you try accessing the dropdownlist like this in the event:
DropDownList list = (DropDownList)sender

and then use it.

Actually why you were getting the error because you were not been able to get the control and then was using it that why you getting that object reference.. error.
In you event just set the reference for the dropdownlist and check whether it works or not.
suppose this your method:
public void Test(object sender, System.EventArgs e)
{

DropDownList list = (DropDownList)sender;
string hh = list.SelectedItem.ToString(); //to get the selected string.

}

public void aa(object sender,System.EventArgs e)
{
DropDownList dl=(DropDownList)sender;
ss=dl.SelectedValue.ToString();----->this is working fine
TextBox tb=(TextBox)DataGrid1.FindControl("TextBox1");
tb.Text=ss;------->this is giving error

}

You can't get the textbox(which is inside the datagrid) like this. You need to have the find the index and then to find the control.
Probably first get the datagrid item like this:

TableCell cell = list.Parent as TableCell;<br />
DataGridItem item = cell.Parent as DataGridItem;

then you try to find the textbox control in it.

TextBox tb1,tb2;
DropDownList dl1,dl2;
dl1=(DropDownList)sender;
string ss=dl1.SelectedValue.ToString();
tb1=(TextBox)DataGrid1.Items[0](i was missing this).FindControl("TextBox3");
tb1.Text=ss;

thank u i got the solution

If I am not wrong, you have added this drop down in the edit Item template of Datagrid. What you can do is, You can go to the HTML source code and where there you have added this Edit Item Template you can add an event for dropdown in the HTML code itself.

<asp:dropdownlist id="DropDownList1" onselectedindexchanged="DropDownList1_SelectedIndexChanged" runat="server">

You can't activate a button that is disabled. You have to enable it first.

If you just want to post the form, you can use the submit method on the form.

There is also a built-in control ChangePassword in the ASP.NET 2.0, you may consider replace it with another name, and the Codebehind attribute is depricated in the version 2.0.

Nested repeaters Paging problem

MalikRizwan11-Sep-06 0:47

I have 2 Repeaters with ProductCategory and ProductDetail Architecture..
i.e master detail

Wot i want to do is ... enable the paging as a whole rather than ProductCategory or ProductDetail .. Here is sample code for it

strSQL = "SELECT   ProductID, ShortDesc, LongDesc, SubCategoryID, PictureUrl, ProductCatID, DataSheetUrl " & _<br />
         " FROM  dbo.Products ORDER BY ProductID"<br />
'& Request.QueryString("subid")<br />
strSqlMain = "SELECT  ProductCatID, Description, SubCategoryID FROM dbo.ProductCategory Where SubCategoryID=" & Request.QueryString("subid")<br />
clsCon.MakeDataSet(strSQL, dsProduct)<br />
clsCon.MakeDataSet(strSqlMain, ds)<br />
ds.Tables(0).TableName = "Main"<br />
ds.Tables.Add(dsProduct.Tables(0).Copy())<br />
ds.Tables(1).TableName = "Products"<br />
Dim str1(0) As String<br />
Dim str2(0) As String<br />
Dim dr As DataRelation = New DataRelation("ProductCat", ds.Tables("Main").Columns("ProductCatID"), ds.Tables("Products").Columns("ProductCatID"), False)<br />
ds.Relations.Add(dr)<br />
rptCategory.DataSource = ds<br />
rptCategory.DataBind()<br />
clsCon.sqlConnection.Close()

And the ItemDataBound Event of Master Repeater is

Protected Sub BindChild(ByVal source As System.Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs)<br />
        If e.Item.ItemType = ListItemType.Item Or e.Item.ItemType = ListItemType.AlternatingItem Then<br />
            If (CType(e.Item.DataItem, DataRowView).CreateChildView("ProductCat")).Count > 0 Then<br />
                Dim rpt As Repeater = e.Item.Controls(3)<br />
                Dim dsPaged As New PagedDataSource<br />
                dsPaged.DataSource = (CType(e.Item.DataItem, DataRowView).CreateChildView("ProductCat"))<br />
                dsPaged.AllowPaging = True<br />
                dsPaged.PageSize = 7<br />
                dsPaged.CurrentPageIndex = CurrentPage<br />
                lblCurrent.Text = "Page: " & (CurrentPage + 1).ToString & " of " & _<br />
                dsPaged.PageCount.ToString<br />
                lblPrevious.Enabled = Not dsPaged.IsFirstPage<br />
                lblNext.Enabled = Not dsPaged.IsLastPage<br />
                rpt.DataSource = dsPaged<br />
                rpt.DataBind()<br />
            End If<br />
        End If<br />
    End Sub

now problem is It makes the Paging enable on Product Repeater meanz .. if i have a Categories like CAT-A CAT-B,CAT-C
and all of these categories has 10 items each .. then paging will work as
first page will populate with 7 records of A,B,C, each .. and on pressing Next link it will show rest of records of each category ..
eg

CAT-A
a
b
c
d
e
f
g
CAT-B
ba
bb
bc
|
|
bg
|
|
|
so on
on next page
CAT-A
h
i
j
CAT-B
bh
bi
bj
|
|
|
so on

but i want it to work as
First Page should show CAT-A with 7 records
on pressing next it should show Rest of 3 records for CAT-A and ultimately start CAT-B with 5 records and so on ..
LIKE

CAT-A
a
b
c
d
e
f
g

on next page
h
i
j
CAT-B
ba
bb
bc
bd
