If you are new in asp.net, then you may have forgotten to define a (runat="server") attribute for any client-server interaction whereever it may count in your program.

Hi..
I have a DropDown which is populated from a Project table. This table has a foreign key a Stage table which also populates another DropDown. Both Databindings occur in the Pageload event.
Each Project can have many stages, but each stage belongs to one project.
I have set the AutoPostBack Property of the DropDown for the Project Table to true. Here's what I need to implement:
1. Load page. Default Project is auto selected on the Project DropDown. Therefore relevant Stages are listed in the Stage DropDown.
2. Select another Project from the list. The Stage DropDown will automatically change to show a list of the stages available for the selected Project.
Please help. Any suggestions will do.
PS. I know I have to place some code in the ddlSearch_SelectedIndexChanged method. I just don't know what though.

What you need to do is populate the first drop down list(project) in the load event of the page. And on selectedindexchanged event populate the second drop down list(stage) with the values corresponding to the project selected.

It works fine now =D
Although I also wanted the Stage DropDown to populate at Pageload. So I just made a copy.
Thanks again.

Hi
i have a form in which i have three panels. panels are set to 'true' or 'false' according to requirement. I am having a problem that whenever i go from my last panel to first panel, i get the following error
'ctl00_cphProps_Summary' is not null or not an object'
Summary is the ID for ValidationSummary control.
i am using atlas in that page too, but not in the panel which is creating that problem. when i use updatepanal of atlas for that panel, it starts working fine, but as i am using a fileupload control in that panel too and it doesnt work with updatepanel of atlas. so i have to do something with or without updatepanel in such a way that i can not have any kind of problem in anything.
can anybody suggest me the way to come out of that problem.
regards

BData bd = new BData();
sql = "SELECT P.PartId, P.PartNumber as PartNumber, P.PartDescription as PartDescription, L.LOBDescription as LOBDescription, C.PartCategory as PartCategory";
sql = sql + " FROM PartsDetails P";
sql = sql + " LEFT JOIN LOBDetails L ON L.LOBId = P.LOBId";
sql = sql + " LEFT JOIN PartCategoryDetails C ON C.PartCategoryId = P.PartCategoryId";
sql = sql + " WHERE P.IsDisabled = 0";
//sql = "SELECT PartId ,PartNumber,partDescription FROM PartsDetails WHERE IsDisabled = 0 and LOBId=18";
DataTable dt = bd.Select(sql, "PartInfo");

You can reload the page on click of the server control. What is the problem you are getting in that?

The better idea would be to reload the page with serverside code. But if you want to use reset method then you can use it like this:
document.form1.reset()
Here form1 is the form name.

button.attributes.add("onClick","resetForm();")
step- 2
function resetForm(){
//window.document.Form1.reset();
//document.form1["Invoice"].reset();
document.form1[0].reset();
//document.clear();
}

I have some pages that require authentication. I access these pages using HTTPS...
I have set my session timeout to 60 minutes:
<authentication mode="Forms">
<forms name="Online" path="/" loginurl="..." protection="All" timeout="60">
<sessionstate mode="InProc" cookieless="false" timeout="60">
However, the system is very unreliable. Sometimes, I get logged out of secure pages after 5, 10 or 15 minutes on inactivity.
Would be grateful if someone could inform why the system logs me out after inactivity which is less than 60 minutes.
P.S
In my code-behind page, I use:
private void Page_Load(object sender, System.EventArgs e)
{
//if not authenticated if (!Context.User.Identity.IsAuthenticated) {
Response.Redirect("....");
}
}
So actually I never use the login page as specified in the web.config file

Have you declared the datagrid correctly i mean and also check that you are doing anyspelling mistakes. C# is case sensitive.

Means it is working fine if you are not executing it in debug mode, right?

ya ...
but want to remove that alert 'Error on page'...
cause i came to know that it is creating problem in DataBind()....
|
|

|

I dont think that that part would be creating the problem, can you send code for that, so that it will be traceble.
