Forms Data Controls :: Show Checked Checkboxes In Gridview From Database

Mar 4, 2010

I have situation where I have to show checked CheckBox in a GridView. I have three tables

1) Menu Items ( Fields: menuID, menuName, menuLink, .....)
2) User Types (Fields: userTypeID, userTypeName, ...)
3) User Menus (Field: menuID, userTypeID )

I have a screen to add new Menu Items where I am showing a Grid That has two columns

1) CheckBox and
2) User Type

I have to check CheckBox in order to Link that User Type with the Menu Itme. I am done with Add Screen. Here is the Code:

(aspx)
<asp:GridView
ID="gridView_UserTypes"
runat="server"
AutoGenerateColumns="False"
DataKeyNames="userTypeID"
Width="60%"
EmptyDataText="">
<HeaderStyle
CssClass="gridHeader"
Wrap="false"
/>
<AlternatingRowStyle
CssClass="gridAlturnateRow"
/>
<RowStyle
CssClass="gridRow"
/>
<Columns>
<asp:CheckBoxField
DataField="userTypeChecked"
HeaderText="Select"
ReadOnly="false"
Visible="true"
/>
<asp:TemplateField
HeaderText="Select">
<ItemTemplate>
<asp:CheckBox
ID="userTypeSelector"
runat="server"
/>
</ItemTemplate>
<ItemStyle
HorizontalAlign="Center"></ItemStyle>
</asp:TemplateField>
<asp:BoundField
ItemStyle-HorizontalAlign="Left"
DataField="userTypeName"
HeaderText="User Types"
HeaderStyle-Wrap="false"
ReadOnly="True"
SortExpression="userTypeID">
<ItemStyle
HorizontalAlign="Left"></ItemStyle>
</asp:BoundField>
</Columns>
</asp:GridView>
(Code Behind)
foreach (GridViewRow row in gridView_UserTypes.Rows)
{
// Access the CheckBox
CheckBox cb = (CheckBox)row.FindControl("userTypeSelector");
if (cb != null && cb.Checked)
{
// First, get the UserTypeID for the selected row
int userTypeID = Convert.ToInt32(gridView_UserTypes.DataKeys[row.RowIndex].Value);
if (selectedUserTypeIDs == "")
{
selectedUserTypeIDs = userTypeID.ToString();
}
else
{
selectedUserTypeIDs = selectedUserTypeIDs + "," + userTypeID.ToString();
}
userTypeCount++;
}
}

Now I am passing selectedUserTypeIDs along with other details to my Stored Procedure and adding those UserTypes for newly Added menu. It works fine for me. Now I want to show checked CheckBox in Edit Mode.

Forms Data Controls :: Checkboxes In Datagrid / Update A Label In The Page With A Value Associated With The Row Of The Checked Checkbox

Aug 26, 2010

This morning I posted a question w.r.t Radio Buttons, but the requirement changed so I'm posing a similar question.

I want to have a checkbox in a datagrid.

Suppose I click on one of the checkboxes and then realize i need to click on another, the screen has to automatically uncheck the previously clicked checkbox and then check the newly clicked checkbox.

In other words I need to clear previously checked checkboxes and check the recently clicked checkbox.

Also, I need to update a label in the page with a value associated with the row of the checked checkbox.

I should not be using a javascript to do this.

Forms Data Controls :: Get "checked" From Multiple Dynamically Generated Checkboxes?

Nov 16, 2010

I have a table witch i programmatically fill with(multiple) IDs in the first column, options in the second and checkboxes in the third. The table is in a View as it is part of a wizard and is filled on view_Activate.

How can i get the checked property of the checkboxes when i pass to the next view? When i try to do that on view_Deactivate the table is already 0 rows...

I know i can use i checkboxlist(... whose properties i can get on view_Deactivate) but i'd rather use a table as it is easier to layout as i want it(header, columns, alignment,...).

Web Forms :: How To Determine If All Checkboxes Are Checked In Code Behind

Feb 17, 2011

I have a page that im using javascript to do a select all / unselect all for my checkboxes on the page. Now i need to determine in the code behind if all of them are checked, im wondering if it would be easier to just set a session or something whenthe select all is checked, but that wouldnt be accurate, because after you select all, you still can uncheck some..

So i need it to check at the time the button is clicked.. there are currectly 30 checkboxes, NOT a checkboxlist.

I tried using the site search but getting an error has occured when i click to search..

TreeView Nodes Always Have Checked = True On Postback Even When Not Checked In UI

Mar 15, 2010

I have a treeview in my .aspx: <asp:TreeView ID="tvDocCatAndType" runat="server" /> Not much else going on in the page -- two <asp:LinkButtons> and one <asp:Label>; the page is a child of a master page, so these controls are within a <asp:Content> control. I populate the treeview in code -- just 3 node levels, including the root node. All nodes have checkboxes, and I initialize all node.Checked to true. I have some Javascript to do the usual check/uncheck up and down the tree as parent and child node checkboxes are toggled.

No matter how many checkboxes I clear in the UI, on postback every single node has node.Checked = true regardless of the state of the checkbox in the UI. This is not the first time I've used a treeview, but I've never had this problem before. I created this page by light adaptation of an earlier project that works fine.

JavaScript - Check If A Checkbox Is Checked In A Group Of Checkboxes In Clientside?

Apr 3, 2011

note that the scenario is ASP.NET Webforms + Master - Content page which mess up the ids.

I have, say, three checkboxes

<asp:CheckBox ID="chkConsultantQuality" runat="server"
CssClass="company"/>
<asp:CheckBox ID="chkConsultantEnvironment" runat="server"
CssClass="company"/>
<asp:CheckBox ID="chkConsultantSafety" runat="server"
CssClass="company"/>

I would like to make a div id="CompanyPanel" on click event of each checkbox according to the following condition

visible if any of the checkboxes are checked.

hidden if all of the checkboxes are unchecked.

I am planning to use jQuery since I am selecting by class name. I could do it with jQuery.each on the class='company' by checking each for a checked flag.
