I Have a 2 tables in database w/c are connected
tblPackage
id Name
1 Package A
2 Package B
tblDetails
id PackageID Details
1 1 PackageDetails11
2 1 PackageDetails12
3 1 PackageDetails13
4 1 PackageDetails14
5 2 PackageDetails21
6 2 PackageDetails22
7 2 PackageDetails23
Now i want it to manipulate it on a repeater
HTML
<asp:Repeater ID="rptrPackage" runat="server">
<ItemTemplate>
<asp:Label id="Pack" runat="server" Text='<%# Bind("Pack") %>'></asp:Label>
<asp:BulletedList id="Details" runat="server">
</asp:BulletedList>
</ItemTemplate>
</asp:Repeater>
ASP
private void Populate()
{
DataTable dtPackage = tblPackage();
DataTable dtDetails = tblDetails();
rptrPackage.DataSource = dtPackage;
rptrPackage.DataBind();
}
Try this
aspx
<asp:Repeater ID="rptrPackage" runat="server">
<ItemTemplate>
<asp:Label ID="Pack" runat="server" Text='<%# Bind("Pack") %>'></asp:Label>
<asp:HiddenField ID="hID" Value='<%# Eval("PackageID") %>' runat="server" />
<asp:Repeater runat="server" ID="rptDetails">
<HeaderTemplate>
<ul>
</HeaderTemplate>
<ItemTemplate>
<li>
<%# Eval("Details")%>
</li>
</ItemTemplate>
<FooterTemplate>
</ul>
</FooterTemplate>
</asp:Repeater>
</ItemTemplate>
</asp:Repeater>
code behind
private void Populate()
{
DataTable dtPackage = tblPackage();
DataTable dtDetails = tblDetails();
rptrPackage.DataSource = dtPackage;
rptrPackage.DataBind();
foreach (RepeaterItem item in rptrPackage.Items)
{
Repeater rptDetails = ((Repeater)item.FindControl("rptDetails"));
rptDetails.DataSource = dtDetails.Select("PackageID = " + ((HiddenField)item.FindControl("hID")).Value).CopyToDataTable();
rptDetails.DataBind();
}
}
Using SqlDataSourse inside repeater ,
<asp:Repeater ID="rptrPackage" runat="server" >
<ItemTemplate>
<asp:HiddenField ID="PackID" runat="server" Value='<%# Eval("id") %>'
/>
<asp:Label id="Pack" runat="server" Text='<%# Eval("Name") %>'></asp:Label><br/>
<asp:BulletedList ID="Details" runat="server"
DataSourceID="SqlDataSource1" DataTextField="Details"
DataValueField="id">
</asp:BulletedList>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:YourConnectionString %>"
SelectCommand="SELECT * FROM [tblDetail] WHERE [PackageID] = #PID" >
<SelectParameters>
<asp:ControlParameter Name="PID" Type="Int32" ControlID="PackID" PropertyName="Value" />
</SelectParameters>
</asp:SqlDataSource>
</ItemTemplate>
</asp:Repeater>

I have a parent grid GVInvoiceDet. CRUD operation on this grid is working fine. In each row of the parent, I have child grid GVTaxDetails which opens on click of image ie expand/collapse feature.
I am looking for CRUD within child grid also. But when I click on edit within child, the texbox for editing doesn't appear and the parent grid collapses.
Here is child grid rowediting code
protected void GVTaxDetails_RowEditing(object sender, GridViewEditEventArgs e)
{
GridView gvTemp = (GridView)sender;
gvUniqueID = gvTemp.UniqueID;
//gvEditIndex = e.NewEditIndex;
gvTemp.EditIndex = e.NewEditIndex;
GVInvoiceDet.DataBind();
}
Parent row editing code
protected void GVInvoiceDet_RowEditing(object sender, GridViewEditEventArgs e)
{
GVInvoiceDet.EditIndex = e.NewEditIndex;
GVInvoiceDet.DataBind();
BindItemGrid();
}

I got the work done... Posting the code for others if come across similar situation.
In parent rowdatabound have added code to keep the div open and update the editIndex.
protected void GVInvoiceDet_RowDataBound(object sender, GridViewRowEventArgs e) {
GridViewRow row = e.Row;
if(row.RowType == DataControlRowType.Header)
{
return;
}
else if (row.RowType == DataControlRowType.DataRow )
{
//Find Child GridView control
GridView gvTax = new GridView();
gvTax = (GridView)row.FindControl("GVTaxDetails");
if (gvTax.UniqueID == gvUniqueID)
{
gvTax.EditIndex = gvEditIndex;
//Expand the Child grid
ClientScript.RegisterStartupScript(GetType(), "Expand", "<SCRIPT LANGUAGE='javascript'>expandcollapse('div" + ((DataRowView)e.Row.DataItem)["itemcd"].ToString() + "','one');</script>");
}
}
}
expandcollapse is function on aspx side:
function expandcollapse(obj, row) {
var div = document.getElementById(obj);
var img = document.getElementById('img' + obj);
if (div.style.display == "none") {
div.style.display = "block";
if (row == 'alt') {
img.src = "Images/minus.png";
}
else {
img.src = "Images/minus.png";
}
img.alt = "Close View Taxes";
}
else {
div.style.display = "none";
if (row == 'alt') {
img.src = "Images/plus.png";
}
else {
img.src = "Images/plus.png";
}
img.alt = "Expand View Taxes";
}
}
I need the button inside the datalist to open another page. However the response.redirect does not work !
here is the html
<asp:Content ID="Content3" ContentPlaceHolderID="ContentPlaceHolder2" runat="Server">
<div id="content">
<!-- Review -->
<div class="products">

<h4>Items you have purchased</h4>
<br />
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>"></asp:SqlDataSource>

<asp:Label ID="bookname" runat="server" Text='<%# Eval ("Title") %>'></asp:Label>
<asp:Button ID="review" runat="server" Text="Review" CommandName="review" />
</ItemTemplate>
</asp:DataList>
<br />
</div>
</div>
below is the cs file
public void DataList1_ItemCommand(Object source, DataListCommandEventArgs e)
{
if (e.CommandName == "review")
{
DataList1.SelectedIndex = e.Item.ItemIndex;
Label bookid = (Label)DataList1.SelectedItem.FindControl("Bookid");
Response.Redirect("Review.aspx");
}
}
You still need to attach ItemCommand event to DataList1.
<asp:DataList OnItemCommand="DataList1_ItemCommand" ...>
...
</asp:DataList>
Try Server.Transfer("Review.aspx", true);
Just want to ask how can I find hiddenfield in repeater because my problem I have button and I want to get the associate hiddenfield inside ItemTemplate because I get null value when I try to get hiddenfield value
<asp:Repeater ID="rp_resList" runat="server" OnItemDataBound="rp_resList_ItemDataBound">

protected void imgbtnBookmark_Click(object sender, System.Web.UI.ImageClickEventArgs e)
{
Bookmark bm = new Bookmark();
HiddenField hiddenField = rptGroup.FindControl("hf_resID") as HiddenField;
bm.UserID =
Guid.Parse(Membership.GetUser(HttpContext.Current.User.Identity.Name).ProviderUserKey.ToString());
bm.Resoursce.ResourceID = Convert.ToInt32(hiddenField.Value);
Bookmark.Insert(bm);
}
Try this, change you button tag to pass id as CommandArgument value
<asp:ImageButton ID="imgbtnBookmark" runat="server"
OnClick="imgbtnBookmark_Click"
CommandArgument='<%# Eval("Id") %>'/>
in your button click event you can access id using
bm.Resoursce.ResourceID = Convert.ToInt32(e.CommandArgument.ToString());
Change rptGroup.FindControl("hf_resID") as HiddenField; to
e.Item.FindControl("hf_resID")....
I hope this link will help you .

One thing that I notice, which I suspect is just somehow missing from copy and paste is that the first is missing. I don't think it'd compile so I'm guessing that's not existing in your code. However, it's worth checking.
Your error is probably caused by having the SqlDataSource inside the TemplateField. Move those outside of the DetailsView and give it a whirl.

Alter your SqlDataSource directly for DropDownList5
Your error is now probably caused by the SqlDataSource1 trying to access a Label from inside the DetailsView. This can't really happen, so alter the parameter directly.
Change your parameter type

ConnectionString="<%$ ConnectionStrings:ConnectionStringEvent %>"
ProviderName="<%$ ConnectionStrings:ConnectionStringEvent.ProviderName %>"
SelectCommand="SELECT REASON, LEAVECODE FROM BWLEAVRSN">
<SelectParameters>
<asp:Parameter Name="LEAVECODE" Type="String" />
</SelectParameters>
</asp:SqlDataSource>
Alter the Parameter
protected void DropDownList6_SelectedIndexChanged(object sender, EventArgs e)
{
DropDownList lvtype = (DropDownList)(DetailsView1.FindControl("DropDownList6"));
string selectedValue = lvtype.SelectedValue.ToString().ToUpper();
if (selectedValue == "4 " || selectedValue == "1F")
{
DropDownList lvreason = (DropDownList)(DetailsView1.FindControl("DropDownList5"));
SqlDataSource1.SelectParameters["LEAVECODE"].DefaultValue = selectedValue;
lvreason.Visible = true;

I have a Page which has a 2 level web tab . The Content tabs FIXED and VARIABLE in turn has a web tab. This web tab is loaded with a User control which has a gridview.
My problem is the textboxes in the Gridview are not cleared on going from one sub tab to next sub tab . I tried all possible methods :
1.Bind grid to null ( datasource and DatasoruceId )
2. grid dispose
3. grid columns clear
No luck !!!.. HELP!!!
Note : I am modifying the data in the textboxes from javascript.

The back end code for loading the USer control :
private void LoadInvestmentDetails(int investmentTypeId, WebTab currentWebTab, int tabIndex)
{
Panel panel = GetPanelToBeLoaded(investmentTypeId);
if (currentWebTab.Tabs[tabIndex].Controls.Count == 0)
{
currentWebTab.Tabs[tabIndex].Controls.Add(panel);
budgetDetailsControl.Initialize(investmentTypeId);
budgetDetailsControl.InvestmentDetailsSaved += new ProjectInvestmentDetailsSavedEventHandler(BudgetDetailsControl_BudgetDetailsSaved);
PreviouslyLoadedTab = int.Parse(currentWebTab.Tabs[currentWebTab.SelectedIndex].UserControlUrl);
}
// other code
}
private Panel GetPanelToBeLoaded(int investmentTypeId)
{
System.Web.UI.Control userControl = GetInvestmentDetailsUserControlUrl();
Panel panel = new Panel();
panel.Controls.Add(userControl);
budgetDetailsControl = (IProjectInvestmentDetailsControl)userControl;
budgetDetailsControl.InvestmentTypeID = investmentTypeId;
return panel;
}
private System.Web.UI.Control GetInvestmentDetailsUserControlUrl()
{
return LoadControl(ProjectCommonKeys.URL_PROJECT_BUDGET_DETAILS);
}
The Usercontrol implments the IprojectInvestmentDetails interface and the initalize function of the UC is called first for the binding etc
I figured out the problem. Each user control bound to the sub tab shud be given a unique Id..or else even if we bind new data the data from the earlier instance will persist.
.
private Panel GetPanelToBeLoaded(int investmentTypeId)
{
System.Web.UI.Control userControl = GetInvestmentDetailsUserControlUrl();
**userControl.ID = investmentTypeId.ToString();**
Panel panel = new Panel();
panel.Controls.Add(userControl);
projectInvestmentDetailsControl = (IProjectInvestmentDetailsControl)userControl;
projectInvestmentDetailsControl.InvestmentTypeID = investmentTypeId;
projectInvestmentDetailsControl.UserContext = userContext;
projectInvestmentDetailsControl.PlanningWizardDataManager = PlanningWizardDataManager;
projectInvestmentDetailsControl.PlanningServiceWrapper = PlanningServiceWrapper;
return panel;
}`
Thanks fr the help...
