I have a gridview where in textbox should be editable in few cases only.. i have tried the following code but its not working how to resolve this and make textbox non editable..
protected void GridView1_OnRowEditing(object sender, GridViewEditEventArgs e)
{
....
if (some condition)
{
..................
}
else(some condition)
{
.............
}
else if(some other)
{
TextBox itm = (GVEditRate.Rows[e.NewEditIndex].FindControl("TextBox1") as TextBox);
itm.Enabled = true;
TextBox prfc = (GVEditRate.Rows[e.NewEditIndex].FindControl("TextBox2") as TextBox);
prfc.Enabled = false;
TextBox anest = (GVEditRate.Rows[e.NewEditIndex].FindControl("TextBox3") as TextBox);
anest.Enabled = false;
}
Have you tried This:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowState == DataControlRowState.Edit || e.Row.RowState == DataControlRowState.Alternate)
{
//on you condition
TextBox txt = (TextBox)e.Row.FindControl("ControlID");
if(txt !=null)
{
txt.Attributes.Add("readonly", "readonly");
// txt.Attributes.Remove("readonly"); To remove readonly attribute
}
}
}
As it is in comment you can do the following code on RowDataBound Event
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowState == DataControlRowState.Edit || e.Row.RowState == DataControlRowState.Alternate)
{
//on you condition
TextBox txt = (TextBox)e.Row.FindControl("ControlID");
txt.ReadOnly = true;
}
}
I prefer use Data-Binding Expressions in the page in the column of the grid
<asp:TextBox runat="server" Enabled='<%# YourMethodThatReturnCondition(Eval("Field1"), Eval("Field2"), ...)%>' ></asp:TextBox>
Wehre YourMethodThatReturnCondition is a method that return a boolean
<asp:GridView ID="grdTaskDataCat1" OnRowCommand="grdTaskDataCat1_RowCommand" OnSorting="grdTaskDataCat1_Sorting" AutoGenerateColumns="false" ShowHeaderWhenEmpty="true" AllowSorting="true" Width="100%" DataKeyNames="ID" runat="server" OnRowDataBound="grdTaskDataCat1_RowDataBound">
<Columns> <asp:TemplateField HeaderText="Sr No" Visible="false"> <ItemTemplate> <asp:TextBox ID="txtId" Visible="false" ReadOnly Style="width: 30%" Text='<%# Bind("ID")%>' runat="server"></asp:TextBox> </ItemTemplate> </asp:TemplateField>
</Columns>
</asp:GridView>
On ROW data bound of the gridview
protected void grdTaskDataCat1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
TextBox txt = (TextBox)e.Row.FindControl("txtTaskName");
if (txt.Text != "")
{
txt.Attributes.Add("readonly", "readonly");
}
}
}
