Forms Data Controls :: Way To Set Cumulative Frequency
May 27, 2010
I have a gridview with a column holding the price of a transaction. I need another column added which will keep a running total, something like:
Trans ID Price Total
1 £1 £1
£4 £5
3 £3 £8
I haven't generated this using datasets or any back end code, I only call the results using the DataGrid controls. Is there a simple way to add this new column?

I would like to find controls in the detailsview control placed in the EmptyData Template of the gridview. I am trying to create Insert new record for the gridview control.
1. If there are existing records in the table - works fine and sets my two values: I placed Detailsview and Insert Button in the footer of the gridview. I needed to set the values of two fields. When I click on the Insert button it saves new record and sets the field with the value (code attached - works fine). I also have a popup extender that opens detailsview - this works just fine.
2, If ther are not records in the table - saves record but cannot find and set controls on the detailsview Same thing setup in the EmptyData Template. The record is saved but I cannot Find and set the field value on the control.
1. Link button (on click) in the gridview footer (works fine)
protected void LinkButton1_Click1(object sender, EventArgs e)
{
string zupa1;
zupa1 = ddlSelectEmployee.SelectedValue;
try
{
DetailsView zupa = (DetailsView)gvTraining4.FooterRow.FindControl("DetailsView1"); TextBox zupa2 = (TextBox) zupa.FindControl("txtInsertEmployee");
zupa2.Text = zupa1;
}
catch
{
}
DetailsView dettraining = (DetailsView)gvTraining4.FooterRow.FindControl("DetailsView1");
TextBox training = (TextBox) dettraining.FindControl("txtTrainingType");
training.Text = "4";
}
2. EmptyDataTemplate.FindControl - can save record but cannot access txtInsertEmployee and txtTrainingType
DetailsView zupa = (DetailsView)gvTraining4.EmptyDataTemplate.FindControl("DetailsView1");TextBox
zupa2 = (TextBox)zupa.FindControl("txtInsertEmployee");TextBox
training = (TextBox)dettraining.FindControl("txtTrainingType");"4";

Im having trouble accessing controls inside the gridview. I have a formview control on a aspx page and inside this formview i have controls that are bound to a datasource. Which works hundred percent. Also inside this formview i have a gridview which i have created my own template. Gridview1 has 3 columns with textboxes in each column.
Column 1 - LogDate
Column 2 - LogBy
Column 3 - Number dialed
Now this is what im trying to do. I have a dial button inside formview1 along with 4 textboxes which has telephone numbers in it. When i click on the dial button i want the time to be populated into Textbox1 which is inside gridview1 and at the same time Textbox2 to be pupulated with the Username as well as the number must be populated into Textbox3 inside gridview1.

In my code behind I can use try/catch blocks to deal with database errors. How can I capture and handle database errors when using a datasource with a dataenabled control? For themost part I'm using ListView and EntityDataSource controls.

I have 5 user controls in a web form. Data is being loaded into the user controls at the user control page load event. I have a single save button for the entire web form(the the top of the page). Each user control has update panel and consists of many web controls like textbox, dropdown,gridview and many other.
after the page has been rendered successfully to the user.
Considered that he has changed text in one user control ( in few textboxes,dropdowns , grid) and clicked on save button.
Now I should save only the changes user has made ( in 1 user control) instead of saving all the 5 user controls.
how can i achieve this?

I have a datagridview control that I'm using to display cache data to the end used on a web form. The issue that I'm having is that every time I re-run the application, and the cache data is re-generated... it loads duplicate data that's being displayed to the end user. I can't seem to figure out how to keep this from happening.
What I would like to have happen is that only unique data rows be returned and cached for the end user. Unless there are new data rows on the database that needs to be included in the cache data results...the previous data results should not be duplicated. I've tried to change a few properties on the datagridview control, but nothing seem to keep this from happening.

I have a listview control bound to an SqlDataSource. As part of the formatting I want to add a title to the data returned from my database. For instance if the data base returns a phone number I want to add 'Tel.' first. However I do not want to diplay this
title if the datafield is empty. Here is what I have done so far.
<ItemTemplate>
<asp:Label ID="BusinessLabel" runat="server" Text='<%# "Tel. "+Eval("Business") %>' CssClass="TeleStyle" />
Or This:Tel.
<asp:Label ID="BusinessLabel" runat="server" Text='<%# Eval("Business") %>' CssClass="TeleStyle" />
</ItemTemplate>
Business is a phone number. If the data field contains a number I get: Tel. 1234 123456. If the field is empty I get Tel. If Business is null I want nothing dsplayed, how do I do this?
