I tried EncodeUrl() function earlier, but when i Decode that i cud'nt get the querystring , Plz tell me how to decode the querystring.
|
|
|
|
|
There is a method called HttpServerUtility.UrlDecode. Maybe you give it a try...
|
|
|

Hi, query string is a variable that you can pass to another webform
like this
in your webform1
button event: response.redirect("webform2.aspx?VAR=" & textbox1.text)
if you want to get the your variable
Webform2 load event: textbox1.text = request.querystring("VAR")
Hope this one can help.
Thanks

fill a DataView as dataset to the gridview.
DataView has Sort and FILTER options.
In Word you can only store 2 bytes. That is why I use Writer.
|
|
|
|
|
but this will remove all the other rows and i want all the rows to be displayed and the selected row in the current view.
|
|
|
|
|
Hi, do you have source code? pls post it.
you can try
sqldataadapter da = new sqldataadapter();
datatable dt = new datatable();
da.fill(dt);
grid1.datasource = dt;
grid1.databind()

Hi, you can Add in your grid a image field.
<asp:GridView ID="GridView1" runat="server">
<Columns>
<asp:ImageField>
</asp:ImageField>
</Columns>
</asp:GridView>
then this imagefield have properties to call the image from your database.
like: DataImageUrlField = dr("image").tostring();
Hope this one Can Help
Thanks

Add the tag in the Gridview like this.
<asp:GridView>
<Columns>
<asp:imagefield dataimageurlfield='<%# DataBinder.Eval(Container.DataItem, "imagepath") %>'/>
</columns>
</asp:GridView>
Where imagepath is the Column of the Dataset having image path.
This will automatically display the image when you will bind the dataset to gridview.

I am facing a very critical issue associated with AJAX asynchronous postback. I am really running short of time for releasing the product.
Let me explain the scenario here.
We are supposed to create a web application to export data fetched from database to an excel file and download at client machine. And as we have specific request from client to use ajax popup for implementing this, we have used Ajax Modal Popup and a progress bar to show the status of the process and a download link button to invoke download, both contained in Update Panel.
.Net Framework : 3.5
Ajax Version : 3.0.20229.0
We have implemented this as folows:
<contenttemplate>
<cc1:modalpopupextender id="PopUpModalPopupExtender" targetcontrolid="PopUpDiv" runat="server" xmlns:cc1="#unknown">
PopupControlID="pnlPopup" DropShadow="False">
<asp anel="" id="pnlPopup" runat="server">
<asp:image id="imgGlobalProcessing" runat="server" imageurl="~/App_Themes/MyApp/images/progress.gif" xmlns:asp="#unknown">
Progressing ...
|
br mode="hold" />
<asp:linkbutton id="hlnkExcel" runat="server" text="Excel" onclick="hlnkExcel_Click" xmlns:asp="#unknown">
<triggers> <asp:asyncpostbacktrigger controlid="hlnkExcel" xmlns:asp="#unknown">
--Code Behind--
private void ExportToExcel(DataSet dsExport, string[] sHeaders, string[] sFileds, ExportFormat FormatType, string FileName)
{
MemoryStream stream = new MemoryStream();
try
{
response.Clear();
if (FormatType == ExportFormat.CSV)
{
response.ContentType = "text/csv";
response.AppendHeader("content-disposition", "attachment; filename=" + FileName);
}
else
{
response.ContentType = "application/vnd.ms-excel";
response.AppendHeader("content-disposition", "attachment; filename=" + FileName);
}
XmlTextWriter writer = new XmlTextWriter(stream, Encoding.UTF8);
System.IO.StringWriter sw = new System.IO.StringWriter();
CreateStylesheet(writer, sHeaders, sFileds, FormatType);
writer.Flush();
stream.Seek(0, SeekOrigin.Begin);
XmlDataDocument xmlDoc = new XmlDataDocument(dsExport);
XslTransform xslTran = new XslTransform();
xslTran.Load(new XmlTextReader(stream), null, null);
xslTran.Transform(xmlDoc, null, sw, null);
//reads to a stream
byte[] byteArray = Encoding.ASCII.GetBytes(sw.ToString());
stream = new MemoryStream(byteArray);
// Buffer to read 10K bytes in chunk:
byte[] buffer = new Byte[10000];
// Length of the file:
int length = 0;
// Total bytes to read:
long dataToRead = 0;
dataToRead = stream.Length;
response.Cache.SetCacheability(HttpCacheability.Private);
response.Expires = -1;
response.Buffer = false;
length = stream.Read(buffer, 0, Convert.ToInt32(stream.Length));
response.OutputStream.Write(buffer, 0, length);
response.Flush();
stream.Close();
response.Close();
}
catch (ThreadAbortException Ex)
{
string ErrMsg = Ex.Message;
}
catch (Exception Ex)
{
throw Ex;
}
finally
{
if (stream != null)
{
//Close the file.
stream.Close();
}
response.Close();
}
}
But while running the application we are getting the following error:
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.
As a solution for this I tried different techniques which i have listed below.
1. Set EnableEventValidation=false for the Page.
2. In the Application error event i put the Context.ClearErrors()
3. Disabled the cacheRolesInCookie in roleManager in Web.config
4. Used the Response.outputstream.write() instead of Response.Write() method
5. Cretae an iframe in the ascx control
I am really finding myself in a helpless situation. I would really appreciate any help on this.
Thanks in advance

Oohh! A pyramid scheme.
If you are using SQL Server 2008 use the HierarchyID type - that is designed exactly for what you want.
If this doesn't help then I suggest you ask in the correct forum. You asked a database question, not an ASP.NET question.
