So i wondering is their any way to implement this navigation system

Transaction_Time tranTme = new Transaction_Time();
put it in the session.

DataSet dstTranTime = (DataSet)Session["Transaction"];

View 1 Repliesin my masterpage I have the following:
<asp:SiteMapDataSource
ID="MenuSiteMap"
runat="server"
ShowStartingNode="False"
SiteMapProvider="SpanishSiteMap"
/>
In My code behind I want to provide the SiteMapProvider instead of having it hard coded from the aspx page. What would the code look like to replace in thie case 'SpanishSiteMap' and have that come from code behind in c#? I thought something like this but i know this is way off. hopefully someone has a one liner code that will give provide some sleep. I've come closer to a working code. this is what i have... but get the error mentioned below.
MasterPage myMasterPage = (MasterPage) this.Master;
// do a find control on myMasterPage and find the siteMapDataSource
SiteMapDataSource mySiteMapDataSource = (SiteMapDataSource)myMasterPage.FindControl("MenuSiteMap");
// now u have the reference to the siteMapDataSource used in the master page how do I set the provider..
mySiteMapDataSource.Provider = "SpanishSiteMap";
Error: Cannot implicitly convert type 'string' to 'System.Web.SiteMapProvider'
in my webpage textbox is there in that text box provide regular expression like Ord1,Ord2,means
first three charcters alphbets,the first alphabet stat with Uppercase letter and fourth numerical value dispalyed,
and remaining no need do display any characters when user enters

I've basically got 2 applications. One is my back office application (Admin) and the other , the front end application (web site)
My problem is that, the admin uploads 'n' number of photos ,which is stored in one of the folders within my back office application and the path is stored in my DB as , for example : ~/Uploads/test.jpg.
But it is not possible for me to access this image from my front end application because the path actually exists in my back office app. How do i get to view the images that I uploaded on my front end Appn. ?

View 1 RepliesI am trying to create a list view to provide functionality similiar to the pages in this article(will end up being much simpler in my case)
[URL]
Basically I need three columns. Column 1 will be populated on page load with a list of user names and some data. Clicking on a user from column 1 will query for data regarding that user and bring back multiple rows to be displayed in Column 2. Clicking on data from a row in column 2 will return rows to be displayed in column 3. I am just curious as to how some of you guys would approach this. Ive looked at grouping templates and some articles regarding listviews with multiple rows but. Would it be easier to use 3 seperate listviews? Any ideas or articles to point me in the right direction?
i've got a gridview and sql datasource. Its connected to a stored proc that has four optional parameters. In VS when i set up the data source, if i use the test option, and dont supply any values for the sproc, it returns all the values in the table which is what it should do. Now when i try to fill the gridview, it wont return anything at all unless i provide values for all 4 parameters.
It's not even trying to search because i had sql profiler open and nothing shows up until i provide all 4 values. any idea why it's doing this? How do i get it to actually bind even if provide less then all 4 (or none) of the values?

My question is, what to do inside the detailsview update event function to able to edit and update data. My method can be wrong too.
I have a page with a table and two button with the names (Submit and Add Rows) When I click on Add Row a new row will be added to a page(This is achieved using javascript), when I click on submit button I will be doing server side validation. If I found any error the error will be displayed on the page. During this process the controls which were added by me were loosing its state. As a result I need to add the rows once again and need to fill the data and click on submit button. Can any one let me know how to avoid this and see that the controls donot loose their states. So that there is no need for me to create rows once again if any validation fails on the server side.

Till now I used to design RDLC file before and assigned typed dataset table columns.Report processing mode is local. But now my stored procedure returns different columns based on condition i.e columns are not fixed every time. Now I need to add that columns to typed dataset and dataset is assigned to RDLC file. So dataset and RDLC files are create dynamically based on stored procedure result set columns.
View 1 RepliesWhat I am thinking is this? Is it possible for me to upload the data from an excel file to dataset of my application first, so that the user can view the data in a gridview to review it first, before the user strike the save button, to save it in the database. So, that in case there is a problem, the gridview will high light all the data with an error. So the user can easily pull out the excel and correct the data before saving it in the database.
