RadGrid allocate checkbox control within detailtable

the master table row must be expanded to open the detailtable before the value of the control can be accessed:

lost designer.aspx in asp.net web application

to fix it, right click on the aspx page in solution explorer and select Convert to Web Application"

RadGrid: rebind detailtable after command execution

e.Item.OwnerTableView.Rebind();

this only rebinds the detailtable, so the current expanding status will remain.

fetch the record primary key from MasterTable while using FormTemplate for insert and update

when you have a FormTemplate for insert and update in RadGrid.MasterTable, there is no commangArgument, therefore the record's primary key can not be passed on using commandargument.


This can be done by

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
{
if (e.CommandName == "Update")
{
int RecordId= Convert.ToInt32(RadGrid1.MasterTableView.DataKeyValues[e.Item.ItemIndex]["RecordId"].ToString());
}
}

RadGrid: rebind detailtable from external event

protected void ReBindExpandedDetailTable()
{
foreach (GridDataItem item in RadGrid1.Items)
{
string aaaValueString= item.GetDataKeyValue("aaa").ToString();

if (aaaValueString== )
{
if (item.Expanded == true)
{
GridTableView nestedView = ((GridDataItem)item).ChildItem.NestedTableViews[0];
nestedView.Rebind();
}
}
}
}

RadGrid: hide add new and refresh buttons from code behind

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
if (e.Item is GridCommandItem)
{
GridCommandItem cmditm = (GridCommandItem)e.Item;
//to hide AddNewRecord button
cmditm.FindControl("InitInsertButton").Visible = false;//hide the text
cmditm.FindControl("AddNewRecordButton").Visible = false;//hide the image

//to hide Refresh button
cmditm.FindControl("RefreshButton").Visible = false;//hide the text
cmditm.FindControl("RebindGridButton").Visible = false;//hide the image


}
}

RadGrid: problem displaying bool value in formtemplate type edit form insert mode

I was able to update any records in the grid. However when I clicked on Add New Record, I received an error "specified cast is not valid" on the boolean field "IsActive".

see code below for my ASPX page content


The solution is:

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
{


if (e.CommandName == RadGrid.InitInsertCommandName)
{
GridEditCommandColumn editColumn = (GridEditCommandColumn)rgQualificationList.MasterTableView.GetColumn("EditCommandColumn");
editColumn.Visible = false;

e.Canceled = true;
//Prepare an IDictionary with the predefined values
System.Collections.Specialized.ListDictionary newValues = new System.Collections.Specialized.ListDictionary();

//set initial checked state for the checkbox on init insert
newValues["IsActive"] = false;

//Insert the item and rebind
e.Item.OwnerTableView.InsertItem(newValues);
}

sorting problem - RadGrid GridTemplateColumn

my code that has problem sorting template columns:



the instruction says "the SortExpression value should match the data field you want to sort on (typically the field a control in the template is bound to)". I made sure this rule is applied but the problem remained. Then I removed the HeaderTemplate components, instead I added value to HeaderText property in the GridTemplateColumn level. This solved the problem, not sure why though.....

Visual Studio 2005 bug in ASP.NET applications

my web.config has multiple connection strings.
when I right click on a table adapter in a dataset in design view, select "configure...", the dataset configuration window pops up. Naturally you'd just make the changes that you want to the query and click on Finish. If this table adapter doesn't use the first connection string listed in the web.config, visual studio will automatically change the connection string to the first one listed in the web.config.

In order to fix the problem when you first open up the configuration window click on Previous to go back to the connection string selection view, RESELECT the connection string. If you happened to encounter this error until this stage right click on the empty area of the dataset design view and select View Code. Then delete the unused connection string.

string.format new line partially works (C#, ASP.NET)

see below my code. every "\n" works fine except the ones after "Event: {0}" and "Start Date: {1:D}", basically the Event, Start Date and End Date are printed on same line. can anyone help please? thanks in advance.

string.Format(



"Schedule Details: \n" +

"Event: {0}\n"+


"Start Date: {1:D} \n" +

"End Date: {2:D} \n" +

"Location: {3} \n"


,schedule.event,
schedule.startDate,
schedule.endDate,
schedule.location);

I tried ""Event: {0}"+ Environment.NewLine" and "Event: {0}\r" and "Event: {0}/r/n" got the same result
==============

Schedule Details:

Event: Basketball Match Start Date: Friday, 1 May 2009 End Date: Tuesday, 30 June 2009

Location: Como
================

Then I tried "Event: {0}\n"+ Environment.NewLine" and "Event: {0}\r"+ Environment.NewLine" and "Event: {0}/n/r" got this result (an additional line)
==============


Schedule Details:

Event: Basketball Match

Start Date: Friday, 1 May 2009 End Date: Tuesday, 30 June 2009

Location: Como
================

It seems that it works either for no newline or 2 new lines, but not for 1 newline. I tried to take out "Event" everything else worked just fine, so the problem must be with "Event"?

The Event has datatype of "string", startDate and endDate are datetime, location is string. A sample of Event value is "Attend Class Certificate III in Basketball".

Eventually the problem is solved, not sure why though.....:

I put single quotes around the Event value, not sure how exactly but it worked.
"Event: '{0}'\n"+

"postback" event not related to REVIOUS and NEXT button on Internet Explorer?

in my case PageA has a buttonA that opens PageB. The code is "response.redirect("PageB.aspx");"

on PageB I have some methodM to call under condition "if (!IsPostBack)"

After I clicked on ButtoA to open PageB, methodM is trigerred.

but when I use the PREVIOUS button on Internet Explore to go back to PageA and click on NEXT button to go back to PageB the methodM didn't fire.

How can I catch the Previous and Next button click event?

the answer is adding the code below into Page_Load in the target page, this line of code will force the target page to load from server instead of cache

Response.Cache.SetCacheability(HttpCacheability.NoCache);

An old joke about project manager

A tourist walked into a pet shop and was looking at the animals on display. While he was there,another customer walked in and said to the shopkeeper, "I'll have a C monkey please." Theshopkeeper nodded, went over to a cage at the side of the shop and took out a monkey. Hefitted a collar and leash, handed it to the customer, saying, "That'll be £5,000."

The customer paid and walked out with his monkey.

Startled, the tourist went over to the shopkeeper and said, "That was a very expensive monkey. Most of them are only a few hundred pounds. Why did it cost so much?" The shopkeeperanswered, "Ah, that monkey can program in C - very fast, tight code, no bugs, well worth themoney."

The tourist looked at a monkey in another cage. "Hey, that one's even more expensive! £10,000! What does it do?"

"Oh, that one's a C++ monkey; it can manage object-oriented programming, Visual C++, even some Java. All the really useful stuff," said the shopkeeper.

The tourist looked around for a little longer and saw a third monkey in a cage of its own. The price tag around its neck read £50,000. The tourist gasped to the shopkeeper, "That one costs more than all the others put together! What on earth does it do?"

The shopkeeper replied, "Well, I haven't actually seen it do anything, but it says it's a project manager".

PL/SQL DBMS_OUTPUT.PUT_LINE formating experience

for the header row, do this:
DBMS_OUTPUT.PUT_LINE(rpad(‘ID’,5) || rpad(‘LAST_NAME’, 15) || rpad(‘FIRST_NAME’,15) || lpad(‘ANNUAL_SALARY’,11) || lpad(‘TAX’,11) || lpad(‘COMMISSION_PCT’, 16));
DBMS_OUTPUT.PUT_LINE(rpad(‘____ ’,5) || rpad(‘_______________’, 15) || rpad(‘_______________’,15) || lpad(‘___________’,11) || lpad(‘___________’,11) || lpad(‘______________’, 16));

then in the loop I did:
DBMS_OUTPUT.PUT_LINE(rpad(r_emp.id,5) || rpad(r_emp.last_name, 15) || rpad(r_emp.first_name,15) || lpad(v_an_sal,11) || lpad(v_tax,11) || lpad(v_com_pct, 16));

not very enjoyable way of formating, but it worked......
