View 1 RepliesI have a page with a simple textbox, when an OrderNo is entered in te textbox the page is populated with 2 or 3 gridviews depending if the order has items reserved or on back order.
GridView1 has data about the order, like status, payment details.
GridView2 has data about orderitems, each row displays an item from the order with stock and order quantities
GridView3 has data about backorders, each row displays an item from the order with quantity reserved and quantity on back order. As is no data for GridView3 if order is not on backorder I thought that I can enclose my code inside an if block
if GridView3 isnot nothing then
'getting some data from the cells in GridView3
endif
but the code still executes.

View 1 RepliesI would like to check if a particular value already exist in the database Gidview row. If the value already exist, tell the user that he has already entered the record and don't save. otherwise save the record. In my case I want to check the "Random number".
<asp:TextBox ID="txtRandomNumber" runat="server"></asp:TextBox>
Maybe it could be done with a foreach loop statement.

I use a ItemDataBound for a repeater.But i use 2 kinds of linq querys to bind it.Some of them has a MerkID, and some doesnt have this item.So its easy i need to do this:
if(e.Item.DataItem.Contains("MerkID"))
{
//Code for linq query 1
} [code]...
So of course the if selection doesnt work, but how can i do that? I already tryed this:
DataRowView drv = (DataRowView)e.Item.DataItem; if (drv.Row.Table.Columns.Contains("MerkID"))
But that doenst work because he cant convert it to a datarowview because its a linq class.So what to do? Right now i use a try and catch, but there are better solutions i guess...

I have a SQL database that creates a record for every document uploaded by the user to the server. I want to check this table before a user uploads a document to ensure they don't upload a file with name that already exists.
I know how to make the connection and make the SqlCommand to query the table for an existing record. But I don't know how to check the record count from the sqlCommand I made.
Does that make sense?
Using myConnectionCheck As New SqlConnection(myConnectionStringCheck)
Dim myCommandCheck As New SqlCommand()
myCommandCheck.Connection = myConnectionCheck
myCommandCheck.CommandText = "SELECT * FROM Req_Docs WHERE Doc_Name =" & DocName

View 1 RepliesI have a asp:Button and asp:Textbox on Default.aspx page
Code is as below:
<asp:Button ID="Button1" runat="server" Text="Save" Width="80px" CommandName="Update"
OnClientClick="EnableDdlCompany();saveButtonClick();" CommandArgument="Save" OnClick="btnSave_Click"/>
<asp:TextBox ID="txtBarcodeNumber" runat="server" MaxLength="11" Width="230px"
Text='<%# Bind("BarcodeNo") %>' Display="None"
OnTextChanged="TextChanged" AutoPostBack="true"></asp:TextBox>
On button click, I want to call a javascript code to check that If the entered BarCode Number in Textbox already exist in Database, then show an alert "Number already exist" else allow user to save and navigate to Default2.aspx
I can able to do the same checking on TextBox OnTextChanged event using c# code, as below:
protected void TextChanged(object sender, EventArgs e) {
TextBox txtbarcode = fvIPRForm.FindControl("txtbarcodenumber") as TextBox;
if (txtbarcode.Text.Length > 0 && txtbarcode.Text.Length < 11) {
string error = "The Barcode Number " + txtbarcode.Text + " is invalid, the barcode length must be 11 character.";
ScriptManager.RegisterStartupScript(this, typeof(string), "Successful", "alert('" + error + "');", true);
[Code] ....
Here, IPRRequest is the class/.dll file name and IsValidBarcodeTest is a function defined in the class file
But same checking I tried using the c# code on button's OnClick="btnSave_Click" event, but dont know why this event is not firing, I guess due to CommandArgument on button, but I am not sure.
That's why I want to achieve it using Javascript.

View 6 RepliesI have a GridView on a page for maintainance of the database (mdf). Under this GridView1 I have a FormView1 where I use the ItemInsertTemplate to Insert new rows in my database (which shows the data in GridView1).
