. I am using EAV that means the is no Fixed Column name, so the Binding of the Grid Should be Dynamically.
I have a Select All checkbox in my grid that calls this function...works fine. Outside of my grid I'd like to use another checkbox for something else, but when the select all checkbox in the grid is selected, it also selects my checkbox outside of the grid. Is there way to make the checkbox outside of the grid independent from the ones in the grid?
When I edit in a asp file, the intellisense does not work for any ADODB objects with vs2008(sp1) in Windows 7.For example:Set conn = Server.CreateObject("ADODB.connection") .. And next line I keyin "conn". Then keyin ".", but it does not popup the intellisense menu for ADODB.connection.But, the native objects for asp, such as Request, Response, Session, Server.. etc., them popup the intellisense menu correctly.Or some other objects, such as "CDO.Message", them work fine !
have some Objects, lets say Employee and Role defined as below and I have defined relationships in my database that gives me a list of objects say employees and thanks to my framework each employee object also has a Role object linked via the RoleIDID, UserName, Password, Email, RoleIDRoleID, RoleNameSo in code I can do something like this
I know how to bind a simple objects to a dropdown list. However I am having problems binding my objects which contains sub objects to the control.i.e. with simple object i just do ddl.DataValueField = "myproperty" with my objects they contains sub objects which i want to bind. I have tried ddl.DataValueField = "sub-object.myproperty" which doesnt work.
firstly a static class only ever exists once and is not an instance. Any static members (ie static int NoOfPeople;) is stored in one place and is shared between all sessions (like the old global variables). Now static methods is where i'm not 100% sure. If I have a static method that doesn't use any other static members could this cause inconstant results, example (this is a fairly pointless method but just a quick example of the top of my head)
[Code]....
So in this example if two sessions (or threads) were to call this at the same time - would they both get back the expected results, because the method only uses private data (a, b and totalToReturn).Im sure this sounds a little simple but I will be using static methods to build user objects and various other objects that there will have to be a 100% garentee that the objects will not get mixed up between sessions and the wrong things return to the user.
I am using a grid control from ComponentOne and I had asked their support how I can call a VB code routine when a row is clicked on. They said no such event is available but gave the following code below. In the code below it looks like they are calling the "alert('click')" code when a row is clicked for client side. Is this right? If so, how can I call a routine in the vb code with this? I know this example is C which I can change over. I need to get data from a couple cells on the row that they click and run some vb code.
Code:
> What event is fired when i click a row so I can run code on the .vb code page? Such an event does not exist. You can handle a click on client side using RowCreated event handler:
I'm not sure the best way to explain this but I want to take results from a stored procedure and list them but not in a grid. I am listing user profiles and I want to display a picture, name, description and other info from each record. But I want each in a group. How is this done in asp.net?
I have placed a gridview control with a sqldatasource control in a modal popup window powered by ajax. I do not want the sqldatasource control to databind until I click the button to show the popup. How can I do this? I know how to prevent the sqldatasource from binding using a session such as cancel the selecting if the session is not set.

I have a GridView in ASP.Net 3.5. I added BoundFields as columns, set DataField and Header Text. Total I have 6 columns like that. Although I set "AllowSorting=True" in design view, when I run this page, all the columns didn't have hyper link that I can click on it and sort that particular column. I bind this column at code behind by using datatable. gv.DataSource = dtDispatch gv.DataBind()

How to go about creating a grid/table that can updated at run time by the user and can also be printed and exported to Excel. I have the print function working and I know how to export datagrids to Excel. Im going to attach an example to explain more clearly what Im looking for. Is this possible with a datagrid?
I'm working on a project in which we have a database, data layer (entity framework), business layer and web/UI layer.I want to use ASP.NET Dynamic Data for the web layer, but don't want it to access the data layer or database, as I want it to be purely running off business logic, and not directly accessing the data.However, it appears that Dynamic Data only allows Linq-to-SQL or entity framework data sources to be used.Has anyone used it with business-layer objects instead?
Lets say I am doing a shoping cart. I authenticate the user with a session variable.For example:
If(Request.IsAuthenticated) // Here I want to add to the shoping cart. // Can I do the following Session["Cart"] = "Washing Machine"; Now will this Session["Cart"] value which is washing machine here be unique to diff customers?

If VS 2008 and VWD 2008 are both installed on the same machine, will they both use the same Projects folder to keep my projects in?If so, can I open the projects and run them interchangeably with VS2008 and VWD 2008? This is the folder that is located at " User>Documents>Visual Studio 2008>Projects
Have a GridView with a templated select button hidden and using
e.Row.Attributes.Add("onclick",Page.ClientScript.GetPostBackEventReference(this.grdMaster, "Select$" + e.Row.RowIndex.ToString())); to select a row .
When user like to update the datasource he will select one row from gridview then in selected indexchanged event i would display the selected row values beneath the form under the grid , Then user will update the contents displayed from grid and click an update button which is outside the grid . After updating the displayed row , i got to get the values of the next row in the grid and display them for next updation , i'e if users maually selects row 3 from grid then he can update the values using the update button and then on update click itself i'll have to display next row contents of row 4 and this process could go on .
I have Parent/Child Grid (also called Nested Grids).
Parent Grid (PG) :: PG has two template fields. 1st template field has "Category ID" and 2nd template has Child Grid
Child Grid (CG) :: CG is populated in PG's RowDataBund event based on "Category ID". In CG's DataBound event, I am doing something which I need to display in CG's footer row.
Problem :: In the footer row of each CG, I have to show the "Category ID" which is in PG' row. How can I get hold of the PG's row which hascurrent nested grid (there will 'n' child grids, one for each 'Category ID' in the PG ) so I can read the "Category ID"
I was thinking if I could do something (DataBound event of CG) like this..
string catId = ChildGrid.Parent[get the index of the current row in PG].Cells[0].Text;
In a ASP.NET application I have a paging RadGrid which shows up textbox in each row. Outside the grid, there is an OK button to save the content of all the textbox. If user changes text in any one or more of the textbox and without clicking on the "OK" button, tries to move to a different page number (of the grid by clicking on the page number), he should be prompted for confirmation of save or cancel the changes.
I am guessing that one can write a Javascript function which would look for any form input control (textbox in my case) and detect changes and If there are changes, would prompt the user. However, I am not sure where I can call this function from?
I am using RadGrid but I guess this should be applicable to GridView as well.
and here is my code that parses the xml and tries to bind the grid. What am I missing here?
var retVal = service.GetTripDetailsByTripID(tripId); var xmlTrips = XDocument.Parse(retVal); var tripTolls = from t in xmlTrips.Elements("TripTollCompleteDC") select new { TripTollId = (int)t.Element("TripTollId") , DMSLaneModeID = (int?)t.Element("DMSLaneModeID") , HOVOnly = (bool)t.Element("HOVOnly") , CreateDateTime = (DateTime)t.Element("CreateDateTime") , ConfigVTMSDelaySeconds = (int)t.Element("ConfigVTMSDelaySeconds") }; grdTripDetails.DataSource = tripTolls; grdTripDetails.DataBind();
I realize these are anonymous types. Is that a problem? I have verified the service is returning the Xml as stated above. Can anyone out there point me in the right direction? Just for completeness, here is the grid markup <asp:GridView runat="server" ID="grdTripDetails" />
