I have a templated control embedding a checkbox in a GridView I have an event on the checkbox which has a loop that pulls ALL of the checked checkboxes and the associated value. I only want to pull the datavalue of the checkbox that I just checked but the properties/methods associated with that checkbox event are not giving me any sort of index or item.value from which to do this.
View 2 RepliesI am currently adding checkbox functionality to a system. I would like to check a group of users and add them into a db table. I currently have the administrator values flowing into the db table fine but it will not insert the empID into the table from the gridview. Here is my code:[Code]....
View 5 RepliesI use a gridview with products, in which one column lists the manufacturer, and the next colum lists the item number.This gridview works fine, but now I want to add a product image on the same row. Instead of using a stored image location, I simply want to make a link to the image like this:
"www.mywebsite.com/images/manufacturer/itemnumber.jpg "where the manufacturer and the itemnumber are the same as displayed in that particular row in the manufacturer and itemnumber columns. I am not versed well enough (yet???) to reuse the data from those two columns.
I'm trying to pull a value from a Gridview so that I can create a running subtotal. I've looked at a number of examples but they all seem to fail.
Why does this not work? Each and every reference I try to make to the cells "value", comes up null.
Sample code1:
[Code]....
Sample code2:
[Code]....
In sample code 2, I get the "header text" for the column...but I know the value in the cell...so it fails on a data conversion.
I have a GridView, bound to a table (Meals) in a SqlDataSource.
Into that GridView, I have added a TemplateField, which contains a DropDownList (which displays the numbers 1 - 10, added manually; no Data Binding). And, I've added a ButtonField.
When I click the Button, I want the values of some of the GridView rows PLUS whatever value was selected in the DropDownList to be pulled out and stored in a second Sql table (Orders).
Pulling the rows bound to the SqlDataSource is easy but JavaScript is needed (I think) to pull the SelectedValue from the DropDownList. I understand women more than understand JavaScript (that's how little I know) and the code below has been kindly offered by another forum user who is at a loss, himself, now.
Here's the code and the error message I'm getting.

Using a class component, an Object data source and a formview I am successfully pulliing data from a SQL database. In some cases the rows contain one or more Null values and I would like them to be ignored completely. My simple code follows:-
<%# Eval("add_1") & ","%>
<%# Eval("Add_2") & ","%>
<%# Eval("Add_3") & ","%>
OUTPUT:-
Rose Cottage, 123 New Road, Margate,
not quit sure where I've go wrong with this but hopefully someone might have an idea why this isn't working:
This what I thought would work:

But it's not! what I get for the OnClientClick attribute is: "DeleteRowKey=<%# dataBinder.Eval(Container.dataItem, "idx_mstrWord") %> "
I've tried several variations (EVAL, BIND, specifying the container and not specifying the container),
none of which gives the expected results; OnClientClick="DeleteKeyRow=12345"
If I add a label and set the text to: <%# dataBinder.Eval(Container.dataItem, "idx_mstrWord") %> I get a number which is what I should but if I try to get it to embed it so my cleint script can work with the data all I get is binding command.
What am I doing wrong? I really don't want to have to kludge around with some hidden field and then have to search through the grid to get at this data key. I need this key on the client side in order to provide additional details in my confirmation popup modal.

View 2 RepliesJust to be sure.. ive added a GridView and i was wondering if it was normal that it is generated as a floating element? Because, i had to use a clear: both after in order to write on the next line.. cause the text was displayed at the right of the GridView even with a <br>.
View 4 RepliesAccessing GridView Element of specific row?
GridView1.DataSource = newDs;
I am trying pull a table from a sql datasource which is very wide. And therefore, I want the pager element (i.e Prev and Next) links to be left aligned. But when I try to add the "align attribute, it says not permissible attribute for pager.
Is it even possible to do that or do I have to stick with centered pager?

So I thought that you could use id="name" and access this just like an ASP control such as <ASP:Checkbox

I just wrote something small up with a GridView databound to the products table of the northwind database to play around with the control. I added a template field and put a checkbox in it, ProductID, ProductName, and UnitCost. I can successfully loop through the GridView and find the rows that have the checkbox checked, and can get ProductName for each row, but keep erroring out on ProductID and UnitCost. It's probably something small, but I just cannot figure it out.Here is what I have so far:

I've created a data bound gridview to a SQL database. I am retrieving the data with a simple select for a specific date, and then populating my gridview. The one caveat is that I have added a second header row to my gridview, and then I am hiding parts of another row that was retrieved to only populate the main header row. I believe that this is causing my issue. However, when I step through the code it appears that my ids are proper (the first row has an id of 0, etc....). However, when I check the checkbox in row 4, the actual data from row 3 is being pulled out of the gridview.

I am loading data from Datset into gridview.I have a a checkbox in my grid.

Here are the following i need to add to my table:
1. based from my stored procedure once i get the value of employeeid and passed it to @eployeeid it will add the cutoffid, idnumber, teamid, date, shiftid, schedulein and scheduleout
stored procedure:
[Code]....
2. How can I get the cutoffid that was first add to the table getting it to another table
3. How can I get date, schedulein,scheduleout? shiftid will be chosen on the dropdown(know the code), then the date will coming from dates between my datefrom.text and dateto.text value? how can I make an array loop for this, then concatenate the date and timein/timeout from shift table just by getting the shiftid
my shift table is
shiftid, shiftname, timein, timeout
ex 1, 7-3, 7:00am, 3:00 pm
so the array will look something like this
if datefrom not equal to dateto, counter+1
date + timein = schedulein
date + timeout = scheduleout
until reach the dateto
4. IDnumber will come from usernamelogin.employeeid compare to employeeid employeetable. how will i code this?
