DataGrid Interview Questions

Using cache you can automatically refresh the datagrid data

Bind the datagrid by calling "datagridname.databind() "

DataGrid is the implementation of framework 1.1. It doesn't provide support for complex implementation such as image loading, combobox use in the datagrid control.

DataGridView is the implementation of framework 2.0 onwards. It is the overcome of 1.1 drawback.

1. In datagrid you have to do lots of task for sorting, paging. In gridview sorting, paging is much easier and you can do with only 2-3 line of coding.

2. DataGrid control doesn't take full advantage of data source components. GridView fully support data source components.

At design time, we can add button in footer template of the grid. <asp:TemplateField> .... <FooterTemplate> <asp:Label ID="lblTotalInvoiceAmount" runat="server" Text...

As they ask you to do it at run time, you need to add the controls to the control collection of the cell of the footer row of the gridView.
Button myBtn = new Button();

gvTest.FooterRow.Cells[1].Controls.Add(myBtn);

Play caution where the dynamic addition is done if you want it to persist.

Take template column and and Insert the Controls what ever you want to add the dataGrid, and find those control in Grid Itembound/ItemCommand.

If you want to add the controls on the grid, you can use item template.

Example:

<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="Chk" runat="server" />
</ItemTemplate>
</asp:TemplateField>

Yes, you can add rows one by one at runtime. for that you have to maintain DataTable and its ViewState. So after pageload data is not removed from datatable.For display purpose you have to bind that ...

Example
dim da as new sqldataadapter("select...",conn)
dim ds as new dataset
da.fill(ds,xyz)
dim dr as datarow
dr=ds.tables(0).rows.newrow
with dr
.items(0)=textbox1.text
.items(1)=textbox2.text
.items(2)=textbox3.text
ds.tables(0).addrow(dr)

datagrid1.datasource=ds.tables(0)
