Getting ID Of A Control From Gridview Edit Mode To Be Used By Javascript?
Jun 8, 2011Basically what needs to happen is when the user clicks edit onto the gridview and clicks on a certain textbox a javascript calendar popups up and the user picks a date.So far, I can set it statically and the calendar works for that one row, but not the other rows since the ID changes.My ASP Code (id of textbox has been set to txtStartDate):
<asp:TemplateField SortExpression="StartDate" HeaderText="Start Date">
<EditItemTemplate>
<asp:TextBox ID="txtStartDate" onClick="ddlchange()" Runat="server" Text='<%#Bind("StartDate")%>'>

This works, for one textbox. It does not work for other since 'ct102' changes with every row.
Populate GridView Control From A Linq To SQL DataSource?
Jul 22, 2009If I used a generic list Class to hold data objects that I am pulling from SQL Server using Linq to sql to populate a datagridview would I need to make any modifications to the datagridview control to accomodate multiple columns or would I need to make any modifications to the generic list class to accomodate the multiple columns in a row that is typical of a record in SQL Server? And one more thing which I believe is the easy part. To bind the list to a datagrid view would I just use the datasource property of the datagridview control.

May 3, 2012I have a GRIDVIEW with columns, one of which contains a CSV of possible values for the dropdown that must appear on each row.

If e.Row.RowType = DataControlRowType.DataRow Then[code].....
Depending on whether the type of control is a dropdown, textbox, or check box (feined in the table) it hides or shows the relevant control type. If it is a dropdown it needs to get its values from a CSV in a corresponding column. I have a SP that returns a these in table form if passed the id of the relevant row.How do I get that is from the gridview to pass to the drop down and load it correctly?
Asp.net - FileUpload Control Inside Gridview (ajax Updatepanel)?
Mar 11, 2011I've got a fileupload control inside of a gridview so that each row (item from the database) can have an attachment associated with it. I've got a button next to the fileupload control (besides the default browse... button to select the file) to actually take the file and upload it to a file server.This works great if I use this button "Upload". However, underneath my gridview I have another imagebutton that is outside of the gridview, its just sitting on the form / page.The idea of this "Update" button is when end users make changes to the grid I can simply loop through the grid and update the values they have entered to the database. This also works great.
Now here is my issue assume a user has 3 rows in the grid view. On 2 of these rows he decides to add an attachment but he never clicks the "Upload" button he only uses the standard browse button to select the file. Now instead of clicking the "Upload" button that is on the grid view he ends up clicking the "Update" button outside of the grid thinking that it will save his attachments.
So I decided to write code to grab the fileupload control from the grid using .FindControls("NameOfFileUploadControl") in my Update button loop where I loop through all the rows. Then I check if myFileUploadControl.HasFile property to see if there exists a file and if there does upload the file then continue with the code.
The issue is when I click this "Update" button .HasFile always returns false even though I can see the text string of the path in the fileuploadcontrol textbox (the standard one next to the browse button). Is it because this goes back to the page load event and checks if it is a post back? What causes this and how can I fix it?
edit:Im adding some code because im still confused with this
Protected Sub SaveGrid()
For Each Row As GridViewRow In Me.gvLineItems.Rows
Dim f As FileUpload = CType(Row.FindControl("fuAttachment"), FileUpload)
[code]....
This method gets called on a click of a button... The fileupload control is in an of a gridview that is wrapped inside of an UpdatePanel:
<asp:FileUpload Width="90px" Font-Size="xx-small" ID="fuAttachment" runat="server" />
So why is this property always returning false?
Changing Database Tables Displayed In A GridView Control?
Sep 17, 2010Using a Windows Form with a Menu bar and a Gridview control, I have bound data to the GridView from an MS Access 2000 database query using Dataset. The contents of this table displays just fine. But I want to be able for the user to select a different query from the menu bar and display it in the same GridView control. How can I change the query bound to the control (in VB)?
Public Class Actinide Private Sub Minerals_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.Actinide_Series__Radioactive_TableAdapter.Fill(Me.Minerals2000DataSet._Actinide_Series__Radioactive_) End Sub Private Sub LanthanideToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LanthanideToolStri
[code]....
The error message that it is giving me is:
"Value of type 'Mineralogy.Minerals2000DataSet.Yttrium_MineralsDa ta Table cannot be converted to
'Mineralogy.Minerals2000DataSet._Actinide_Series__ Radioactive_Data Table'.
The query is getting information from two seperate tables,so I can't just bind a table to the control and then filter what is displayed using SQL.
