want to do with javascript you can do
you want to do at client side :-
Then add one more panel with textbox ,...
hide first panel and show third one after button click
Thanks and Regards

How can i include files when i have a master page?
Here is the logic:
Page 1 -------------> Page Check ------------> Page 2
Now, before the user can go to Page 2 it must be check first if the user has the rights to the page...
I have a master page which confuses me. Anyone knows how to tackle this?
|
|
|
|
|
Your page will be in the Master page content place holder
put your all validatiion in the page 1 event (When you want to check )
master page should contain only the common things that you want to show in your application such as header footer Menu etc
Google Master page that will more helpfull for you
Thanks and Regards

Hi All,
I am programmatically creating a datagrid bound columns (in ASP.NET 2.0). During initial page load there is no problem but after the postback i am getting following error.
Error Start --------------
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.
Error End --------------
I know that in order to avoid event validation we can set the following parameters in the config file.
enableEventValidation="false" validateRequest="false"
but since there can be a risk of a hole in the security i do not want to go with that.
Hence i am using the following code to register my event during page render stage.
protected override void Render(System.Web.UI.HtmlTextWriter e)
{
foreach (Control control in this.Controls)
{
Page.ClientScript.RegisterForEventValidation (control.UniqueID);
}
foreach (DataGridItem grdRow in grdvwCheckbox.Items)
{
Page.ClientScript.RegisterForEventValidation(grdRow.Cells[0].UniqueID);
}
base.Render(e);
}
Since i am getting following error in the trace.
Error Start--------------
[ArgumentException: 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.

System.Web.UI.ClientScriptManager.ValidateEvent(String uniqueId, String argument) +2080220
System.Web.UI.Control.ValidateEvent(String uniqueID, String eventArgument) +106
System.Web.UI.WebControls.Button.RaisePostBackEvent(String eventArgument) +32
System.Web.UI.WebControls.Button.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) +7
System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) +11
System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +33
System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +5102
Error End -------------
I suppose that there is a problem with the item command buttons in the datagrid (Cell[0]). Hence i am registering those buttons also but still i am getting the error message.
I also have 2 hidden fields but since i am registering all the controls guess that should not create any problem.
Please let me know where am i going wrong.
Regards,
Anees

Goto viewsource and check what is the link. You can check in the status bar also when mouse points over the link. Check there it is coming like page'3.aspx
