I have an GridView with DB informations. In my aspx, I have 2 checkbox. I need make check in one checkbox for each row according to AccessType value. How I can capture AccessType value in foreach?
My aspx (GridView)
<asp:GridView ID="GridView" runat="server" AutoGenerateColumns="false" GridLines="None">
<Columns>
<asp:BoundField DataField="AccessGroup" HeaderText="Access Group" />
<asp:BoundField DataField="FolderAccess" HeaderText="Folder Access" />
<asp:HyperLinkField DataNavigateUrlFields="group_manager" DataNavigateUrlFormatString="groupinfo.aspx?group={0}"
DataTextField="group_manager" HeaderText="Group Manager" />
<asp:BoundField DataField="AccessType" Visible="false" />
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="CheckBox1" runat="server" Text="Access to Read" />
<asp:CheckBox ID="CheckBox2" runat="server" Text="Access to Modify" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
My .cs
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
var listaProdutos = new RequestAccess().ConsultarProdutos();
if (listaProdutos != null)
{
this.GridView.DataSource = listaProdutos;
this.GridView.DataBind();
foreach (GridViewRow row in GridView.Rows)
{
CheckBox check = (CheckBox)row.FindControl("CheckBox1");
CheckBox check2 = (CheckBox)row.FindControl("CheckBox2");
//EX!!!
//IF AccessType = 1
//{
// check.Checked = true;
//}
//IF AccessType = 2
//{
// check2.Checked = true;
//}
}
}
}
}
You can access BoundFields
via e.Row.Cells[index].Text
:
foreach (GridViewRow row in GridView.Rows)
{
string accessType = row.Cells[3].Text;
}
However, I would use RowDataBound
instead of an additional foreach
.
Here is the RowDataBound
event which is raised for every row in the GridView
when it was databound. Assuming the DataSource
is something like a DataTable
:
protected void GridView_RowDataBound(Object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
CheckBox check = (CheckBox)e.Row.FindControl("CheckBox1");
CheckBox check2 = (CheckBox)e.Row.FindControl("CheckBox2");
DataRow row = ((DataRowView)e.Row.DataItem).Row;
int accesType = row.Field<int>("AccessType");
check.Checked = accesType == 1;
check2.Checked = accesType == 2;
}
}
You could add the AccessType value to a HiddenField within the grid:
<asp:GridView ID="GridView" runat="server" AutoGenerateColumns="false"
onrowdatabound="GridView_RowDataBound">
<Columns>
<asp:BoundField DataField="AccessGroup" HeaderText="Access Group" />
<asp:BoundField DataField="FolderAccess" HeaderText="Folder Access" />
<asp:HyperLinkField DataNavigateUrlFields="group_manager" DataNavigateUrlFormatString="groupinfo.aspx?group={0}"
DataTextField="group_manager" HeaderText="Group Manager" />
<asp:BoundField DataField="AccessType" Visible="false" />
<asp:TemplateField>
<ItemTemplate>
<asp:HiddenField ID="hdnAccessType" runat="server" Value='<%# Eval("AccessType") %>' />
<asp:CheckBox ID="chkReadOnly" runat="server" Enabled="false" />
<asp:CheckBox ID="chkModify" runat="server" Enabled="false" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
and then use the RowDataBound event handler to get the AccessType value from the HiddenField control and set the checkbox accordingly:
protected void GridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
HiddenField hdnAccessType = (HiddenField)e.Row.FindControl("hdnAccessType");
int accessType = int.Parse(hdnAccessType.Value.ToString());
CheckBox chkReadOnly = (CheckBox)e.Row.FindControl("chkReadOnly");
CheckBox chkModify = (CheckBox)e.Row.FindControl("chkModify");
switch (accessType)
{
case 1:
chkReadOnly.Checked = true;
break;
case 2:
chkModify.Checked = true;
break;
}
}
}
