Forms Data Controls :: How To DataGrid SelectIndex Inside A DataGrid

Sep 22, 2010

Simply put... I want to duplicate the example found at this link, in rather than C#.


I would like the selectedvalue of the dropdown to display additional data base on its selection in multiple text boxes.

I have tried using the DropDownList OnSelectedIndexChanged property, within a DataGrid EditiItemTemplate, but I cannot retrieve data from the selection. (AutoPostBack is "True"). I can however use a button onclick event to fire a "prre-defined" selection value.

Forms Data Controls :: Delete Confirmation Box In Gridview With Edit And Delete Buttons?

Nov 18, 2010

How do I reference the delete button to add the delete confirmation box when I have both the Edit and Delete buttons as the last two columns in the Gridview control. The following code works fine without any issues when I have the delete button only:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
if (e.Row.RowType != DataControlRowType.DataRow) return;
int lastCellIndex = e.Row.Cells.Count - 1;
Button db = (Button)e.Row.Cells[lastCellIndex].Controls[0];
db.OnClientClick = "if (!window.confirm('Are you sure you want to delete this record?')) return false;";

But, when I have both the Edit and the Delete buttons, I get the following error when I click the edit button while the delete button works fine.

Specified argument was out of the range of valid values. Parameter name: index

How do I reference the delete button so the edit button is not affected in this case?

Forms Data Controls :: Delete Images From Folder Using Gridview Delete Link?

Feb 3, 2010

Using "Enable Delete" from Gridview control, I can delete (besides, update, sort, paging, etc) data from the database (this is done automatically). However, how can I delete the actual image that resides in my image folder (i.e. from "pix" folder )? What is the best way to delete image? If using code behind, how? Please write a full code for me. Here is my source code.

Forms Data Controls :: Have A Grid Contol That Allows Delete What Would Like To Have Is Someway To Say Are You Sure You Want To Delete?

Feb 8, 2010

I have a grid contol that allows delete what I would like to have is someway to say Are you sure you want to delete?I found this code online, and tried it but it did not work, Do I need something more some behind code maybe?Here is what I found online:Adding 'Delete Protection' to controls If you use a control set up to allow Delete, the Delete button gives a straight delete without any warning, which can be dangerous.To give a warning dialog box, add an OnClientClick event to the Delete button, as follows.

runat="server" CausesValidation="False"
OnClientClick="return confirm('Are you sure you want to delete this record?');"

Here is my code: You can see where I added the code from above.

ID:<asp:label id="IDLabel" runat="server" Text='<%# Eval("ID") %>' /><br />
Name:<asp:label id="NameLabel" runat="server" Text='<%# Bind("Name") %>' /><br />
Destination:<asp:label id="DestinationLabel" runat="server" Text='<%# Bind("Destination") %>' /><br />
OutDate:<asp:label id="OutDateLabel" runat="server" Text='<%# Bind("OutDate") %>' /><br />
ReturnDate:<asp:label id="ReturnDateLabel" runat="server" Text='<%# Bind("ReturnDate") %>' /><br />
LeaveTime:<asp:label id="LeaveTimeLabel" runat="server" Text='<%# Bind("LeaveTime") %>' /><br />
ReturnTime:<asp:label id="ReturnTimeLabel" runat="server" Text='<%# Bind("ReturnTime") %>' /><br />
ContactNumber:<asp:label id="ContactNumberLabel" runat="server" Text='<%# Bind("ContactNumber") %>' />
<asp:linkbutton id="EditButton" runat="server" CausesValidation="False" CommandName="Edit" Text="Edit" />
<asp:linkbutton id="DeleteButton" runat="server" CausesValidation="False" CommandName="Delete" OnClientClick="return confirm('Are you sure you want to delete this record?');" Text="Delete" />
<asp:linkbutton id="NewButton" runat="server" CausesValidation="False" CommandName="New" Text="New" />

Feb 22, 2010

I need you assistance, Dynamic Delete LinkButton with CommandName=Delete gives me an error: Delete can only be called on a valid data item. nfact I am designing a Complex Grid using .Net 3.5 ListView Control with Scrollbar and Fixed Toolbar: This grid consist of 3 Tables:

1- footer

ImageButton with stop icon is with CommandName="Delete"

C# - Datagrid Getting Selected Value (delete Xml Node)?

Dec 26, 2010

Lets assume there are 2 columns in my datagrid:

<asp:View ID="viewRemove" runat="server">
<asp:DataGrid ID="dgRemove" runat="server" AutoGenerateColumns="False" OnDeleteCommand="dg_DeleteCommand">
<asp:BoundColumn DataField="name" HeaderText="names" />
<asp:ButtonColumn ButtonType="PushButton" Text="Delete" CommandName="Delete" ></asp:ButtonColumn>

The first column displays names from a xml file and the button column just hold delete buttons so i can delete the corresponding item to the left of it (1st column).

How exactly can i retrieve/pass this selected value to a function? In other words when i press the button to the right of the name, it passes the value so i can work with that to remove the corresponding xml node. (using XPath)

XmlDocument XMLDoc = new XmlDocument();
XPathNavigator nav = XMLDoc.CreateNavigator();
var node = nav.SelectSingleNode("/root/name['" + ??? + "']");
