I need to update a column of a record. I am using a FormView control to provide the UI for the SqlDataSource.

The update method MUST be called from a button, rather than the built in "Update" feature of FormView1_ItemCommand, (unless there is a way to call this event with a command on the button control.)

I am attempting the SqlDataSource update by:

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

SqlDataSource1.Update()

End Sub

and:

Protected Sub SqlDataSource1_Updating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceCommandEventArgs) Handles SqlDataSource1.Updating

Dim totalcost As Single = 400

e.Command.Parameters("@TotalCost").Value = totalcost

'SqlDataSource1.UpdateParameters("TotalCost").DefaultValue = totalcost

End Sub

Neither the e.Command.Parameters("@TotalCost").Value = totalcost or the

SqlDataSource1.UpdateParameters("TotalCost").DefaultValue = totalcost has any impact.

Any help would be greatly appreciated....thank you

why don't you create a sql stored procedure, send the parameters and update the table which you want to be updated. It's really easy to update a field programatically.
Check this link for more info regarding stored procedure and this link for playing with stored procedures in asp.net
hope that can help, Laziale

Hi,

I have created a C# ActiveX control and I am trying to access its properties and methods using javascript exactly as described in this mini article http://www.c-sharpcorner.com/UploadFile/dsandor/ActiveXInNet11102005040748AM/ActiveXInNet.aspx

However, I fail to access any properties/methods of the control and the javascript does not display an error msg

Any Ideas? Thank you

And ever has it been that love knows not its own depth until the hour of separation

Modal forms in VB.Net

Can anyone direct me to a GOOD, THOROUGH example of using modal forms in VB.net? I've Googled it but I can't seem to find anything that works. They always seem to leave out some important parts. I'm relatively new to VB.net and I need some real guidance, not just partial snippets.

This is ASP.NET forum so I am assuming you are talking about modal dialog box.

If you want to use jQuery dialog box then following link will help.

In case you want to use the standard javascript dialog box then please refer following link.

Blank page problem with Web Parts

Hi
I am running a simple, single page asp.net website with four webzones with two user controls within two of those zones. One user control contains a calendar and the other contains an image control.

(This is just an exercise from 70-562 training kit - ASP.NET 3.5)

I am using the asp.net dev server built into VS2008. The first time I run the app the page display fine, but if I close the controls in the page (aka as the end-user might) while the app is running, exit the browser and restart the app, the second and subsequent times the page appears blank. (Refreshing makes no difference.) Even if I close, exit VS and reload the app, it still runs with a blank page from thereon.

The behaviour appeared to be that IE8 is retrieving pages from the cache rather than the response, but I've cleard the cache, etc.

I deleted the project and re-wrote it from scratch and it again ran fine, until I closed the controls when the app was running, so this would seem to indicate a problem that is occuring <i>after</i> the ASPNETDB.MDF database in App_Data folder of the site has been built!?!

Anyone else had this issue?

I believe the need to AJAXDatepicker will be because you don't want a server side picker!
In that case, as suggested above, pick any client side datepicker. There are few at this very site also.

Further, if you are getting some error with one you have, looks like error is pretty straight forward and you should be able to resolve it. Or is it not your code and you are stuck up?

Thanks for your prompt response. I am grateful.

Now if I want to use a button to get the value on the LinkButton, what do I do because I cannot find FindControl method on a DataList.

Thanks for anticipation.

u can find linkbutton by this

for (int i = 0; i < DataList1.Items.Count; i++)
{
LinkButton lnkValue = (LinkButton)(DataList1.Items[i].FindControl("lnk_name"));

}
