I have a gridview with 100 Rows with paging turned on (showing 20 rows at a time).
There is a checkbox in each row to select that record.
In the header there is a "check all" checkbox
When I check it will just select the 20 from the current page.
Is there a way to have it select all 100 rows with out resizing the size of the page (have it show all 100 rows).
Thanks
Add a field checked in your datalist , and set its value according to the checked all checkbox.
You can have a property in that table which is bound to grid and you
can set this attribute when checkall is clicked and based on this
attribute the check box in each row can be rendered.
If you want to bind any functionality on all the rows in gridview, you can simply use dataview of the data source of the grid view on check all click. Or you can perform desired operation on the datasource(data table or dataset) on CheckAll checkbox checked

I have a Kendo UI MVC Grid where I'd like to add a special checkbox column.
This column will not be bound to a model but will be used like a sort of filter.
The idea is that users can check some rows and then click a button (for instance the filter icon in the column header). When clicked, the grid should collapse to the selected rows. The way I see it, it is an extra filter, but not the usual way.
The way my users will work with it would be about as follows:
They select a row and play the attached sound file for that row.
If the row holds an interesting sound file, they may check the checkbox and move to a new row -> 1.
After the selection with checkboxes is made, they will click on the checkbox column filter icon.
The selection will then collapse to the rows that were selected.
After this, the collapsed grid may be exported to excel, pdf or whatever…
A multi select grid is not an option as well as a checkboxed column filter because the selection is not instant, but a process over time.
I cannot find how I would make #4 work. Any suggestions? I don't need a complete solution, ideas are welcome.
The best way is to add boolean 'util' property to your model and bind it to a checkbox column. Once your checkbox column will be bound, your button can execute:
dataSource.filter({ field:"Field", operator: "eq", value: true });
As far I know - there is no build kendo way to manage filtering unbounded columns.
I have a datagridview and recently I got task to add a checkbox column (which I did) and a button (btnFilter) that will filter/show only selected rows so for example if I check only 4th, 5th and 6th row and click on 'btnFilter' the datagridview would show only rows 4,5 and 6.
So, the problem is how to show only selected (checkbox) rows.
Thank you for your time.
The idea is to have a button which when clicked, a loop will be executed over GridView Rows. Within the loop we will check whether the CheckBox for that row is checked, if the CheckBox is checked then the Value from the GridView Row Cell and Cell controls like Label, TextBox, DropDownList, etc. can be fetched.
Here is the complete example with screenshots and source code in C# and VB
GridView checkbox: Get Selected rows
So in this photo I have a gridview,
Column 1 is DropDownList, Column 2 is TextBox and Column 3 is Read Only. for Column 1 as a TextBox, when I clicked Edit, changed the value of TextBox and then I clicked Update, the Value of Column 1 chenged. Then I replaced TextBox from column 1 to a DropDownList. I converted Column1 into a TemplateField, Edited template field of column 1 and changed it as a DropDownList. Now When I try to Edit a Row, I choose another value from DropDownList and it doesn't change.
NOTE: I haven't don this programmatically. .aspx.cs file is empty. I have done this via GridView Tasks.
UPDATE:
I have managed to fix the problem.
On EditTemplateField, on DropDownList I clicked Edit Data Bindings
After that on Selected Value I bounded it to the column I want.
I am working on a master/detail gridview and detailsview in asp.net web forms using an objectdatasource. The details view is displaying extra information about the selected row from the gridview. When I sort the grid, I want the currently selected row, before sort occurs, to remain in the details view after the sort is completed. Instead, the gridview is auto selecting the new first row whenever I sort.
I found a partial solution to this problem. If I set WhateverGridview.SelectedIndex= -1 onsort and the value becomes null. This makes it deselect any rows after a sort. This leaves the details view blank. However, what I want to do is maintain the selected row not nullify it.
So, does anyone have a good way to retain the selected value or prevent the details view from displaying after sort event fires.
Here you need to use the GridView.EnablePersistedSelection property. Set this property to true.
Setting this property to true means that GridView will make sure that the selection of a row is based on data-key values.
By default GridView makes row selections based on index. This is the reason why when you sort, gridview is selecting row based on index and you lose your actual selected row.
How can I Display selected row of Gridview data to next page in another Gridview?
For example,
In listing page I want to select particular row and take that data to another page and display over there.
I have two grid view one in 1st page
and next one in 2nd page. Now when I
select a record in 1st page gridview,
than that record will display on 2nd
page gridview on submit button click
from 1st page.
Pass the key of the record via the querystring... and then in rowdatabound event, select the row when the data bound record matches the key in the QS.
For more protection, you can use session to store the variable.
Why not have 2 gridviews, one above the other? The top gridview could be made to only show 1 record which is set to the id of the 2nd gridviews selected item identifier in code. Then in 2nd gridview, have an empty selected item template so that the selected item only shows once for both gridviews. That way the 2nd gridview is free to page through the entire set whilst the first retains the selected item for display above?
