You need to run it on your webserver/database server or on some machine that is tha is always running and have access to database to read the information.

What he means is, its a paid for web host, not his own server, and I wouldn't expect them to allow windows services to be installed by anyone, hence the problem.

I am new to .net developement..stuck with an issue..
I have 2 grids in a page...Maingrid( key:- EmpID) and a Childgrid (key:- EmpID,PeriodID)

For Each Maingrid details there will be one or more corresponding Childgrid details. When user selects a Maingrid detail record (ie, when selecting a row), corresponding Childgrid detail will be loaded in the Childgrid …(same as dependent grid.)

How to load the 2nd grid according to the 1st grid row selection?

protected void rdg_Maingrid_ItemCommand1(object source, GridCommandEventArgs e)

    {
        if (e.CommandName.ToString().ToUpper() == "RowClick")
        {

            //code for retrieving corresponding data in the budget grid..
 
        }
    }

and I have delete ,edit options in both the grids.
Anyhelp will be appreciated.

In this example it shows gris in a row..but in my scenario, two different grids are there.I dont know how to bind data in to the 2nd grid according to the row selection of the first grid..

I am using telerik rad grid.

I dont have much idea about telerik grid.

But in rdg_Maingrid_ItemCommand1 event you can find the row of main grid and accordingly you can fetch the record and bind it in child grid.

Problem with checkbox binding in DetailsView

lvq6843-May-10 22:37

Hi.

I have a detailsview with a checkbox. This checkbox´s state should be determined from a ObjectDataSource which "fills" the detailsview. And, if the checkbox´s state is changed by the user, the ObjectDataSource´s UpdateMethod should of course save this new state.

Problem is, that i dont know how to bind this checfield, since the 'Checked' attribute only takes true/false, and my data is in xml. Therefore i only have "true"/"false" data as strings.

So how do i bind this checkbox state? And save the new state when the user changes it?

Thanks alot!

<code>

<asp:DetailsView ID="dvTaskDetail" runat="server" DataSourceID="odsTaskDetail"
CssClass="detailgrid" GridLines="None" DefaultMode="Edit" AutoGenerateRows="false"
Visible="false" Width="100%">
<Fields>
<asp:TemplateField HeaderText="Send mail?" HeaderStyle-Font-Bold="true">
<EditItemTemplate>
<asp:CheckBox ID="txtNotify" runat="server" Checked='how to bind it here?' > </asp:CheckBox>
</EditItemTemplate>
</asp:TemplateField>

</Fields>
</asp:DetailsView>

</code>

what is the data type of your field you want to bind?

Re: Problem with checkbox binding in DetailsView

lvq6844-May-10 1:00

lvq684

4-May-10 1:00

The data type is string. The field contains "false" or "true". And should be bound to the checkbox´ checked attribute which takes boolean.

Thanks!

Try This

Checked='<%#(Eval("Field").ToString() == "true" ? true : false) %>'

Thanks alot!
But it did not solve my problem.
With this solution, i can DISPLAY the correct data (if the box are checked or not). But when the user updates the data (changes the checked state), the ObjectDataSource´s UpdateMethod sees the field as null.
Is there a workaround on this? Smile | :)

"Sys.WebForms.PageRequestManagerParserErrorException" while using AJAX

Hi,

I have an issue relating to AJAX Confused | :confused:

. I have an AJAX enabled webform where I have various controls and one button among them requires to open a new page (.asp) which should have all the controls of the source page.

I have achived this functionality. but after a new page opens in new window, my source window started giving error on any control change. THe exact Error Message is:

Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled

One scenario I can understand is, I have used

window.document.formrs.action = "Test.aspx"; // New Page in New Window
            window.document.formrs.target = "_blank";
            window.document.formrs.submit();

when going to new page, and when returning, it is set back to

window.document.formrs.action = "RS_Test.aspx"; // Source Page
           window.document.formrs.target = "_self";

Because of this, my viewstate might be changing thus Response is modified... D'Oh! | :doh:

I need to completely eliminate chnaging Form.action property for some reasons. Please help..... Sigh | :sigh:

Thank You.

Anand Desai

The error occurred not because there some problem with your code.

It is because .NET Framework does not handle the request validation and the exception is thrown.

For more information refer following links, it will solve your problem surely.

Thanks Jinal,

The thing is, I have resolved the problem by overriding "Render" method and the error disppeared. Thumbs Up | :thumbsup:

Thanks a lot for all inputs. Rose | [Rose]

One another issue is I have an classic ASP Page I am traversing from AJAX Enabled .aspx page. And I require all the controls (basically whole page) in that .asp page. . Confused | :confused:

In this scenario,

1) "PostBackUrl" is not applicable.
2) "Session" is not useful also because I will not get ASP.NET session in classic ASP.
3) Talking about Querystring and Cookie is pointless.

Can you suggest something to achive this??? D'Oh! | :doh:

Thank You.

Then there is only one thing that will help you to do so is Javascript.

There is around two ways to do that.

1. You can use hidden fields to store the values and then access it on second page.

2. Second way is shown in below link.

http://www.boutell.com/newfaq/creating/scriptpass.html[^]

However you can also go for following links, may be help you more.
