You have to use Assembly.FullName property instead of Name and I didn't understand your way to obtain type name. This works fine for me:
object o = AppDomain.CurrentDomain.CreateInstanceAndUnwrap(page.GetType().Assembly.FullName, page.GetType().FullName);

Looks like your grid item does not have two cells, or your second cell does not have any control inside.
I would say you didn't add column or textbox after postback. If you are sure you did, then put breakpoint on row where you did so to stop application there, check if textbox is in its place and then go step by step through your code and find out WHERE it gets lost. Or post code, where you add your textbox into grid and your event handler, that we can take a look what can be wrong

How can I retain the value of one textbox from one form to another within same project ?
Like suppose I have a login id page ( Form I) in which the users are going to enter their login id & password. Now on 2nd page (Form II) I want to use this value of login id to fetch some related data from database. Now, how can I transfer the value of the login id entered by the user from one form to another.
Pls provide some solution in this regard.
Thanks & regards,
Mini

You can use a session var or request & response commands, the first one is safe.

Hi,
I have problem with updating string values using GridView. After pressing edit button i insert new values into textboxes. But after update, updated are only columns, which are not string. String values become empty.
Im using Oracle database. Here is relevant code fragment:
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="Data Source=ora;Persist Security Info=True;User ID=yxo;Password=test;"
DeleteCommand="DELETE FROM Employee WHERE ID = :ID"
InsertCommand="INSERT INTO Employee (ID, First_name, Last_name, Address, Salary, Project) VALUES (Serial_Employee.nextval, :First_name, :Last_name, :Address, :Salary, :Project)"
SelectCommand="SELECT 0 as ID, '' as first_name, '' as Last_name, '' as address, 0 as salary, 0 as project from Employee UNION SELECT * from Employee ORDER BY ID, first_name DESC"
UpdateCommand="UPDATE Employee SET First_name = :First_name, Last_name = :Last_name, Address = :Address, Salary = :Salary, Project = :Project WHERE ID = :ID"
ProviderName="Oracle.DataAccess.Client">
<DeleteParameters>
<asp:Parameter Name="ID" Type="Int32" />
</DeleteParameters>
<UpdateParameters>
<asp:Parameter Name="ID" Type="Int32" />
<asp:Parameter Name="First_name" Type="String" />
<asp:Parameter Name="Last_name" Type="String" />
<asp:Parameter Name="Address" Type="String" />
<asp:Parameter Name="Salary" Type="Int32" />
<asp:Parameter Name="Project" Type="Int32" />
</UpdateParameters>
<InsertParameters>
<asp:Parameter Name="ID" Type="Int32" />
<asp:Parameter Name="First_name" Type="String" />
<asp:Parameter Name="Last_name" Type="String" />
<asp:Parameter Name="Address" Type="String" />
<asp:Parameter Name="Salary" Type="Int32" />
<asp:Parameter Name="Project" Type="Int32" />
</InsertParameters>
</asp:SqlDataSource>
Can anyone help me please?

Ok, I figured it out.
Default value for string size is 0, that's why empty strings were updated. I changed the size and now everything works fine

can any body tell me a proper method of implement paging in gridview if gridview's datasource is datareader.
I know two ways:
1. hold all records of datareader in arraylist
2. hold all records of datareader in datatable.
But these two approach required looping.Data from datareader is added to arraylist or datatable one by one so it very problematic in case of large data.
Please tell me is any way to add these records from datareader to datatable or arraylist or to anyother object directly without looping.
or other method to perform paging with datareader.

we can't do paging with datareader becoz it is forward only not backword
and it is connection oriented.

actually am designing a datagrid wich posses same appearence as inbox .
when i pressed the delete button i want to delete the records ,wich i checked (more than one).

plz give me solution..!

You just got lucky! Put the following javascript within the <head>...</head> tags in your web form:
<script language="javascript" type="text/javascript">
function SelectAllCheckboxes(spanChk)
{
// Added as ASPX uses SPAN for checkbox
var oItem = spanChk.children;
var theBox=(spanChk.type=="checkbox")?spanChk:spanChk.children.item[0];
xState=theBox.checked;
elm=theBox.form.elements;
for(i=0;i<elm.length;i++)
if(elm[i].type=="checkbox" && elm[i].id!=theBox.id)
{
if(elm[i].checked!=xState)
elm[i].click();
}
}
</script>
Then, you will have to add templated checkbox field in your dGridView, and Im hoping you know how to do that. Once you make that templated field, drag a checkbox in the ItemTemplate AND HeaderTemplate. Name the HeaderTemplate's checkbox "chkAll" and name the ItemTemplate's checkbox "yourCheckBox". Then follow the below schema for the onClick event:
<asp:TemplateField ShowHeader="False">
<ItemTemplate>
<asp:CheckBox id="yourCheckBox" runat="server" />
</ItemTemplate>
<HeaderTemplate>Select All
<asp:CheckBox onclick="javascript:SelectAllCheckboxes(this);" id="chkAll" runat="server">
</asp:CheckBox>
</HeaderTemplate>
</asp:TemplateField>
To process the checked rows through an event handler, put in a button and get the onClick event handler ready, then do as below:
protected void yourButton_Click(object sender, EventArgs e)
{
yourObject = new yourClass();
int count = GridView1.Rows.Count;
for (int i = 0; i < count; i++)
{
//access each CheckBox from the TemplateField
CheckBox cb = (CheckBox)(GridView1.Rows[i].FindControl("yourCheckBox"));
//If it's checked, process it...
if (cb.Checked)
{
//do your thing!
yourObject.doWhatYouDo(GridView1.Rows[i].Cells[2].Text); //the Cells[2] points to the data within third column, it can be anything
}
}
yourObject.Dispose();
}
Let me know if you need help

There are some set of server controls its property enabled= may be true or false,now in code behind how to find its current state and i am getting the controls id during runtime like this
foreach(Control c in form1.Controls)
{
............
}
Thanks In Advance
|
|

|

Hi,
You have to cast the control first like
foreach (Control c in form1.Controls)
{
if (c.ID == lnkLink) //where lnkLink is the ID of the control
{
LinkButton link = (LinkButton)c; //cast control object to whatever control it should be (ie. LinkButton, TextBox, etc.)
bool status = c.Enabled;
...
}
}

Dear CPians,
I am trying to enable OutpoutCache on a UserControl which is dynamically added to the page. I get an exception when I instantiate the UserControl. The code goes as follows:
DisplayTime myUserControl;<br />
myUserControl = (DisplayTime)LoadControl("DisplayTime.ascx");
If I do not have an OutputCache directive it works fine. When I add the following:
<br />
<%@ OutputCache Duration="20" VaryByParam="*" Shared="true" %>
I get the following exception:
System.InvalidCastException: Unable to cast object of type 'System.Web.UI.PartialCachingControl' to type 'TestApp.DisplayTime'.
Any Ideas?

Friends, i am new to web development and currently exploring ASP.NET 2.0.
What i want is that, whenever user clicks on a link of my page, only the part of my page gets load and not the entire page. How can i do this in VS.NET 2005 ? Some one told me that this is a concept of frames which are not supported in VS.NET. Is that true, if yes that why this feature is missing from a quality product like VS 2005, there must be certain reason ?

Of course you can use frames, but you can not work with them on server side (in ASP.NET code), because frames are pure client side stuff. You can write JavaScript to control frames and register it with your page (which is supposed to be part of frameset). I can tell you from my experience, frames are pain! If you don't need to use them, then don't use them.
