Access One UserControl From Another Using ASP

Oct 7, 2010

I have created a user control UserVote that has property to find total vote on particular question. Now I want to call it from an aspx page.The control code-behind (UserVote.ascx.cs) looks like:

public partial class UserVote : System.Web.UI.UserControl
{
protected void Page_Load(object sender, EventArgs e)
{
DataTable dtVoteInfo = ShowVoteDetail(objectType, objectId);
if (dtVoteInfo != null)
{
if (dtVoteInfo.Rows.Count > 0)
{
int.TryParse(dtVoteInfo.Rows[0]["TOTAL_VOTE"].ToString(), out currentVote);
int.TryParse(dtVoteInfo.Rows[0]["MY_VOTING"].ToString(), out myVoting);
}
}
ltrVotes.Text = currentVote.ToString();
hfCurrentVote.Value = currentVote.ToString();
hfMyVote.Value = myVoting.ToString();
// ...snipped for brevity...
}
}

The control markup (UserVote.ascx) looks like:

<div class="vote-cell" style="width: 46px; height: 92px">
<img src ="~/UserControls/Vote/Images/Arrow Up.png"
id = "voteupoff"
runat = "server" alt ="vote up"
class="voteupImage"
style="height: 45px; width: 45px"/>
<div class="vote" style ="text-align:center; color:#808185;font-weight:bold;">
<asp:Literal ID="ltrVotes" runat="server" ></asp:Literal>
</div>
<img src ="~/UserControls/Vote/Images/arrow_down.png"
id ="votedownoff"
runat = "server" alt = "vote down"
class = "votedownImage"
style="height: 45px; width: 44px; margin-left: 0px;" />
</div>
My page code-behind (viewanswer.aspx.cs) looks like:
UserVote Voteing = (UserVote) **what i write here...**.findcontrol(voting)
Voteing.objectType =300;
Voteing.object id= 2;

My page markup (viewanswer.aspx) looks like:

<klmsuc:Voteing ID="Voteing" runat="server" />

JQuery :: How To Access Span From HTML To Codebehind Without Using Runat = Server Tag

Dec 7, 2010

I have a span control which I am filling using Jquery. At the page load I want this span say id1 to be invisible and depending on some conditions I am making it visible via jquery itself.

When I make id1 runat = server and try to access id1 from codebehing, then I get an error in Jquery.

Hence I need a way to make id1 invisble at the load time itself.

I have already set id1 = invisble in HTML, But still I see this control on the page till the time jquery fills the entire data.

Can't Access Page Viewstate In Usercontrol?

Jun 11, 2010

I stored a object in viewstate on Page. Now when i access the same viewsate object on usercontrol,it shows as null. I even tried creating the same viewstate with same name in usercontrol and page.Both holds different value. I understand that viewstate is a protected property. How does this thing implement in above scenerio or is there any other reason for this behaviour.

Edit:

Usercontrol is there in the page markup. I am not loading it dynamically. I have a page EditFacilityworkType.aspx. On page I have a usercontrol FacilityWorkTypeDetails.aspx(FacilityWorkTypeDetails1). Inside this usercontrol i have a user control Workflow.aspx(Workflow1)

Page_Load() of Page I am retrieving workflowdetails on page_load() of page.

FacilityWorktype facilityWorkType = facilityDetails.GetFacilityWorktypeDetail(SessionHelper.FacilityWorkTypeID);
ViewState["WorkFlow"] = facilityWorkType.FacilityWorkTypeWorkFlow
Inside usercontrol FacilityWorkTypeDetails.aspx. I have a property
public FacilityWorktype FacilityWorkTypeDetails
{
get
{
#region Fill FacilityWorktype
return GetEntityFromControl();
#endregion
}
set
{
PopulateControls(value);
}
}

Now i set this property in page load of page

FacilityWorkTypeDetails1.FacilityWorkTypeDetails = facilityWorkType;
Inside Workflow.aspx, I have a property
/// <summary>
/// Property to fill entity object from controls on this page
/// </summary>
public WorkFlow WorkFlowDetails
{
get
{
return GetEntityFromControls();
}
set
{
BindTranscriptionMethodDDL(ddlTranscMethod);
PopulateControls(value);
}
}
Now PopulateControls() of FacilityWorkTypeDetails1, i am setting property of workflow1
private void PopulateControls(FacilityWorktype value)
{
Workflow1.WorkFlowDetails = value.FacilityWorkTypeWorkFlow;
}

Now when i am retrieving values from

private WorkFlow GetEntityFromControls()
{
WorkFlow workFlow = (ViewState["WorkFlow"] as WorkFlow) ?? new WorkFlow();
//workFlow is null
}

So now inside this function workFlow is null. I want to ask,why is it null when i have set viewstate in page.

Wrap CustomValidator In A UserControl But Allow Access To It?

May 25, 2010

I've got a UserControl that is essentially just a TextBox with optional built-in validators to it. At the moment this is just a RequiredFieldValidator and RegexValidator. It's easy to just expose properties on the UserControl which get passed through to these validators and allow me to set the RegEx for example.

Now I'd like to add a CustomValidator and allow the user to add a server-side validation function... and this is causing me some trouble. What is the proper syntax for this? I tried just adding a ServerValidateEventHandler property, but when I try to use this I get a runtime error:

Cannot create an object of type 'System.Web.UI.WebControls.ServerValidateEventHandler' from its string representation 'valState_ServerValidate' for the 'ServerValidate' property.

Do I need to expose a delegate in some other way? This should be easy... I'm missing one little key. I'm trying to add a CustomValidator to a page which uses the UserControl... I want the user to specify a handler for custom validation on the usercontrol itself. (yes, it's a bit of a Frankencontrol)

While running ItemDetabound upon load of a listivew, I am trying to access the text in a label of the LayoutTemplate of a different Listview. It works fine if I try access the same labels under the same names if they are in the same listview, but not if they are in a different one. It was working for a while, can't figure out what I changed, but now says that object doesn't exist.
