Forms Data Controls :: How To Add A Master Checkbox To The Header Of A Gridview
Aug 1, 2010
I have a gridview which includes a column of checkboxes down the left side, inserted using <asp:TemplateField>. Currently I can check / uncheck the checkboxes against particular records, to select the records I want to apply changes to.
My question is, how can I add a "master" checkbox into the gridview header, to toggle all of the checkboxes together? I would like to be able to use this to check / un-check all the checkboxes together.
I want to select all checkBox in Gridview when click to header checkBox.I have created design such that CheckBox is not available to header of Gridview.It is in other table. Below is design of gridview.
I have creted a checkbox for each column of grid at the top of the header in row created event. I need to check wheather checkbox is checked after button click event.
Scenario: I have a Gridview where I want to handle the Sorting in a custom control that I've added to the header. I've added this control to my GridView's Header via OnRowCreate event handling. I want the Sort Expressions to persist session to session (via Webparts Personalization)
Here is what I have for adding the custom header control to the GridView Header
[Code]....
This works out well for adding the control, but I can't get anything to persist because these controls are creating initially via postback (per the event) and re-created on all subsequent postbacks. I can't add an If(!IsPostback) because the controls are initially created on the gridview's postback (well at least thats how it's acting when I put it in there) If I were to add this control via the ASP page, not via the Codebehind, I would be able to persist the control. If I try to treat it as though everything is setup correctly, and assign my custom control's controls to [Personalizable], I get a runtime error telling me that I can only have webpartzones in or before Page_init (I'm guessing this is due to when/where the gridview hits the OnRowCreate event). If there is some fundimental logic I'm missing, or best practices that I'm moving away from,
I try to add a header checkbox to selecte all in the column, I know that with templeate field you can but the problem is that i don't know the number of columns. How i add a checkbox to the header in every column?
I want to raise an checkbox check-changed event but its not firing :( . It Dosent raise even an command event.
My Requirement :
My Requirement is that i have a Datalist with header checkbox in headertemplate and a child checkbox in itemtemplate and a gridview control. Checking and unchecking will update the gridview control.
i have a gridview bound to sql datasource with template fields binding the columns. I have set the Header Style to a css class. I have 3 columns not bound to data as Add, Edit and Delete. When I set the text color to white for the header only the non bound columns go white. The bound columns are BLUE like hyperlink. Any one know a way round this. (If I set the style in the gridview the all columns are white. Want to set in external css file).
I wnat to have checkbox in Gridview Header. On the checkbox changed I wnat to check and uncheck all the checkboxes of the Gridview Rows. Currently I am doing it on the button click. But I want to have checkbox in Gridview header, How to have checkbox in Gridview Header,can somebody tell me??
I edited my gridview template by adding an additional column of checkbox and to its header
I managed to do a checkchange for select all or none and for selecting single of multiple checkbox.
My problem here is that when I try to select all, uncheck another checkbox, the header checkbox is still checked and the unchecked checkbox becomes checked again.
If i did not check my header checkbox and just check it normally, its fine.
I have a GridView that I was previously populating via an ObjectDataSource, and this code was working perfectly (ie, when the checkbox was checked Checkbox.Checked = true):
now the problem is that when i scroll down the gridview the header disappers and so I could not remember what a number is refering to...how can I fix the header so that I scroll down only the rows? is too much if I ask you for the code and where to put it? :P it is a home project for myself so I m not going to sell it or earn money form it.
I have a gridview with the following header shown below
TYPE LOCATION
Big New York
Small BOSTON
Now, I would like to add a background colour for the headers TYPE, LOCATION. How do you do that? Kindly note, I am not trying to add a text color but instead a background color
I have this problem. The header row is showed when I want to make GridView and do not use AutoGenerateColumns. In the case I set ShowHeader="true" I can see:
<tr><th scope="col"></th></tr> at HTML code, but if I set ShowHeader to false I see this:
<tr><th></th></tr>. I don't know why the header row don't disappear.
