View 6 RepliesI am using a DetailsView control to allow for updating a user record. Is there a way to check if the values are actually updated/changed when the update link is clicked. I know there are users, who would click the update button rather than the "Canel" even if there are no changes to the record. So, how do I check if any value has been updated when the update link is clicked. The DetailsView uses a SqlDataSource to populate the DetailsView.

I am using seperate buttons to control whether edit and delete row linkbuttons are enabled or not on the GV. When I click a buton to enable the edit linkbuttons on the GV and then click a linkbutton for a row that puts it in edit mode. Then if the Delete button is clicked I have code that disables the edit linkbutton and enables the Delete linkbuttons. But, if there is a row in edit mode and the delete button is clicked, the edit linkbuttons disappear and the delete buttons appear (as expected) but the row that was in edit mode does not have a delete linkbutton in it and the row is still in edit mode with no update/cancel buttons. When the delete button is clicked, if there is a row in edit mode, I need to cancel any edit modes in any row.
View 3 RepliesI'm using C# and SQL Server. I have one gridview which contain 3 columns "ID, COMPLETED (either yes or no), BY (adminID that completed)" and adminID can be null.
If user selected "yes" in COMPLETED column then how can I make sure that adminID in BY column is NOT empty or adminID entered is EXIST in database.
I have a simple grid with 5 columns. The first 4 are numeric values I have formatted with templates. The last column is a total and I've added the Update button on the end. When the Update button is pressed, I have it updating the table with the new values and calculating the Total column. My goal is to have the Total column calculated after each cell is updated and not when the Update button is pressed.
I've added CommandName="myUpdateRowTotal" to
my templates.
<ItemTemplate>
<asp:TextBox ID="R01_Item_txt" CommandName="myUpdateRowTotal" runat="server" BackColor="White"
Font-Names="Arial" Font-Size="10pt" ForeColor="Blue"
Text='<%# Bind("R01_TARGET_COMMISSION", "{0:###,###,##0}") %>'
Width="75px"></asp:TextBox>
</ItemTemplate>
There is a very common problem I am facing in my new webproject in gridview control.The sequence of the execution of the process is as follows:There are some search parameters in SearchPage with a gridview. In gridview's rows there is an Edit button.By providing search parameter(s), data populated to gridview and if we click edit button a new page opens as a popup to update record.In new page the record is updated fine. On successful updation user close the window but he goes to the Search page he again finds the same record with the same parameters to see changes it remains unchanged.Its only changed when he search another record and then again provides the previous parameters.I don't know why is this behaviour of gridview?
Any idea would be helpful.
I have 5 tables as follows
as it can be seen from diagram, I have one table ie.patientdetails with Pid as primary key and other 4 tables have pid which is foreign key related to Pid in patient details.
the problem is that when if a test data is filled for say patient with Pid as 1, the data is saved nicely in required tables
If i try doing that again for same patient then a duplicate is created in test tables with pid as 1.

To Add new row to a dataset table, I am using code below. Before adding this how do I check if that row has already been added to the dataset?
Example:
Dim newCustomersRow As DataRow = DataSet1.Tables("Customers").NewRow()
newCustomersRow("CustomerID") = "ALFKI"
newCustomersRow("CompanyName") = "Alfreds Futterkiste"
DataSet1.Tables("Customers").Rows.Add(newCustomersRow)
Note: The table I am dealing with does not contain a primary key!
I need to check for duplicate records before inserting them into the SQL database.Thus I have the following codes:
For count = 0 To GridView1.Rows.Count
If (GridView1.Rows(count).DataItem("Student Name").Equals(dtDataTable.Rows(count).Item("Student ID"))) Then
lblMsg.Text = "Records Existed"
End If
but there are error message. "Object variable or With block variable not set."

View 3 RepliesI have a textbox, when ab OrderNo is entered in the textbox 3 GridViews are generated.
GridView1 has general data about the order
GridView2 has data about the items on the order
GridView3 has data about reserved/back order items on the order. GridView3 only has data if the order has items reserved or on back order.
Is it a way to check if the GridView3 has data or not?
I have tried
If GridView3 isnot Nothing then
'gets some data from GridView3
End If
But does not work. The code still goes inside the code block and returns an error when finding no data...

I have a grid view that is dynamically created.In which every cell in the girdview has a 2 textbox (cTxtboxQty,ctxtWorkOrder) and 2 label.
When user click on the cell, a pop up come out and user are able to change the text inside the cell and click save.After that the pop up close and changed data immediately reflected on the screen.
My problem is:
After my data are changed and updated to database on the pop up page and having it post back to the parent page , my dynamically created textbox in gridview retain old value even new value has been assigned to it.
This sound very weird but i have no idea how to solve this.
My client side code is as below :

I have tested many times and find out that it might be the page hold the old value in memory, so that even we have updated the textbox value, after postback, it still keep and show the old value?
I came across a situation where a user selects no of rows from dropdown , depending upon the user input, automatically that no of editable rows should appear to input data...(maximum 8 rows only)

View 1 RepliesI have a set of dataset with different column retrieved from DB. I need to present the datasets in one GridView (or other ListView etc...) without specifying the column_header. It should present automaticly since the GridView is bind to the DataSet.
In additional, I want this GridView to handle multiple rows edit and update the dataset, idealy, show data in textboxs in initially.How could I set the GridView to edit_model without hardcode column_header and textboxs in 'itemtemplate' or filed.
How could I achieve the bulk edit and update, so that I can assign 'mydataview1.table' to the dataset.
I have used the same steps that you have used on your sample for inserting, deleting and updating. This is my code
private String strConnString = ConfigurationManager.ConnectionStrings["CustomerConnectionString2"].ConnectionString;
protected void Page_Load(object sender, EventArgs e) {
if (!IsPostBack) {
BindData();
[Code] ....
It is deleting the data but not updating the data,it sticks to the same data after clicking on the update button...
