Gridview Pageindexchanging事件疑问 [英] Gridview Pageindexchanging event doubt
问题描述
场景
- 我有一个下拉
- 选择更改的下拉事件...网格填充。 ...允许分页成为现实
- 当我导航到第二页时我收到错误
Microsoft Jscript运行时错误：
system.webform.pagerequestmanagerservererrorexception：
gridview'GridzeroApprovedKm'触发了未处理的事件PageIndexChanging。
-------------------------------------------- --- aspx页面------------------------------
Scenario
--I have a drop down
--On select changed event of drop down ...grid populates....allow paging is made true
--When i navigate to second page i get error
Microsoft Jscript Runtime error:
system.webform.pagerequestmanagerservererrorexception :
The gridview 'GridzeroApprovedKm' fired event PageIndexChanging which wasnt handled.
-----------------------------------------------aspx page------------------------------
<asp:GridView ID="GridZeroApprovedKm" AllowPaging="true" runat="server" AutoGenerateColumns="false"
DataKeyNames="Address_id" OnRowCancelingEdit="GridZeroApprovedKm_RowCancelingEdit"
OnRowDataBound="GridZeroApprovedKm_RowDataBound" OnRowDeleting="GridZeroApprovedKm_RowDeleting"
OnRowEditing="GridZeroApprovedKm_RowEditing"
OnRowUpdating="GridZeroApprovedKm_RowUpdating"
onpageindexchanging="GridZeroApprovedKm_PageIndexChanging">
-------------------代码背后 - 填充GridView -------------------- ---------
- 网格人物
-------------------Code Behind - Populating the GridView -----------------------------
--here the grid popultes
protected void ddlhub_SelectedIndexChanged(object sender, EventArgs e)
{
TMS.Business.INT_ApprovedKm ApprovedKmObjdis = new TMS.Business.INT_ApprovedKm();
DataSet Approveddata = new DataSet();
Approveddata = ApprovedKmObjdis.GetZeroApprovedKm(ddlhub.SelectedValue);
GridZeroApprovedKm.DataSource = Approveddata;
GridZeroApprovedKm.DataBind();
}
---------- ------------ GridView的PageIndexChange事件处理程序----------------
----------------------PageIndexChange Event Handler of GridView----------------
protected void GridZeroApprovedKm_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridZeroApprovedKm.PageIndex= e.NewPageIndex;
TMS.Business.INT_ApprovedKm ApprovedKmObjdis = new TMS.Business.INT_ApprovedKm();
DataSet Approveddata = new DataSet();
Approveddata = ApprovedKmObjdis.GetZeroApprovedKm(ddlhub.SelectedValue);
GridZeroApprovedKm.DataSource = Approveddata;
GridZeroApprovedKm.DataBind();
}
再次我试图通过写作来填充网格上面的代码。
我在哪里做错了？
---我的理解是<当我导航到下一页时，
。下拉列表中有选择但没有在第一页中选择的值。
- 这可能是它不工作的原因
- 如果这是问题....那么当我导航到下一页....应该选择下拉，因为它在第一页被选中。 .so选择的更改事件将触发并且网格将填充
- 如果我错了，请纠正我
- 也请告诉我如何解决这个问题
- 这是我的页面加载事件
Again I am trying to populate the grid by writing the above code.
Where i am doing wrong ?
---what i understand is
when i navigate to next page. the dropdown is having "select" but not the value that is selected in first page.
--so that may be the reason why its not working
--if this is the problem....then when i navigate to next page....the drop down should be selected as it was selected as in first page...so that the selected change event will fire and the grid will populate
--correct me if i am wrong
--also please tell me how to solve this
--this is my page load event
protected void Page_Load(object sender, EventArgs e)
{
try
{
if (!Page.IsPostBack)
{
ControlBinding.FillCombo(ddlhub, "HUB_MASTER", Session[TMS.Common.CommonConstants.CONST_COMPANY_ID].ToString(), Session[TMS.Common.CommonConstants.CONST_USER_HUB_ID].ToString(), Session[TMS.Common.CommonConstants.CONST_USER_ID].ToString(), "", "", "", false);
}
for (int count = 0; count < ddlhub.Items.Count; count++)
{
ddlhub.Items[count].Attributes.Add("title", ddlhub.Items[count].Text);
}
}
catch (Exception ex)
{
LogError.WriteError(ex);
}
finally
{
}
}

onpageindexchanging=\"GridZeroApprovedKm_PageIndexChanging\"
replace this Code with this
OnPageIndexChanging = \"GridZeroApprovedKm_PageIndexChanging\"
onpageindexchanging="GridZeroApprovedKm_PageIndexChanging"
replace this Code with this
OnPageIndexChanging = "GridZeroApprovedKm_PageIndexChanging"
--Sorry guys
onpageindexchanging=\"GridZeroApprovedKm_PageIndexChanging\"
this is working

But when i clean and build again.....now its working...
