When i checked checkbox and after click "detay"detailsbutton,i need to show me selectedrows details in popUp. I use devexpress aspx. How can i do guys please help me.
My Code
My Page
Refer: ASPxGridView - Get selected rows on the server side
Use the server-side ASPxGridView.GetSelectedFieldValues method to
retrieve selected values of the required column (a key column is the
ASPxGridView.KeyFieldName). Refer to the How to delete the
ASPxGridView's selected rows Code Central example that illustrates
how to use this method.

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 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 to alternate DataSource in ComboBox Column inside Devexpress GridView by selecting value in other ComboBox column in same row.
It is something like cascading comboboxes but in Grid view (but in grid comboboxses don't have CallbackRouteValues property)
Grid has two comboboxes and if user selects one value in frst the second combobox must change datasource by function that takes id as parameter from first selected combobox
You want to use a LookUpEdit instead of ComboBox when you are using a datasource, then you can use the QueryPopUp event to set a filter to, or change your datasource.
Note that when you change the datasource for the LookUpEdit, the result in the grid might not look what you expected. To remedy that, you want to clear your filter in the QueryCloseUp event.
I need list view, that supports column with check boxes. Please help me add column with check boxes to ListView or add paging to CheckboxList
EDIT: I've forgot that also I need data bounding.
I've found out IPagedItemContainer interface and DataPager class. I need to add interface implementation to CheckboxList.
For Listview I haven't found any ideas on adding column
Use GridView with unvisible Header Row. And add a Checkbox Column.
