i have added a usercontrol using designer i want to set public properties of this user control but how to access the instance of this user control?
in the designer its showing the usercontrol name as uc3:Pager#Pager1
I have a UserControl that contains a DropDownList and an ObjectDataSource. That control is used in the markup of my MasterPage.
In the Designer of a ContentPage that uses that MasterPage I can see the DropDownList and the ObjectDataSource. See for yourself.
I know that other controls (like ComponentArt:Grid) only show themself as outer container and hide the inner controls.
I guess that is somehow achievable with attributes. Which ones do I have to set?
I have a ajax tabpanel where i add the "tab content" dynamicly with use of iframe. In one of the iframes i have to add a user control (menu bar) to the page, but (ofcource) when i add the usercontrol it end up in the iframe from where it was added.Is there anyway to set the position outside the iframe?. I set the position trough a public property of a hiddenfield. The position is then set with javascript.

Withing Microsoft's Visual Web Developer 2010 Express, I am trying to link an MS Access 2000 database to a web form using the Toolbox tool provided with the program. In the second dialog box where you specify the database to use, it shows that the Data_App folder is empty, yet in the windows explorer window the file is clearly there.
Is this a limitation of the evaluation version, too old of Access database file, or something stupid that I am doing? I gotta admit, I am a newby to .NET and ASP.NET, but I can create other aspx web forms with no problems.
I can connect to the MS Web Server, for instance.
I'd use MySQL, but it doesn't want to work on my computer.
That is the other post I made to Bytes.
maybe it's a dumb question, how can i see the designer generated codebehind files (named .designer.aspx.cs) in VS2010?

I have a FileSystem based asp.net 2.0 app that uses Sql Server 2005 Express database.
I have only one dataset for this app with only 4 tables. After i have completed it to a part, a co-worker have added some Classes to it, which are not in same namespace of myBLL classes.
Then i tried added a new table to the dataset. It like all other tables in that dataset uses SQL Statements to access and manage data.
The problem started after i added that new table. I cannot access it from code. I can access all previous TableAdapters but not this new one.
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" />
I have a grid which uses an objectdatasource. Data is correctly retrieved using the select method. When I add a new record a new row appears in the grid and I can enter my data. I do have access to the row on saving as I can access this new row from the Grid's insert method - using the GridRowEventArg like so (this is using an Obout grid control but the principle can be seen):
protected void WeekTimeListGridView_InsertCommand(object sender, Obout.Grid.GridRecordEventArgs e)
I'm dynamically adding a DropDownList to the GridView in edit mode and I have set the TextBox Visibility to False. In edit mode I can see the DropDownList and I'm able to select an Item from the DropDownList but not able to access the SelectedValue in RowUpdating Event. How to get the selectedvalue of this DropDownList?
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow And (e.Row.RowState And DataControlRowState.Edit) > 0 Then
Dim ddl as DropDownList
FillStateList(ddl)
e.Row.Cells(4).Controls.Add(ddl)
ddl is the DropDownList that is added dynamically. And the default Textbox that is in the Edit mode is set to invisible. So there are actually two controls in the same cell in edit mode(TextBox is invisible).
DirectCast(Gridview1.Rows(e.RowIndex).FindControl("ddl"),DropDownList).SelectedValue
If I use the above statement I'm getting NullException.This is Probably because its a BoundField. Is there a way I can access the DropDownList 'ddl' SelectedValue?

View 5 RepliesHow 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?
View 3 RepliesI'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.
