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...
}
}
I have an usercontrol with fck editor for allowing user to add note in my aspx page, which allows the user all kind of text formatting.My need is that I have to access user control from the code behind and collect the content as the same format some one has entered in the fck editor.How can I do this?
(i) Default.aspx and Default.aspx.cs(ii) MyControl.ascx and yControl.ascx.csTo access MyControl.ascx from Default.aspx, we use following in Default.aspx:
But now I am wishing to access in MyControl.ascx.cs from Default.aspx.cs page. By default, I am totally unable to access any control or function exist in MyControl.ascx.cs file or say codebehind.
How do I access the Control (dropdownlist) in current Page from the UserControl? In the UserControl:
String test = ((DropDownList)this.Parent.FindControl("drpdwnlstMainRegion")).SelectedValue; or String test = ((DropDownList)this.Page.FindControl("drpdwnlstMainRegion")).SelectedValue;
It return null on ((DropDownList)this.Parent.FindControl("drpdwnlstMainRegion")) for some reason? BTW ... I am using ASP.NET C# 3.5.
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.
I've created user control named test.ascs with one textbox. Now I added this user control in my default.aspx page. How can i access that textbox value from my default.aspx page?
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)
i have 2 ascx user controls (both with VB code behind) placed in a contentplaceholder inside an updatepanel within a aspx page based on a masterpage... in the first user control i have a gridview and in the second i want to loop through the rows and get values from the first user control's gridview I would like to know how I can access the gridview of the first usercontrol from the second usercontrol please.
I have a UserControl that is on a masterpage... I have created the following property for the userControl in the codebehind:
[Code]....
Now I need to access this control and change that property from an aspx page that uses the masterpage with the control. I'm stuck I cannot seem to find the controls property. I can find the control and make it visible or not but I cannot find the property to modify control...
I just started learning silverlight by creating a silverlight application in Visual Web Developer 2008. I have a public property defined in the user control. How do I access this property value in the aspx codebehind page?
I have a javascript embedded in my extended gridview control that reference the grid control. Example:
[Code]....
HTML code:
[Code]....
way to determine the gridview object in javascript. I want to make it generic so that if I use this gridview in any other control it should work instead of hardcoding the name.
I have a scenario where I have a tabstrip on the page and each tabstrip has a usercontrol. On page load i want to display the first tab and based on certain properties on that tab i want to enable or disable other tabs. Can somebody guide me on how to do this. I am unable to access the tabstrip control on the parent page from within the usercontrol.
... so that I can access some property of the model inside my Control. Unfortunately this method doesn't work, as I get a message saying "This is not scriptlet. Will be output as plain text".
Is what I'm trying to do even possible? If so, how I can try and do it?
If it's relevant, this is a .Net 4 project, with MVC 2 components.
i have 2 textbox controls inside a usercontrol TextBoxUC.ascx i have a page.aspx that contains the usercontrol. how can i get a reference to each textbox using javascript from page.aspx?
I have a usercontrol on the content page. I'm trying to access this usercontrol's hiddenfield.
I was able to access it before applying the master Page. But once I changed the page to a content page , the value in the hiddenfield is showing empty.
alert(document.getElementById('<%=hidLat.clientID%>').value) is showing the value.
I have a property PickupHidLat defined on the ascx page and I'm using this property to access hidLat value on the content page.
I wanna write a usercontrol to handle different access levels on pages.
Below is the html i wanna achieve.
[Code]....
This is my code at this point:
[ParseChildren(false), PersistChildren(true)] public partial class RequiredUserType : System.Web.UI.UserControl { public string UserTypes { get; set; }
[Code].....
My problem is that the <Content> and <AlternativeContent> doesn't get rendered as Panels and on the Client side its rendered as the initial tags(<Conten>) and not a div or whatever a asp:Panel normally gets converted to.
I have several usercontrols which are loaded based on business logic.However, all of them have webcontrols whose selected/entered value needs to be accessible in parent page on an event.Since there can be any combination of UserControls, I do not want to load all the UserControls in the Parent Page, since they are heavy.
I would like to load only those controls which are supposed to appear on the page, yet access the value from the usercontrol which caused the postback. (I would rather not access using Request.Form) (ViewState is open, but unsuccessful to store value in parent page's viewstate in onClick)Here is a sample scenario
Page: Home
Dynamically Loads: UserControls1
UserControls has TextBox tb and Button btn, causing onClick
When btn is clicked, I want to get value of tb in parent page on PostBack, Page creates UserControl2
I've a ASP.Net page (Default.aspx) which will load UserControl (ucontrol.ascx) dynamically into an UpdatePanel. By using UpdatePanel, we believe we're able to prevent the entire page to be posted-back.
My problem is, within the UserControl, we have some form controls, such as inputs and buttons; after the UserControl is loaded, clicking on any button inside the UserControl will cause the UpdatePanel to be blanked. During the investigation, I found that, breakpoints within the Button1_Click() in the code-behind for the UserControl is never reached. Please reference to the code below, this references to [REFERENCE]1.
