Is there a way to place the insert row below the header in a gridview instead of in the footer?
I have Gridview with Template Field.And I Put Dropdownlist at footer row of gridview. but when i insert the value from a database table in dropdownlist , than it generate error.
for filling value i declare variable like in databound event of gridview.
for example: dim varclass as new dropdownlist
varclass=Gridview1.footerRow.findcontrol("ddlClass ")
it generate error that: Object reference not set to an instance of an object.
[Asp.net / Vb.Net] How can I validate my gridview footer checkbox using Javascript. I have a gridview with footer having 8 checkboxes -(chkActive1,chkActive2,.....chkActive3) -
The condition I want to have is - The user need to check atleast 1 checkbox or else the transaction would not allow.
I have a Gridview that I create a dynamic footer wired up to the RowDataBound event.
However there is a 50/50 chance that 3 of the columns will have no data.
I want to be able to dynamically hide the columns with no data if possible.
I have tried doing this in the RowDatabound event by checking if the value is = 0 but that does not work because I think the event is called to early?
Is there anyway to refer to the values in the Footer row after ALL the data has been bound?
Ideally in VB
`Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow Then

I realise there is a solution for this but I am struggling to get it to convert to VB correctly.I have managed to get a cascading set of dropdowns with data based upon each others results which I was really pleased with.However due to the post back the grid will disappear until the second value is selected and looks awful.Is there anyway within VB to allow the header to stick around if there is no data within the grid view?

We are using VB 2005(Visual Basic.net) with SQL server as database and MS Access for the Reports. Right now we are passing the footer label from our VB app to MS Access for a selected report. If the user closes that report(not closing access) and opens another report the footer label is not being displayed. Is there any way I could send the footer label to all the reports in Access as soon as I open the database.Right now in below code we are sending the footer label just for the report selected. Is there a way to send the footer label to all the reports that are existing in the Access database.
Here is the code we are using right now.

View 2 RepliesFor my project, I need to develop an app, which will have MS-SQL db with 4 tables
a>FileHeader
b>FileFooter
c>Extension
d>Detail about the file.
This is all to do with the Magic Numbers, or File header and footer, found in all files. The first 4-byte and last 4-bytes.
Example:
Suppose a word DOC file when read using this app should return and match the values
D0 CF 11 E0
So, how can I read the files using vb.net, fileIO, FileStream/StreamClass/FileReader? I just need to open the file and read the first 4 and last 4 bytes of any given file. And then it should connect back to the SQL database and lookup for the matching values from the tables as I had mentioned. And return a match found or not found.

I am writing a VB.Net app that has need to send a file to web script.

3. Dim responseArray As Byte() = myWebClient.UploadFileAsync(uriString, OpenFileDialog1.FileName)
4. Dim response As String = System.Text.Encoding.ASCII.GetString(responseArray)
There is a problem with URI that I give, it says "Expression does not produce a value" on line 3. where "uriString" used. When I used myWebClient.UploadFile(String,String) it freeze on sending, so I found out, that to continue code execution I have to use "UploadFileAsync", but it does not provide [String,String], but it requires [Uri,String].

View 3 RepliesI've come across a problem with my program; I'm using MS Visual Studio 2010 with a VB.net application. I'm uploading a log file with .log ext to my server after my program is done running. I have noticed a lot of systems fail to upload the log file because of the firewall settings of their modem. I was wondering if anyone would know a workaround to uploading this file maybe on port 80. Here is the code I use to upload the file.
My.Computer.Network.UploadFile( _
"C:log.log, _
"ftp://www.myftpserver/logs/log.log, "loguser", "password")
Like I said this works fine if the Modem firewall in on low, but fails everytime if modem firewall is in the default setting. I believe it's using port 21 right now to upload.
