I have a GridView that has 10 columns populated by CheckBoxes. But instead of using FindControl()
is there a way to get the CheckBox.Checked
value by using a loop?
Current Code:
if (e.CommandName == "updaterow")
{
int index = Convert.ToInt32(e.CommandArgument);
GridViewRow selectedRow = GridView1.Rows[index];
// TableCell BranchCode = selectedRow.Cells[0];
CheckBox cb101 = (CheckBox)selectedRow.FindControl("cb101");
CheckBox cb102 = (CheckBox)selectedRow.FindControl("cb102");
//...and so on
}
ASPX CODE:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" OnRowCommand="GridView1_RowCommand">
<Columns>
<asp:TemplateField HeaderText="101">
<ItemTemplate>
<asp:CheckBox runat="server" id="cb101" AutoPostBack="false" Checked='<%# Eval("101").ToString()=="1" ? true : false %>' Enabled='<%#(String.IsNullOrEmpty(Eval("101").ToString()) ? false: true) %>'/>
</ItemTemplate>
</asp:TemplateField>
....and so on
<asp:ButtonField ButtonType="Button" CommandName="updaterow" Text="Update"/>
</Columns>
</asp:GridView>

Try this,
Using foreach
Loop:
foreach (GridViewRow row in GridView1.Rows)
{
CheckBox chk = row.Cells[0].Controls[0] as CheckBox;
if (chk != null && chk.Checked)
{
// ...
}
}
Use it in OnRowCommand
event and get checked CheckBox value.
GridViewRow row = (GridViewRow)(((Control)e.CommandSource).NamingContainer);
int requisitionId = Convert.ToInt32(e.CommandArgument);
CheckBox cbox = (CheckBox)row.Cells[3].Controls[0];
foreach (GridViewRow row in GridView1.Rows)
{
CheckBox chkbox = (CheckBox)row.FindControl("CheckBox1");
if (chkbox.Checked == true)
{
// Your Code
}
}
foreach (DataRow row in DataRow row in GridView1.Rows)
{
foreach (DataColumn c in GridView1.Columns)
bool ckbVal = (bool)(row[c.ColumnName]);
}
Blockquote
foreach (GridViewRow row in tempGrid.Rows)
{
dt.Rows.Add();
for (int i = 0; i < row.Controls.Count; i++)
{
Control control = row.Controls[i];
if (control.Controls.Count==1)
{
CheckBox chk = row.Cells[i].Controls[0] as CheckBox;
if (chk != null && chk.Checked)
{
dt.Rows[dt.Rows.Count - 1][i] = "True";
}
else
dt.Rows[dt.Rows.Count - 1][i] = "False";
}
else
dt.Rows[dt.Rows.Count - 1][i] = row.Cells[i].Text.Replace(" ", "");
}
}
For run all lines of GridView don't use for
loop, use foreach
loop like:
foreach (GridViewRow row in yourGridName.Rows) //Running all lines of grid
{
if (row.RowType == DataControlRowType.DataRow)
{
CheckBox chkRow = (row.Cells[0].FindControl("chkRow") as CheckBox);
if (chkRow.Checked)
{
//if checked do something
}
}
}
If you want a method other than findcontrol try the following:
GridViewRow row = Gridview1.SelectedRow;
int CustomerId = int.parse(row.Cells[0].Text);// to get the column value
CheckBox checkbox1= row.Cells[0].Controls[0] as CheckBox; // you can access the controls like this
You want an independent for loop for all the rows in grid view, then refer the below link
http://nikhilsreeni.wordpress.com/asp-net/checkbox/
Select all checkbox in Gridview
CheckBox cb = default(CheckBox);
for (int i = 0; i <= grdforumcomments.Rows.Count – 1; i++)
{
cb = (CheckBox)grdforumcomments.Rows[i].Cells[0].FindControl(“cbSel”);
cb.Checked = ((CheckBox)sender).Checked;
}
Select checked rows to a dataset; For gridview multiple edit
CheckBox cb = default(CheckBox);
foreach (GridViewRow row in grdforumcomments.Rows)
{
cb = (CheckBox)row.FindControl("cbsel");
if (cb.Checked)
{
drArticleCommentsUpdates = dtArticleCommentsUpdates.NewRow();
drArticleCommentsUpdates["Id"] = dgItem.Cells[0].Text;
drArticleCommentsUpdates["Date"] = System.DateTime.Now;dtArticleCommentsUpdates.Rows.Add(drArticleCommentsUpdates);
}
}
