how can I specify DataKeyNames for a GridView when using a dictionary as DataSource?
[Code]....
In this example I would like to use "cat", "dog", "llama" and "iguana" as DataKeys for the four rows.
From what I understand within the Gridview Object you can have many datakeynames.
I have the field like this DataKeyNames = "id1, id2"
However, i don't know how to access the DataKeyNames individualy. For example. How do you access the first ID for the for a given row or the 2nd ID for a given row????
I have specified DatakeyNames for a GridView control in my aspx page.I need to retrieve the Datakeys in javascript.How can this be achieved?
View 4 RepliesI have two columns in my Gridview marked false for the visible property but which are clearly listed in the DataKeyNames that are still getting set to null in my database table on update.
The first one is a column MId# which is a type int. It starts as 0 but on edit is turned into null. The Second is RequireSKU which is also converted to null.
I have a gridView, with two DataKeyNames: MemberID, and CommitCustomerID.
One DataList has this sql statement:
SELECT * FROM [tblMemberProfile] WHERE MemberID = @MemberID
It pops up perfectly fine.
I also have another DataList with this statement:
SELECT * FROM [Incidents] WHERE CustomerID = @CommitCustomerID
I know this sql command works I have tested it with my data.
However I dont think the DataList is getting the proper value for the selected row in this DataLists case.
How can I make sure when I select the row in the GridView the proper parameters are going to the proper DataList sql statements?

Since I am using 2 DataKeyName is Gridview, so I have to pass both the DataKey while deleting Row from Gridview(using "Image Button" of Gridview).I tried it using below lines:
string name = GridView1.DataKeys[gvrow.RowIndex].Value["G_Name"].ToString();
string id = GridView1.DataKeys[gvrow.RowIndex].Value["Param_ID"].ToString();
I am did Gridview delete and rebind data using json and jquery like this
<script type="text/javascript">
$(document).ready(function () {
$(".deleteGridRecord").click(function () {
//Get the Id of the record to delete
var record_id = $(this).attr("id");

I have two listviews. What i want to do is that when the nested listview emptydatatemplate shows i want to put a hyperlink with a querystring in it, the id in the querystring should be the fk in the nested listview. Is it possible to bind the hyperlink with the id in codebehind? I use two object datasources. Does it matter where i put the nested listview now i have it in the parents itemtemplate. Also it seems to be a problem to set the datakeynames in the nested listview, what could be the reaso for that.

When the page is displayed have labels, textboxs, and dropdownlists on top part of the page then the gridview at the bottom with the page numbers at the bottom of the gridview. Create the columns and add data to the gridview programmatically with several hidden columns. Use DataKeyNames on the source page and use DataKeys in VB.Net code behind to get data from the hidden column cells of the selected row. On the
first page when a row is selected, the textboxes and dropdownlists have thecorrect information from the gridview hidden columns. When select another page from pages numbers at the bottom of the gridview and select a row from the new page, get theinformation from the hidden column from the first page andcorrect data from the columns that are displayed onnewly selected page.

I found a example of this but it wont work for me. So I will do a clean question by asking how do I bind a dictionary to a repeater?
I work with code behind so its for the OnItemDataBound. My Dictionary look like Dictionary<string, string>();
I'm new to c# and .net but I think what I'm trying to do is fairly simple, however I think I'm getting stuck on variable types.So I have say 6 literal webcontrol myReq1, myReq2, myReq3.... and rather than implicitly setting them line by line I just want to run through a loop and set them dynamically. So to do this I've set up a dictionary that will contain the name of each literal, I can then run through those to add the data. This all works when I set up the dictionary by hand ie
Dictionary<int, Literal> myReqDict = new Dictionary<int, Literal>();
myReqDict.Add(0, myReq1);
myReqDict.Add(1, myReq2);[code]...
Obviously the Text inserted would be dynamic too, but you get the idea, so all that works just fine, but I'd like to do the Add part of the dictionary dynamically as well and that's where I'm running into trouble, I want to do something like:
Dictionary<int, Literal> myReqDict = new Dictionary<int, Literal>();
for(int cnt = 0; cnt<7 ;cnt+= 1){
myReqDict.Add(cnt, "myReq"+(cnt+1));
}
However this isn't valid, I can see why the "myReq"+(cnt+1) would not be valid as it's a String rather than a literal, but how can I convert the String to the Literal? What I am confused about is why the cnt on Add also isn't accepted, it is typed as an Int so to my mind it should be accepted
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 I can not use this syntax.
GridView.DataKeyNames = new string() { "PowRatHP", "Voltage", "Phases", "Poles", "Drive" }
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?
I have a generic List which is populated with an object which has properties like FirstName, Surname etc.
If I bind a gridview to the list with autocompletecolumns = true, the Gridview displays the data in the List.
The code looks like:
[code]....
My question is:
How do I populate the DataKeyNames with the properties (FirstName, Surname) contained in the object that is contained in each element of the Generic List?
I have defined the following in my gridview markup (simplified):
<asp:GridView ID="grvReport" runat="server" DataSourceID="odsReport"
AutoGenerateColumns="False" DataKeyNames="EntryDate,EmployeeNumber">
Then I define my datasource's update parameters as such:
<UpdateParameters>
<asp:Parameter Name="ID" Type="Int32" />
<asp:Parameter Name="IsJustified" Type="Boolean" />

I have a MultiView control with 3 View controls inside it.
View1 contains a GridView control with 2 DataKeyNames assigned.
View2 contains a FormView and a DetailsView control.
View3 contains several DetailsView controls.
When a row is selected in the Gridview I'd like to update View2 to show data relating to the selected row DataKeyName 1 and View3 to show data relating to the selected row DataKeyNames 1 and 2.
I have previously tried configuring the SQLDataSource to use a WHERE clause setting the Source Control to the GridView object but I couldn't get it to work. There was nowhere to state which DataKeyName to use as the parameter.
I have ListView control on my page, and i bound it to Dictionary<string,DataTable> generic.Now i'm trying to put DataPager on my page to support paging, but DataPager doesn't work properly, in particular, I have to click twice to move to next page, or first few records repeating thru every page. What's the problem, what am I doing wrong? I used ListView control before with ObjectDataSource and it worked just fine. Now I'm using Entity Framework to retrieve data frm Db.
