Asp.net - Loop Through Gridview And Get Data Key Value?


I am trying to loop through the rows of my gridview and retrieve the data key value of each row and then execute some code to run sql queries. How can I get the data key value of each row in variable? right now I am receiving an error message saying:

value of type system.web.ui.webcontrols.datakey cannot be converted to integer.

Here is my code:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
For Each row As GridViewRow In GridView1.Rows
Dim therowindex As Integer = row.RowIndex

[code]....

I have to set GridView.DataKeyNames(This is really a question about the syntax for a string array, in VB.Net.)I am discovering the PrimaryKey columns names from within a loop, ie:For Each fld As IEntityField In Me.llbDataSource.EntityCollection(0).PrimaryKeyFields'fld.Name ' this is where the column name is stored, so I have to get this into an array Next..[code]So, basically, how does one declare a string array (as required by GridView.DataKeyNames), and then populate the elements of the array from within a loop?

Password Loop Textbox - Code Works To Read The Entry Data And To Recognise The Correct Data, And The Incorrect
CODE:

That code works to read the entry data and to recognise the correct data, and the incorrect. However, even if entry is correct, the error msgbox will appear (x times of how many records there are in file), despite being navigated to the menu. Anyway that the Else isn't triggered when data is correct. Also for it to appear just one instead of (x times of how many records there are in file.)

Evaluates Loop Condition In Do...Loop Statment To Determine Whether Loop Instructions Should Be Processed
Makes the following statement about the code below:

**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.

Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?

See below.

Option Explicit On
Option Strict On

Imports System.Globalization

Getting Gridview's Row's Data?
I have a gridview which generate a link based on certain condition inside the Grid from code behind. What I want to achieve is when I click on that link, I want to catch all the information from the row that the link is in. So for example, if row 1, 2, and 4 has links in cell 5, When I click row 1's link, I want to get all the cell value from row 1. When I click on row 2's link, I want to get all the cell value from row 2, etc. I am somewhat close but not quite. When I click on row 2, I still get the same value from row 1, same as when I click on row 4, I get the same value from row In short, I want to get the row's value based on the link that's in the row. Here's my code:

$('a.SendEmail').click(function(e){
var Name = $('#<%=GridView2.ClientID%> td:eq(1)').text();
var Id = $('#<%=GridView2.ClientID%> td:eq(2)').text();

Display New Data In Gridview
I am using visual studio 2008. I have a winforms app that takes data from an xml doc. I store the data in a ms sql database that I have created via a stored procedure. When Irun the app the data from the xml doc is captured and put in the database, but I can only see old data, the data that is captured during the current session can not be seen unless I close the app down and restart it. I have tried the following, and every variation I can think of to allow me to see the new data but to no avail.[code]

Gridview Does Not Display Even When It Has Data?
Yesterday I attempted to add some code to turn one of the cells a different colour diring databinding method. When I added that code and debugged, my gridview stopped showing data.

So I took the entire method OUT...

Now my gridview does not display even when I put a STOP at the page load method, and it shows the gridview AND SQLDATASOURCE as having rows.

Traversing Through GridView Data?
I need to loop through a gridview to then compare it to my database.this is what i have now:

Dim rows As Integer = gwResults.Rows.Count()
For Each row As GridViewRow In gwResults.Rows
'move through rows and check data in each row against the dataset
cSource.GetDetails(Convert.ToInt32(row.Cells(1).Text))
Next

is it possible to get gridview values in each column by calling them by a name, instead of index? so maybe have something like cells("userID") instead of cells(5)i have many columns, and indexes could get really confusing.

VS 2008 Data GridView
I have a mdi container, that has several forms (childrens), one of those forms has only one datagridview, to show data, from an datatable...Image There're several image columns in the form.

To debug the process i created a new project only with one form and put everything working, and the images in the columns were just fine.
Then i "copied" the code to my application to the mdi children form, but the images doesn't show up.

After spending some hours trying to figure out what i was doing wrong i finally came to conclusion that the problem it's in the form/datagridview, that doesn't paint/refresh the images correctly if the form it's a mdi children...

There's something that i'm missing here? There's some event that prevent or override the images that i set? I need to put this to work, but i don't see how.

Asp.net - MasterPage Data Bind To GridView?
I have a Master Page with nested pages in ASP.NET. Fairly simply I want to databind some hyperlinks to a gridview for the master page. This however is throwing a null reference exception when I try to set the DataSource.

I tested the code on a separate page and it works as expected. When debugging I can see the Page_Load Sub hit twice, I don't know if this is the cause I have one nested page being loaded, this is a blank page at the moment

EXCEPTION
Object reference not set to an instance of an object.
MASTERPAGE CODE BEHIND
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

Asp.net - Persisting GridView Data Across PostBacks?
Alright, so here's my basic ASP.NET page setup: I've got a page with a GridView that has ContentTemplates in it. You can add a row and edit/remove rows at any time. There's a "New" button that creates a new row.

All of this data is bound to custom data objects. So if I have a GridView of "People" and each row has "FirstName", "LastName", and "Gender" (with TextBox and DropDown controls), I then have a "Person" object which has public properties for "FirstName", "LastName", etc. I have the binding set up correctly, and I can push data into the GridView from the object, and I persist the object with the Session variable. My page lifetime structure looks something like this:

Page_Load: Loads the List(Of Person) from Session()
Any events fire, and modify the List(Of Person).

After any event, the List(Of Person) gets saved back into Session(), and is then DataBound to the GridView (and any subsequent fields are also DataBound, such as the DropDownList.

My question is: Whenever I fill in rows in the GridView, and then add a new row (there is no database saving going on whatsoever), my fields clear out and don't persist across PostBacks. So, how can I persist my custom data objects with databinding across postbacks?
