Asp.net Gridview quanity and total column

Posted By:      Posted Date: October 18, 2010    Points: 0   Category :ASP.Net

Wow, so i know this really shouldnt be this hard to do, but im having the hardest time finding information on this that makes any sense. i am using linq to get data from my SQL server 2005 database and bind it to a gridview. From the table i am pulling two fields...Reference(the item name) and Cost. In the gridview i have added two additional columns, Quantity and total. I need to allow the user to change the quantity field to the amount they need to order and update the total field for that row. Also i would like to show a grand total at the bottom of the gridview summing all the total fields. The totals need to be updated as soon as the the user clicks or tabs out of quantities field. Here is the code for my gridview.

Tooltip for GridView Column Headers (ASP.Net)

I just wanted to add auto tooltips for my GridView headers. There are couple of ways but I don't want to use javascript and wanted to use simple 'title' attribute. It took couple of hours to get the working code supporting sortable columns. I thought it will be very useful for others. Here's the code and logic behind it.

Show grand total running total in GridView Footer

In many scenarios we need to display Running total as well as Grand total in GridView footer. In this post i will try to explain in an easy way that how we can display running total & Grand total in a GridView footer combindly. To explain this solution using an example here i use a sales order report. The report contains all sales order amount in a tabular way. I will use a GridView to display sales order amount and use GridView footer to display Running total & Grand total. Let we have a customer table with id and name column plus an orders table with OrderID,CustomerID,OrderDate & Amount. Now our goal is to show all customers order with amount as well as page wise running total & grand total. Note that running total is necessary when you enable paging in a GridView where as Grand total is always you can consider.

Use a column as parameter for a sds in another column; gridview


Hola, I have a gridview which is bound to a sds which returns 7 columns and I added two columns from the GUI.  What I want is to fill up the 9th column with DDLs and these  DDLS will get their data from a different sds which is using a stored procedure with a single parameter.  I created the 9th row, used template field, made the sds for 9th row, the stored_procedure, threw a DDL in Item template and all  I need now is to pass a parameter in the first column to the sds in the 9th column.  I can code this but i'm getting tired of aspx.cs :) and would like to do it from the GUI.

Rendering data with HTML tags in the DD Gridview for a selected column


I am having trouble finding out where and how to HTML Encode a cell's data on the Dynamic Data (v4.0) gridview of List.aspx.  As a simple case, suppose I have formatted cell data that is A<br/>B in the DB.    Obviously, I want A stacked on B in the cell.

It seems gridView1.HtmlEncode = true has gone away.

So maybe I'll try to catch it on the RowDataBound event:

protected void GridView1_RowDataBound(Object sender, GridViewRowEventArgs e)

            if (e.Row.RowType == DataControlRowType.DataRow)
                // Html Encode the cells


but this event never fires?

Has anyone figured out how to properly render HTML tags data in the List.aspx's GridView1? 

If I figure this out, then I can add a MetaAttribute called something like [EncodeAsHtml(true)] and be on my way.  Thanks!

Calculating GridView total using JavaScript/JQuery


Hello everyone.

One month ago I've had very nice conversation with a asp.net forum member asking about issue regarding calculation of GridView textboxes total using JavaScript. The main thing was to allow user to manually write values in the text boxes (placed inside GridView column) and if the value has changed automatically to perform calculation on client side.

At the end of the conversation, we came up to two solutions. The first solution was using plain JavaScript, but since I thought it was not so robust, and in order to make it more robust we would need to write few more functions. Therefore, I have simply proposed another solution using JQuery which came up much better, more robust with less code.

In this blog post I will show both of the solutions and will provide step by step explanation on how we did that.

Note: I'm using VWD.

sum of 7 column totals in footer of gridview

I have implemented column tolals in the footer of my gridview using the technicque described in this article http://aspalliance.com/782 .Now I would like to have a total of the 7 column totals that are displayed in the footer.  Can anyone tell me how to do this.  I would like to display this in a label or an addition row in the footer if that is possible.

Sorting a DVWP by Column Total

I have a survey list in Sharepoint 2007, which from what I understand means I can't add a calculated column. In this survey list I have some number columns that need to be calculated for display. They are: (1) Number of Weeks, (2) Number of Hours per Week, and (3) Number of Hours for Credit. In Sharepoint Designer, I've created a Data View Web Part which displays those columns and two additional "calculated columns." Scare quotes because the calculation is happening in the XSL of the web part, not an actual calculated column. These columns are (4) Number of Hours (Column1*Column2) and (5) Eligible Hours (Column1*Column2-Column3). I have the data view grouped by @Author (Created By) and a column total row for each group. I even figured out how to get column totals for all four columns though the nodeset is grouped by Author, which breaks out of the box. Great, beautiful. The final step is sorting the entire view by the column total of Column5. In other words, I want my groups of @Authors listed in descending order by their Total Eligible Hours. Is this possible?
