Check All with JQuery and a Asp.Net GridView

Display a Grid on the screen with a checkbox in each row. At the bottom of the page have "Check All" button.

Typically if I need to do anything interesting I use a template column. So my GridView will look like the one below (most other columns removed for readability). The only interesting point to note is the CssClass="ApprovalCheckBox" in the CheckBox ItemTemplate.

Dynamically creating Gridview Template - Linkbutton Click not working



I have written some code to dynamically generate template columns for gridview which works well. However, each cell in the gridview has to be a linkbutton, which when clicked does a db update and redirects to a specific url with some parameters in it.

I have attached a click event handler to the linkbutton in the InstantiateIn method but the event does not seem to fire.

Could someone please help? the code is below -

Check In / Check Out not working properly

At various points during the day, I check back in the master and CSS files I've been working on.  However, it doesn't show them as checked in ... they are still flagged with green check in SP Designer.   And what is more confusing, sometimes I can't save anything because it says that it is checked out.  But I'm the one who checked it out.  And it thinks it is checked in.  So I try to check it out again, and it won't let me check it out. The only way I got around this yesterday was to rename the master file.  Then rename it back to it's original name. Suggestions?

How to disable fields in a GridView when you change the listbox options?

 Hi all I am trying to apply the same logic I applied to a FormView. Here is what I do:I have a DropDownListBox as one of my FormView fields and when I choose a specific option the fields inside my FormView are enabled/disabled according to the options chosen. Well I havent been able to apply that concept to a GridView. Here is my code to the FormView:protected void ItemFormView_DataBound(object sender, EventArgs e) { DropDownList ddlConfigType = ItemFormView.FindControl("ddlConfigTypes") as DropDownList; if (ddlConfigType != null) { if (ItemFormView.CurrentMode == FormViewMode.Edit) { DisableNAFields_EditMode(ddlConfigType.SelectedItem.Text); } } }private void DisableNAFields_EditMode(string configType) { TextBox txtboxScope = ItemFormView.FindControl("txtboxScope") as TextBox; if (configType == "registry") { txtboxScope.Enabled = false; } } Is there a GridView mode enumeration? How do I achieve the same goal? Thank you

Attempting to use an HTTP handler to display pictures in gridview. It's not working, please help.

I am writing a web page that needs pictures displayed for each item.  The page works just fine except for the pictures.  I have a file called handler.ashx uploaded to the server as well.  It does not seem to be hurting anything, but it doesn't seem to help display the pictures either!  I am working with a MySQL database so I am thinking that the call for the data or the ashx page's structure itself are my problem.  I am using C# Express so there is no generic handler class to autoload and therefore my handler page is pasted together and I know the using statements are in the wrong place, but I'm new to this and I'm lost!  The following is my database table info (table is named: Yamaha), my handler.ashx page code, and the code for the final web page.  I have loaded ".jpeg" or "jpeg" into the field I added called "Image_Type"  since I have already uploaded all pictures as longblobs.  You can view the final web page here: http://www.88867honda.com/YamahaPtsSale.aspx Thanks in advance for any help, Melissa   Table info: Field TypeAttributes--> Null DefaultExtra--> Comments part_number varchar(15)  --> No     -->   description varchar(50)  --> Yes  NULL   -->   qty int(4)  --> Yes  NULL

disable autopostback of checkbox inside of GridView during SelectedIndexChanged of ListView

Hi, I hope my question is clear: I have a checkbox placed inside a gridview: <GridView><asp:TemplateField HeaderText="Driver">   <ItemTemplate>       <asp:CheckBox ID="CheckBoxDriver" AutoPostBack="true" OnCheckedChanged="GridView_Persons_SelectedIndexChanged" ValidationGroup='<%# Eval("ID") + "-" +((GridViewRow)Container).RowIndex %>' CssClass="CXDriver" runat="server" Checked='false' />   </ItemTemplate>       </GridView> For example: A listViewItem 1 has 3 drivers are checked, A listViewItem 2 has 2 drivers are checked. Therefore, if changing the selectedIndex of the list, the checkbox indexChanged event will be fired. How could I disable the autopostback of the checkbox during the listview item changed. Thanks in advance

gridview checkbox sorting not working

Hi All,I have a grid view which populates data just for viewing purpose(report) . One field shows the Active/inactive status for which I am showing a checkbox..if data in database is 1 then the checkbox will be checked otherwise it'll not be checked. This field is inactive so that the User does not check/uncheck it. The issue is that this field cannot be sorted. All the fields in the gridview are being sorted. Below is the code for the checkbox column. <asp:TemplateField HeaderText="InActive" SortExpression="Inactive"><HeaderTemplate ><asp:Label ID="lblStat" CssClass="copyLabel" Text="Inactive" CommandArgument="Inactive"                    runat="server"></asp:Label></HeaderTemplate> <ItemTemplate><asp:CheckBox runat="server" ID="chkStatus" Enabled="false"/></ItemTemplate></asp:TemplateField>I have given AllowSorting="True" in the gridview properties. The code in the gridview sorting event works fine for all other columns except the checkbox column. Please help and suggest some scenarios/links so that I can achieve sorting for the checkbox column also.Thanks in advance.

Gridview Delete not working

I just downloaded VS2010 with Framework 4.0.30319 I've bound a gridview control to a datasource, defined the select, insert, and delete SQL statements. Select and insert are working just fine thank you, but when I select the (auto-generated) Delete link, a postback occurs, but the row/record remains in the gridview. I have the one-segment key in the select statement, in an invisible column of the gidview. I've set the DataKeyNames property to this column name (CinID).  The delete query reads - DELETE FROM CallIn WHERE (CinID = Cid) I've defined the parameter Cid as the Gridview.SelectedRow, .SelectedDataKey, .SelectedIndex, and .SelectedValue, all with no joy. I created SUB Gridview.RowCommand put a breakpoint there. e.Command shows "Delete" and e.CommandArgument shows the correct row index (1). I created SUB Girdview.DeletingRow and put a breakpoint there. debug shows .SelectedRow=nothing and .SelectedDataKey=nothing (but I don't know if they *should* show something, since I'm not selecting, but rather deleting the row. The postback occurs (click), the grid refreshes, but nothing happens. I cannot figure out why the clicked-on row does not delete. Any ideas?
