View 5 RepliesI have a "database explorer" page that is desgined to be pointed to an unknown database and allow users to browse the data, so it basically uses the SQL system tables to develop its queries and pull in data to tables using auto-generate columns.The problem that I have is that I would like certain types of columns to have certain formats and I'm wondering the best way to go about it. I could format the column in code in the RowDataBound event I assume, but I'm wondering if there some better standard way to do this? Is there a setting of any kind that I can use? For example I want all of the datetime fields to be formated for short date, like {0:d}, I want decimal fields to have 4 decimal places, etc.
View 2 RepliesIn My project i want to use the mvccontrib [URL] to auto generate grid by passing the DataTable to the Grid. Currently Grid does not support this. Grid takes IEnumerable(Of T) and auto generate columns. Is their any way i can achieve this by passing DataTable. Or How do i convert the DataTable to IEnumerable(Of T). My DataTable is completely Dynamic i don't know number of columns or names of the columns at design time. DataTable completely dynamic number of columns are not fixed it just any DataTable. In Short i want to convert Dynamic DataTable to IEnumerable(Of T). Or Is their any better way.
1) One way i tried is using .net 4.0 Dynamic, DynamicObject and ExpandoObject I created a dynamic class as shown here [URL]. I trid passing IEnumerable(Of SampleDynamicObject) but BuildColumns() method is not able to find out the proprieties dynamically added on to it.
2) I think Second way to modify the AutoGenerateColumns() method to work with DataTable, But it looks impossible as Grid Get initialize using IEnumerable(Of T) and all the call on grid for method is using IEnumerable(Of T). So it's come down to converting DataTable to IEnumerable(Of T) and my DataTable are dynamic i don't know their structure at design time So i can't write any specific class to create a object and convert DataTable to IEnumerable(Of T).

GridView1.Columns.Count is always zero even SqlDataSource1.DataBind();
But Grid is ok I can do
for (int i = 0; i < GridView1.HeaderRow.Cells.Count;i++)
I rename request headers here but
GridView1.Columns[i].Visible = false;
I can't use it because of GridView1.Columns.Count is 0. So how can I hide them ?
I created a gridview that is made up of 4 gridviews and using a stored procedure to populate it. I create columns at runtime because the number of columns changes all the time.To make the grids editable I am adding template fields at runtime as I create the columns, this is to ensure that a user is able to edit the cells and some foot values update. Reason why I have four grids is to freeze rows and columns like in excel using javascript. The problem is that performance is very bad especially in IE, the grids take a long time to load. I am not sure if this is caused by the data load or the creation of text boxes. see some of the code below for my _aspx page:

I really don't know if this Post fit in this Forum section. But here I go. I need some sugestion to develop an ASP.NET code that generate complex IDs / Keys automatically. Let me be more understandable:
I want to create uniquelly IDs with more complex composition (kind of 18958351512783997769711... or crlu0xakecjzlgmjsgnedr55) or something link that (doesn't matter the lenght... those are only examples).
So, I can use that to set COOKIE ID's... PRODUCTS CODE ID's.... CUSTOMER's CART ID's... etc... But it need to generate uniquelly numbers. I don't know if you got my point I hope you did.
Is there anyway to auto-generate ASP.NET controls based on fields in a SQLDataSource? It is really easy to create a form in WinForms by dragging the fields onto the form. You can even determine which control will be used (like a dropdown). Is there anyway to do this in ASP.NET? I don't want a DetailsView since I need to have separate controls that are created.
View 1 RepliesMy solution has a web.config file and it works, no problem. However, when i make a change to a file in one of my projects and then build, it auto-generates a web.config file for that project. Then if I go to the file in my browser, it throws a windows authentication error. I then have to delete the web.config file and it works.Why is it auto-generating this web.config file?

View 5 RepliesI'm currently writing a web service using WCF in VB.NET.Previous web services I wrote used ASMX but I wanted to learn WCF and so far it's going well. I actually prefer the way WCF does things.One thing I miss however is the way that ASMX used to generate example SOAP requests and responses. It was like getting documentation for free.Is there anyway to auto generate SOAP documentation for WCF?
View 1 RepliesI have a report with 4 different variables await user input, these variable can be null but the problem I am having is since null is set to the default value for all of the variables the report will automatically generate itself when the user starts it.
Is there a way to halt auto generation so the user just sees the variables and the view report button other than setting one of the variables to not have a default value of null?
