Accessing gridview cell values

Posted By:      Posted Date: October 02, 2010    Points: 0   Category :ASP.Net

Hi All,

In my application Iam using GridView, in this there are fields (Quantity, Price, Amount) the user can enter Quantity Field value which is a template field (textbox). Iam calculating Amount(Quantity * Price) using Javascript and assigning to the Amount Column cells as below

Gridviewcell.innerText=Quanity * price.

and when user clicks on the Save button I want to add these details of Gridview to the database.

when I try to access the values of the gridview using below code

For i=0 to GridView.rows.count-1

GridView.Rows(i).Cells(2).toString ( for Example)

Next i

It is not displaying the changed value instead it is displaying the default value before calculating the amount.

Before implementing the Javascript part, I had done this in the code behind and it was working fine... Now I just dont want the page to get load so I used javascript.

Can any one help me out in able to access the value of Gridview cells which are assigned using Javascript.

Accessing a row's dropdownlist values AFTER the gridview control is in Edit mode

Hello, I have a gridview control. When it goes into Edit mode, there are 3 dropdownlists in one cell that are populated by separate stored procedures during the RowDataBound event. The 1st dropdownlist's value is used as a parameter to determine what the 2nd dropdownlist is populated with. The 2nd dropdownlist's value is used as a parameter to determine what the 3rd dropdownlist is populated with. Everything works fine when the row is first put into Edit mode. While I'm in Edit mode and I change the selection in the 1st dropdownlist, how do I access the control so I can feed this new parameter to the 2nd dropdownlist? I have the first 2 dropdownlists set for AutoPostBack so that the Page_Load event is fired when the user changes a value. I know how to get access to these controls via the FindControl method when the row is being databound but how do I find the control during the Page_Load event? Thanks for any help!!!   Penny

accessing values from a database with datalist?


I have a datalist and I am filling it using a dataadapter, dataset. So in my .ascx page, I have

<asp:datalist runat="server" id="dlProducts" repeatcolumns="2" repeatdirection="horizontal">


<table border="0">

<tr><td><%# Eval("Item_Name") %></td></tr>

<tr><td>I have to add a picture here</td><td><%# Eval("First_Name") %></td></tr>




In the area where I have put a statement like "I have to add a picture here", I have write a big case statement.  Like:

Case: 6 // show a picture from file1

case: 7 // show a picture from file2

Case 8: //show a picture from file3


So How do I do this here?  Because I dont know how to access the datalist values from code behind.


Here is my code behind:

SQLString = "SELECT First_Name, Picture, item_name, item_id from table1 where item_id = " + request.querystring["iid"];

dataadapter daItems = new dataadapter(SQLString, "connection_name");

dataset dsItems = new dataset();

keep values in textbox in gridview whilst paging

Hi,   I have a gridview in my webpage which has paging enabled. There are around 5 textboxes in a row and when I enter some text and then move to another page and move back to the page I entered the values in, they are not lost. I have enabled the viewstate in the gridview. I have implemented a datatable to my grid which should hold the values in the viewstate. This worked before I added paging. Please can someone offer some advice as to how I can maintain the values in textboxes whilst moving between different pages? I have tried searching it but I can't seem to find any relevant info.   Thank you very much.

ASP.NET GridView help!! Need to be able to scroll an individual cell up and down.

Hi everyone.  I have an ASP.NET GridView displaying the below grid.  As you can see, the column on the right has a LOT of text and it stretches the column.  I need to be able to set a fixed width for JUST that column (maybe like 200px) and have vertical scroll bars on that cell so the user could scroll down to read the rest of the text, is that possible to do?Here's my markup: <asp:GridView ID="GridView1" runat="server" DataSourceID="SqlDataSource2" AutoGenerateColumns="False" AllowPaging="True" AlternatingRowStyle-Wrap="False" CellPadding="4" ForeColor="#333333" GridLines="None"> <RowStyle Height="30px" BackColor="#EFF3FB" /> <Columns> <asp:BoundField DataField="Customer_Name" HeaderText="Customer" SortExpression="Customer" /> <asp:BoundField DataField="Status" HeaderText="Status" SortExpression="Status" /> <asp:BoundField DataField="Module" HeaderText

Build xml file from gridview values on button click

We are looking to add GoogleMaps to our application. With that said we are going to be using the geocoding api to pass in the lat and long values to pin point locations on the the map. Reading thru the documentation we can pass in the values via XML, so we would like to see how we can take the lat and long values from our gridview and pass that to the API if and when somone clicks on the button to show the map.. The process will work like so, you arrive at the search page, you complete a search, in most if not all cases, you will always get multiple results presented in a gridview. If you should to view them all on the map, you click button and it needs to map out each location on the map. So is there anyway to pull from the gridview the lat, long and description to pass into the API?   Any links to sites that i can review would be great. thanks. 

How can I replace values in GridView returned from a Stored Procedure

I am working on creating a stored procedure that will output a pivot table.  In the pivot table will be either the string NULL or a number.  How can I reformat this in ASP.NET so the NULL value becomes a blank cell in the gridview and the number (whatever it is) becomes an 'X' ?
