Hi,
I am writing a Windows Forms application.
Is there any method of finding the toolbar button currently under the mouse cursor? It seems that the button objects are not Control (class) derived...

OK - I've got it now. You're trolling. Congratulations, you had me fooled for a moment.
If this is a joke, get a life. If it's not, then I am at a loss.

I told you this was rude and inappropriate and you decided that must mean you should post it to some other forums as well ?

Odds are high that you're asking for help in using a webservice that most of us probably have not heard of. Otherwise, your question makes no sense at all. What do their docs say ? Do they have a support forum ?

Hi
I have a gridview in an aspx page.
The paging is working. But the sorting doesnot..It goes into an infinite loop..
Could you tell me what is going wrong..
Do I need to bind the datagrid after the sort function is called....
I couldn't find a correct answer so far ..
So please let me know the exact problem with this code.
Thank you
The following is the code
<asp:GridView ID="dg" runat="server" AutoGenerateColumns="false" AllowSorting="true" AllowPaging="True" OnSorting="dg_Sorting" OnPageIndexChanging="dg_PageIndexChanging" Width="447px">
<columns>
<asp:boundfield datafield="jobid" HeaderText="JOBID" SortExpression="jobid" />
<asp:boundfield datafield="jobpost" headertext="JOB NAME" SortExpression="jobpost" />
<asp:boundfield datafield="description" headertext="DESCRIPTION" SortExpression="description" />
<asp:boundfield datafield="nocondition" headertext="NO: OF CONDITIONS" SortExpression="nocondition" />
</columns>
</asp:GridView>
And I have the code for onSorting=dg_Sorting as follows
public partial class jobdetails : System.Web.UI.Page
{
SqlCommandBuilder c;
SqlDataAdapter da1;
DataSet ds1;
protected void Page_Load(object sender, EventArgs e)
{
SqlConnection ctr = new SqlConnection("data source =.\\SQLEXPRESS; initial Catalog=udus;user id=sa;password=pass123");
da1 = new SqlDataAdapter("select* from JOBMASTER", ctr);
ctr.Open();
c = new SqlCommandBuilder(da1);
ds1 = new DataSet();
da1.Fill(ds1, "JOBMASTER");
dg.DataSource = ds1;
dg.DataBind();
}
public void DataBind1()
{
SqlConnection ctr = new SqlConnection("data source =.\\SQLEXPRESS; initial Catalog=udus;user id=sa;password=pass123");
da1 = new SqlDataAdapter("select* from JOBMASTER", ctr);
ctr.Open();
c = new SqlCommandBuilder(da1);
ds1 = new DataSet();
da1.Fill(ds1, "JOBMASTER");
dg.DataSource = ds1;
}
public void dg_Sorting(object sender,GridViewSortEventArgs e)
{
string oldexpression = dg.SortExpression;
string newexpression = e.SortExpression;
if (oldexpression.IndexOf(newexpression) < 0)
{
if (oldexpression.Length > 0)
{
e.SortExpression = newexpression + "," + oldexpression;
}
else
{
e.SortExpression = newexpression;
}
}
else
{
e.SortExpression = oldexpression;
}
SortDirection direction;
direction = SortDirection.Ascending;
dg.Sort(e.SortExpression, direction);
}
protected void dg_PageIndexChanging(object source, GridViewPageEventArgs e)
{
DataBind1();
dg.PageIndex = e.NewPageIndex;
dg.DataBind();
}
}

Hi,
U cant set sorting like this.
U have to rete one function in that U can use dataview.
public void fillData(string sortExp)
{
if (Session["dv"] != null)
{
dv = (DataView)Session["dv"];
}
else
{
DataSet ds = new DataSet();
/// GET DATASET VALUE FROM YOUR FUNCTION
dv = new DataView();
dv.Table = ds.Tables[0];
}
dv.Sort = sortExp;
//// BIND DATAVIEW TO GRIDVIEW
}
Call this function from GridView sorting event.
if (ViewState["sort"] != null)
{
if ((SortDirection)ViewState["sort"] == SortDirection.Ascending)
{
ViewState["sort"] = SortDirection.Descending;
fillData(e.SortExpression.ToString() + " asc");
}
else
{
ViewState["sort"] = SortDirection.Ascending;
fillData(e.SortExpression.ToString() + " desc");
}
}
else
{
if (e.SortDirection == SortDirection.Ascending)
{
ViewState["sort"] = SortDirection.Descending;
fillData(e.SortExpression.ToString() + " asc");
}
else
{
ViewState["sort"] = SortDirection.Ascending;
fillData(e.SortExpression.ToString() + " desc");
}
}
Thanks,
Sun Rays

First You should take 2 textboxes and one button..
then write the following code Globally....
static DataSet ds = new DataSet();
static DataTable dt=new DataTable();
and in pageload event you should paste this code
if(!IsPostBack)
{
dt.Columns.Clear();
ds.Clear();
dt.Rows.Clear();
dt.Columns.Add("Name");
dt.Columns.Add("Number");
ds.Tables.Clear();
ds.Tables.Add(dt);
DataGrid1.DataSource =ds;
DataGrid1.DataBind();
}
and Write code for button1..
DataRow r=dt.NewRow();
r[0]=TextBox1.Text;
r[1]=TextBox2.Text;
ds.Tables[0].Rows.Add(r);// dt.Rows.Add(r);
DataGrid1.DataSource =ds;
DataGrid1.DataBind();

Hi,
I am using zip method provided by java.util.zip which takes input as sbyte[].I am getting response from a function in Stream.This stream is a file data.And when I am making conversion from byte[] to sbyte[] because of some Data loss I am not able to open the file which gives error like file is corrupted or damaged. I can think of some solutions but here are the problems with them-
1.> Can I convert this Stream to sbyte[],presently I am converting it to byte[] through MemoryStream.
2.> Presently I am directly putting this byte[] to Response.BinaryWrite() and its working but how to do that with sbyte[] conversion from byte[] to sbyte[] to create a zip entry and then again converting it to byte[] for Response.BinaryWrite can damage the file.
Any suggestion will be appreciated..

Hello,
I've read a lot about delegates and I understood the mechanics of creating them. What I don't get is, what situations you would use them in or what advantages do the bring.
Why would it be better to pass a delegate from classA to ClassB rather than just instantiating ClassA from ClassB and using ClassA's methods that way?
Thank you in advance.
Regards

You use them every time you use events.
robinnexus wrote: what advantages do the bring
You can pass around references to a method on an object rather than the object itself. They can be multicast, allowing you to call more than one method with a single call.
robinnexus wrote: Why would it be better to pass a delegate from classA to ClassB rather than just instantiating ClassA from ClassB and using ClassA's methods that way
What if you already have an instance of ClassA and so instantiating a new instance in ClassB would give the wrong behaviour? Forms are a good example. Say FormA is already open and you want to call a method on FormB.... you cant just instantiate another FormA as this would be a different instance to the one currently open that you want to call a method on.

hi all
i have some values on html page in javascript. i want to get that values in C#. how to do that.
I tried displaying it on a label, and retreave it from there.
This is the function in javascript
function display()<br />
{<br />
var localpath1 = document.getElementById('lblerr');<br />
lblerr.innerText = localpath;<br />
}it is diplaying the value on label. lblerr is the id of label. am calling this function on pageload
but when i try to get the value using lblerr.text, it is showing null.
y is it so?
how to get value on the label
|

innerText is a different property its not same as .Text.
Make a hidden variable in a form with runat="server" and assign it that value.
In .aspx
In javascript u can write
document.getElementById('hdnVar').value = localpath;
and in c#
lblerr.Text = hdVar.value.ToString();
Try it, It should work.
