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.
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.
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?
HTML:
<asp:GridView ID="GridView1" runat="server" DataKeyNames="G_Name, Param_ID" AutoGenerateColumns="False" Width="100%" PageSize="8" AllowPaging="True" OnPageIndexChanging="GridView1_PageIndexChanging">
<Columns>

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");

But i want to set DataKeyNames  properties of grid view in above code dynamically how can do this....

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 have GridView control with a checkbox in one of the columns. When I click a button to submit, I want to see if the checkbox is selected, but when I do, it only gets "Yes" for Label but false fo Checked. I know I am accessing the column because I get the Label. Wha tam I missing?
<asp:TemplateField HeaderText="OverRide">
<ItemTemplate>
<asp:CheckBox ID="OverRide" runat="server" Text="Yes" />
</ItemTemplate>
</asp:TemplateField>
//Code Behind
//Where i = the row
CheckBox cb2 = ( CheckBox )GridView2.Rows[j].Cells[7].FindControl("OverRide");
I currentlly am trying to get a bit value from a specific cell, i can get a text value from text cell but i cant seem to fiqure out how to access the bit value. This is on a dgvRowCommand event so im using datakeys to access the row and a column index for the coloumn like so.
lblFolderRead.Text = dgvCollabFolder.Rows[currentIndex].Cells[1].Text;
This works if im trying to get a text value but obviously a bit value isnt text and thus does not return anything, How would i access a bit value in the manner above, or if it is not possible that way what other alterntives are there?

I have a Gridview X in which there are 6 columns(5 template columns that are text boxes and 1 bound field). The user has the option of changing the value in the text boxes annd saving them. There is one more GridView Y that displays DB values(all 6 columns are bound fields). Initially X will show the values that being shown in Y, and when user changes the values in Y,he should be able to save it. If we are trying this using OnTextChanged event of asp:Textbox, there is a postback everytime the user makes a change in any of the textboxes. Instead i want it such a way that all the changed values should get concatenated together and should be sent to the DB.
View 4 RepliesIn a page, there is a lable called lblTotal and a gridview with 3 columns; Name, Percentage and Amount.
Name and Percent are values that come from a database. Next I need the caluclate the Amount field. The Amount field should be set by taking the Percentage column value in each row, against the value in lblTotal and displayed in the Amount column
So for example
If the value in lblTotal is £200 and the dataset in my gridview looks like this...
Name......Percent......Amount
John......20%..........
Dave......60%..........
Mark......20%..........
Then the result would be this
Name......Percent......Amount
John......20%..........£40
Dave......60%..........£120
Mark......20%..........£40
So I guess I would need to do this using OnRowCreated and do a find control maybe?
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.
able to access the value of Gridview cells which are assigned using Javascript.
I have the following html in my gridview in an item template :
<a
href="<%#Container.DataItem("ReciprocalURL")%>"
target="_blank"
title='<%#Container.DataItem("ReciprocalURL")%>'
id="recip">
So I thought that you could use id="name" and access this just like an ASP control such as <ASP:Checkbox
or <ASP:Label etc. My code continues to caugh and state object not set to an instance of an object when I uncheck my checkbox
Line 741: ElseIf Not Me.CheckBox1.Checked Then
Line 742: Dim row As GridViewRow = gvLink.SelectedRow
Line 743: Dim recip As HtmlAnchor = TryCast(row.FindControl("recip"), HtmlAnchor)
Line 744: Response.Write(recip)

Is there a way to access the updated text property of a TextBox which is inside a GridView cell when a Wizard controls next or previous buttons are clicked? I have a requirement to not use the edit and/or update buttons on the GridView row. Therefore, I am trying to figure out a way of grabbing the updated values of each TextBox of the GridView on the PostBack. Furthermore, these controls (i.e. Wizard and GridView) are within an AJAX UserControl.
View 5 RepliesI have a gridview which has autogenerate Columns Property "TRUE", and i'm dynamically binding this gridview with columns with sql database dataset. there is no data in sql but i am successful in showing blank gridview on form, now i want textboxes in gridview attached with each column, so i wrote code in RowDataBound which generates textbox automatically and assigns ID to each textbox, nw i want to insert that data from textbox to database but i'm not getting text which is entered in those textboxes, as i am accessing that textboxes using findcontrol and passing the id like gridview1_ctl03_text0. but i''m not getting any value from textbox?
In short i want to access auto generated textbox (with out any id predefined ) values from footer of gridview
I've been searching all day for a solution to this, but nothing has worked.
Here's my scenario: I'm binding the gridview to a datatable. One of the columns is a textbox that will accept user input.
When a "submit" button is clicked, I need to loop through all the rows, get the textbox's text, and add them all together. Simple, right?
I've tried the following (this is on the "submit" button's click event):
[Code]....
The itemtemplate looks like this:
[Code]....
The txtDays.Text property is ALWAYS empty. UNLESS I assign it a value w/in the control. But then it's ALWAYS that value. I need to get the value of what the user enters.
