I have a problem which in theory should be very simple but i spent 3 hours now not being able to figure it out. I have a gridview and lingdatasource and i try to implement custom paging. No matter what i do i seem to be stuck with a pagesize of 25! Code below
Thanks!
aspx page
<asp:GridView ID="gvCustomerList" SkinID="StandardGridView" AutoGenerateColumns="false" DataSourceID="LqCustomerSource"
AllowPaging="false" AllowSorting="false" PageSize="50" runat="server" OnSorting="gvCustomerList_OnSorting"

</Columns>
</asp:GridView>
</div>
<asp:LinqDataSource ID="LqCustomerSource" AutoPage="false" runat="server"
OnSelecting="LqCustomerSource_Selecting" AutoSort="False">
</asp:LinqDataSource>
code behind
protected void LqCustomerSource_Selecting(object sender, LinqDataSourceSelectEventArgs e)
{
try
{
CustomerDataManager manager = new CustomerDataManager();
string searchName = "";// txtCustomerName.Text.Trim();
int count = 0;
List<Customer> customerList = manager.GetSelectedCustomers(gvCustomerList.PageIndex * 50, 50, searchName, SortExpression, SortDirectionForCustomers, out count);
//List<CustomerInsuranceInfo> infoList = manager.GetCustomerInsuranceDataFromList(customerList);
lblRows.Text = count.ToString();
e.Arguments.StartRowIndex = 0;
e.Arguments.MaximumRows = 50;
e.Arguments.TotalRowCount = count;
if (customerList == null)
e.Cancel = true;
else
e.Result = customerList;
}
catch (Exception ex)
{
ApplicationLogBO.Log(ex);
// Alert(WebsiteUtil.StandardErrorMessage);
e.Cancel = true;
}
}
Ok, it looks like you need to set it in the code behind in LqCustomerSource_Selecting
gvCustomerList.PageSize = 50

I have a problem for retrieving values for deleting records.
I'm using OnRowDeleting in a gridview with templatefields, and I can't retrive record selected value for deleting, this is my grid:
<asp:GridView ID="gvw_Cli_Emp_EmpData" runat="server" AutoGenerateColumns="false"
CssClass="mGrid" PagerStyle-CssClass="pgr" Width="50%" AutoGenerateDeleteButton="True"

</asp:TemplateField>
<asp:TemplateField HeaderText="CLIENTE">

<asp:Label ID="lbl_CliEmp_EmpNiv" runat="server" Text='<%# Eval("NivelAcceso1") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
And for delete:
protected void Borrando(object sender, GridViewDeleteEventArgs e)
{
string cell = gvw_Cli_Emp_EmpData.Rows[e.RowIndex].Cells[0].Text; //this retuns me ""
int EmpCliCod = Convert.ToInt32(cell);
DialogResult dialogResult = MessageBox.Show(new Form { TopMost = true }, "Delete?", "Confirma", MessageBoxButtons.YesNo);
if (dialogResult == DialogResult.Yes)
{
cliEmpBL.clientesEmpleados_SupEmpleado(EmpCliCod); //here execute deletion record from my datalayer
Page.ClientScript.RegisterStartupScript(this.GetType(), "AlertScript", "alert('Deleted!');", true);
}
else if (dialogResult == DialogResult.No)
{ }
}
So, as you can see returns me "".
I have tried resolve this, using:
System.Windows.Forms.Label EmpId = e.Item.FindControl("lbl_CliEmp_CliCod") as System.Windows.Forms.Label;
string val = EmpId.Text;
But same result, any idea?
please, I hope anyone can help me.
best regards
Try implementing below example, you will get id for selected row
<asp:LinkButton ID="lnkdelete" runat="server" CommandName="Delete" CommandArgument='<%#Eval("ClienteCodigo1")%>'>Delete</asp:LinkButton>
protected void Gridview1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "Delete")
{
int ID = Convert.ToInt32(e.CommandArgument);
//now perform the delete operation using ID value
}
}
Thanks Patrik your solution helped me.

First of all your code and query is not clear.
if i am understanding it right then the problem in your code is that data is not deleting or updating.
as i saw in your code, you are holding data in view state. please recheck your code at the stage of GridView1_RowUpdating() and GridView1_RowCommand() (hoping you are using this for delete) events. after deleting/updating the data you should update the view state also.
I am not able to display the Value in a lable in footer. Below is the code
Aspx
<asp:GridView ID="gvallAccount" runat="server" AutoGenerateColumns="False" Width="589px"

You need to have ShowFooter="True" attribute in the GridView tag.

Hi All,
In above written code only EDIT event is being fired & that is only once after that UPDATE,CANCEL no event is being fired. What am i doing wrong?All I want to do is change the GridRow Color on the basis of the value entered in QTY field.
I figured out the problem. The event was not firing because of the same IDs that i had given to the Label in each row. Hope this helpful to someone.
Not sure about your use of IsPostBackEventControlRegistered - I havent seen it used before but it seems that probably you are wiping out your update event by DataBind() every time in Page_Load().
Page_Load is fired every time the page loads which is then changing what the page is doing by resetting the grid.
Try wrapping the control in:
if(!IsPostBack)
{
// bind
}
so that it only does this on the first page load.
